Aehr Test Systems announced it has received an initial customer order for a FOX-NP™ wafer level test and burn-in system, multiple WaferPak™ Contactors, and a FOX WaferPak Aligner to be used for engineering, qualification, and small lot production wafer level test and burn-in of their silicon carbide devices. The customer is a US-based multibillion-dollar semiconductor supplier serving several markets including automotive, computing, consumer, energy, industrial, and medical. The FOX-NP system, including the FOX WaferPak Aligner and initial WaferPaks are scheduled per the customer’s requested accelerated schedule to ship by the end of the calendar year 2023.
The FOX-NP system is configured with the new Bipolar Voltage Channel Module (BVCM) and Very High Voltage Channel Module (VHVCM) options that enable new advanced test and burn-in capabilities for silicon carbide power semiconductors using Aehr’s proprietary WaferPak full wafer Contactors. This new order highlights Aehr’s continued progression within the growing silicon carbide global power market.
Gayn Erickson, President and CEO of Aehr Test Systems, commented, “We are very excited that after conducting a detailed financial evaluation and multiple onsite visits to Aehr’s application lab, this new customer selected our FOX-P solution for engineering, qualification, and production of their silicon carbide power devices.
This evaluation included cost of ownership and system throughput, as well as device test, burn-in, and stabilization coverage. As their production capacity increases, they told us that they will quickly move to our FOX-XP multi-wafer test and burn-in systems for high-volume production. In addition to the automotive electric vehicle device opportunity, this customer in particular sees the enormous opportunity for silicon carbide power devices in industrial, solar, and other power applications.
“William Blair forecasts that in addition to the 4.5 million six-inch equivalent wafers that will be needed to meet the demand for electric vehicle related silicon carbide devices in 2030, another 2.8 million wafers are needed to address industrial, solar, electric trains, energy conversion and other applications in 2030. The interesting part of this is that most of these applications will be served with discrete MOSFETS in single die packages.
The cost of ownership of our solution proved to be more cost-effective and efficient for these devices than package part burn-in after the die are packaged in packages such as TO-247 or other discrete packages. This is a strong testimony of the advantage of wafer level burn-in as a better alternative to package part burn-in. This expands our silicon carbide test and burn-in market even more and this new customer helps expand Aehr’s presence in this market as our total addressable market (TAM) continues to grow.
“Aehr’s FOX-P systems and proprietary WaferPak full wafer Contactors enable our customers to do economical production volume test and reliability burn-in with processes such as High Temperature Gate Bias (HTGB) and High Temperature Reverse Bias (HTRB) very cost-effectively and ensure extremely high device quality. Our systems are typically used for long burn-in times lasting up to 24 hours or more.
We can do this for under $5.00 per hour per wafer capital depreciation cost while testing and burning-in up to several thousand devices at a time per wafer. This is also in a test system footprint that is up to 94% less than a typical test system on a standard semiconductor wafer prober, which in a precious clean room wafer facility is extremely important and saves a great deal of cost.
“The FOX family of compatible systems including the FOX-NP and FOX-XP multi-wafer test and burn-in systems and Aehr’s proprietary WaferPak full wafer contactors provide a uniquely cost-effective solution for burning in multiple wafers of devices at a single time to remove early life failures of silicon carbide devices, which is critical to meeting the initial quality and long-term reliability of the automotive, industrial, and electrification infrastructure industry needs.”
The FOX-XP and FOX-NP systems, available with multiple WaferPak Contactors (full wafer test) or multiple DiePakTM Carriers (singulated die/module test) configurations, are capable of functional test and burn-in/cycling of devices such as silicon carbide and gallium nitride power semiconductors, silicon photonics as well as other optical devices, 2D and 3D sensors, flash memories, magnetic sensors, microcontrollers, and other leading-edge ICs in either wafer form factor, before they are assembled into single or multi-die stacked packages, or in singulated die or module form factor.

Korea Electrotechnology Research Institute (KERI) succeeded in transferring the ‘Ion Implantation and its Evaluation Technology for the SiC (silicon carbide) Power Semiconductor’ to a Hungarian company.
Power semiconductors are key components in electricity and electronics, acting as the muscles of the human body by regulating the direction of current and controlling power conversion. There are many different materials for power semiconductors. Among them, SiC is receiving the most attention due to its excellent material properties, including high durability and excellent power efficiency. When SiC power semiconductors are incorporated into electric vehicles, they cut down the power consumption of the battery and reduce the body weight and volume of the vehicle, resulting in energy efficiency improvements of up to 10%
While SiC power semiconductors have many advantages, the manufacturing process is also very challenging. Previously, a method was applied to create a device by forming an epi layer (single-crystal semiconductor thin-film) on a highly conductive wafer and flowing current through that area. However, during this process, the surface of the epi layer becomes rough and the speed of electron transfer decreases. The price of the epi wafer itself is also high, which is a major obstacle to mass production.
