September 26, 2024
2 Min ReadAxus Technology, a leading global provider of chemical mechanical planarization (CMP) equipment, critical for semiconductor and compound semiconductor fabrication, announced its flagship CapstoneÆ CS200 platform tools offer the industry’s lowest cost of ownership (CoO) for CMP processes on 200mm silicon carbide (SiC) wafers. Compared to its closest competitor, Axus’s small-footprint Capstone delivers twice the throughput at less than half the total cost per wafer.
Yole Group forecasts the overall SiC manufacturing tool market to top US$4.4 billion by 2029. “The unique properties of SiC require specialized manufacturing tools and lines for processing power SiC devices,” the market analyst firm noted earlier this year. Axus anticipated this need, designing the state-of-the-art Capstone from the ground up to deliver advanced processing capabilities for SiC in power electronics and other applications.
“Many 200mm fabs are looking to upgrade their installed base of CMP tools to products with leading-edge capability and functionality. Our ability to deliver industry-low CoO further underscores our strong market position and capacity to support this shift,” said Axus Technology CEO Dan Trojan. “Capstone features a streamlined workflow and integrated cleaning capability, so it requires half the process steps of older CMP tools. This allows customers to greatly lower their capex investment.”
Key Capstone CoO advantages vs. competitor
- Throughput: 2.5x wafers per hour
- Power consumption: 60% lower
- DI water consumption: 80% lower
- Footprint: 45% smaller
- Capex cost per wafer: 65% lower
- Total cost per wafer: 50% lower
Another factor contributing to Capstone’s lower CoO is its built-in Process Temperature Control (PTC) technology, which enables processing at higher pressures and speeds without exceeding temperature limits of polishing pads and other sensitive components. This feature is vital for SiC and other materials with high hardness and planarization challenges that necessitate more aggressive process conditions.
Axus built its proprietary CoO model using its own system specifications, publicly available specs for competitive tools, actual consumables costs, and real-world performance data supplied by customers. The comprehensive model factors in all CoO contributors: process variables (polish time and removal rates), polishing and cleaning consumables, power and deionized (DI) water usage, system footprint, and equipment capex including cost, utilization and wafer capacity.

Toshiba Electronics Europe GmbH enhances its silicon carbide (SiC) diode portfolio with ten new 1200V Schottky barrier diodes (SBDs). The TRSxxx120Hx series, comprising five products housed in TO-247-2L packages and five in TO-247 packages, helps designers improve the efficiency of industrial equipment, including photovoltaic (PV) inverters, electric vehicle (EV) charging stations, and switching power supplies.
By implementing an enhanced junction barrier Schottky (JBS) structure, the TRSxxx120Hx series allows a very low forward voltage (VF) of just 1.27V (typ.). The merged PiN-Schottky incorporated into a JBS structure reduces diode losses under high current conditions. The TRS40N120H of the new series accepts a forward DC current (IF(DC)) of 40A (max) and a non-repetitive peak forward surge current (IFSM) of 270A (max), with the maximum case temperature (TC) of all devices being +175°C.
Combined with the lower capacitive charge and leakage current, the products help improve system efficiency and simplify thermal design. For instance, at a reverse voltage (VR) of 1200V, the TRS20H120H diode housed in the TO-247-2L package provides a total capacitive charge (QC) of 109nC and reverse current (IR) of 2µA.

Canon Inc. announced the release of the FPA-3030i6 i-line stepper, a new semiconductor lithography system for processing wafers with a diameter of 8 inches (200 mm) or smaller.
The FPA-3030i6 employs a newly developed projection lens that boasts high transmittance and high-durability. The system reduces lens aberration for high exposure dose processes and improves productivity by shortening exposure time.
The lens is made of high-transmittance glass material that reduces lens aberrations occurring during exposure by more than 50% when compared to previous stepper models. Higher transmittance also helps reduce exposure time while maintaining pattern fidelity, even under high exposure dose conditions.
Improving lens transmittance will also increase exposure intensity and shorten the exposure time required for each process. The FPA-3030i6 standard productivity for 8 inch (200 mm) wafers has increased to 130 wafers per hour from 123 for the previous stepper models.
Additionally, since the lens is highly durable, lens transmittance decrease over time is reduced and productivity can be maintained over the life of the system.
The NA (numerical aperture) range has also been expanded from 0.45~0.63 in the previous model to 0.30~0.63. Allowing for a smaller NA enables customers to select the optimum NA for each device layer.
Optional products including a wafer handling system for special substrates are available for order to meet users’ manufacturing needs for various emerging semiconductor devices including high-power and high-efficiency green devices.
The FPA-3030i6 is designed to support a wider range of device fabrication thanks to a variety of available process options for silicon (Si) as well as sapphire and compound semiconductor materials such as silicon carbide (SiC), gallium nitride (GaN) and gallium arsenide (GaAs) substrates.
Canon will offer wafer feeding options enabling handling of substrates from 2 inches (50 mm) to 8 inches (200 mm) in diameter, as well as thick, thin and warped substrate handling.