To solve this problem, KERI used a method of implanting ions into a semi-insulated SiC wafer without an epi layer. Ion implantation, which makes a wafer conductive, is the work that breathes life into a semiconductor.
SiC materials are hard and require very high energy ion implantation followed by high temperature heat treatment to activate the ions, making it a difficult technology to implement. However, KERI has succeeded in securing the relevant technologies based on its 10 years of experience in operating ion implantation equipment dedicated to SiC.
“Ion implantation technology can significantly reduce process costs by increasing current flow in semiconductor devices and replacing expensive epi wafers,” said Dr. Kim, Hyoung Woo, Director, Advanced Semiconductor Research Center, KERI. He continued, “This is a technology that increases the price competitiveness of high-performance SiC power semiconductors and contributes greatly to mass production.”
This technology was recently transferred to ‘SEMILAB ZRT (CEO: Tibor Pavelka)’, a semiconductor metrology equipment company located in Budapest, Hungary. With a 30-year history, SEMILAB has manufacturing plants in Hungary and the United States. SEMILAB owns patents for medium-sized precision measurement equipment and material characterization equipment, and has the world’s leading technology in semiconductor electrical parameter evaluation system.
They predict that through this technology transfer, they will be able to standardize high-quality SiC. SEMILAB plans to use KERI technology to develop specialized equipment to evaluate the ion implantation process of SiC power semiconductor.
Park Su-yong, the president of SEMILAB Korea, said, “Through the development of specialized equipment, we will be able to progress in-line monitoring of implant processes on SiC wafers for immediate, accurate, and low-cost production control of implant systems and in-line monitoring for pre-anneal implant.” He added, “This will be a great foundation for stably securing a high-quality ion implantation mass production process with excellent uniformity and reproducibility.”
KERI is a government-funded research institute under the NST (National Research Council of Science & Technology) of the Ministry of Science and ICT. It has a total of more than 120 intellectual property rights in the field of power semiconductor research. As of the last 10 years, power semiconductor division of KERI has achieved more than KRW 3 billion in technology transfers, the highest level in South Korea.

Shin-Etsu Chemical Co., Ltd. has determined that QST® (Qromis Substrate Technology) substrate is an essential material for the social implementation of high-performance, energy-efficient GaN (gallium nitride) power devices, and the company will promote the development and launching on the market of these products.
Since QST® substrate is designed to have the same coefficient of thermal expansion (CTE) as GaN, it enables suppression of warpage and cracking of the GaN epitaxial layer and resultant large-diameter, high-quality thick GaN epitaxial growth. Taking advantage of these characteristics, it is expected to be applied to power devices and RF devices (5G and beyond 5G), which have been rapidly growing in recent years, as well as in such areas as MicroLED growth for MicroLED displays.
In addition to sales of QST® substrates, Shin-Etsu Chemical will also sell GaN grown QST® substrates upon customer request. We currently have a line-up of 6″ and 8″ diameter substrates, and we are working on 12″ diameter substrates. Since 2021, for each respective application for power devices, RF devices and LEDs, sample evaluation and device development are continuing with numerous customers in Japan and globally. Especially for power devices, continuous evaluation is underway for devices in the wide range of 650V to 1800V.
So far, Shin-Etsu Chemical has repeatedly made many improvements with regard to its QST® substrates. One example is the significant improvement in lowering defects originating from the bonding process, which has enabled the supply of high-quality QST® substrates. In addition, for the thicker GaN films that many of our customers have requested, we have promoted the provision of template substrates with optimized buffer layers, which enables our customers to realize stable epitaxial growth of more than 10 μm thickness. Furthermore, various successful results have been produced and reported on, including the achievement of thick-film GaN growth exceeding 20 μm using QST® substrates and the achievement of 1800V breakdown voltage in power devices.
Moreover, Shin-Etsu Chemical and Oki Electric Industry Co., Ltd. have jointly succeeded in developing a technology to exfoliate GaN from QST® substrates and bond it to substrates made of different materials using Crystal Film Bonding (CFB) technology. Until now, most GaN power devices have been lateral devices, but CFB technology takes advantage of the characteristics of QST® substrates to realize vertical power devices that can control large currents by exfoliating a thick layer of high-quality GaN from an insulating QST® substrate (see figure below).
To customers who manufacture GaN devices, Shin-Etsu Chemical will provide QST® substrates or GaN grown QST® substrates and Oki Electric Industry will provide its CFB technology through partnering or licensing. In this way, the two companies hope to contribute to the advancement of vertical power devices.
Based on these development results and also based on business situation inquiries from customers, Shin-Etsu Chemical will continue to increase production to meet customer demand.
Shin-Etsu Chemical will contribute to the realization of a sustainable society that can use energy efficiently by further promoting the social implementation of GaN devices that have characteristics that are absolutely essential for the future society.
