DISCO Corporation has developed a new ABC (Auto Blade Changer) that can automatically replace hubless blades as an optional function, and it is currently available for purchase. This function is planned to be exhibited at SEMICON Japan 2023 (December 13 – 15, Tokyo Big Sight).
Developmental Background
Dicing saws were originally developed to singulate fully-manufactured semiconductor wafers, but in recent years, dicing saws are also being used in applications such as package dicing following resin molding (QFN packages, etc.), passive component dicing such as condensers and inductors, and dicing optical parts that use glass.
When dicing silicon wafers, the blade used is called a hub blade, and it is attached to an aluminum hub. The Auto Blade Changer (ABC), an automatic replacement function for these hub blades, was developed and has been sold by DISCO since 2005, and has contributed to the improved productivity of the dicing process and the reduction of human errors.
However, manual replacement by an operator was necessary to replace hubless blades that are widely used in applications such as package dicing as mentioned above. This newly developed ABC supports both hubless and hub blades, enabling automatic replacement regardless of the blade type.Features
The new ABC supports blade replacement of both hubless and hub blades.
- Improves operation rates
- Reduces downtime caused by waiting for the operator
- Prevents human error
- Reads the blade ID using a QR code, and automatically fills in values such as the blade exposure
- Contributes to traceability
- Records the blade lot ID used
Supported models
The new ABC can currently be installed in the following three equipment models.
DFD6342：A facing dual spindle dicing saw that supports Φ200 mm wafers
DFD6561：A facing dual spindle dicing saw that supports Φ300 mm wafers

In the world of electric vehicles (EVs), performance and efficiency are paramount. As the EV industry grows, power designers constantly strive to provide more power, reduce losses, minimize heat, and shrink system sizes. These requirements stem from the ongoing pursuit of lighter vehicles with extended ranges, reduced battery size, and lower overall system costs.
The continuous drive for improvement has led to accelerated adoption of a pivotal technology transforming the landscape of EV traction design: Gallium Nitride (GaN). Particularly noteworthy are the benefits of GaN in 400V and 800V battery traction inverter designs. The growing recognition of GaN’s exceptional performance, compared to conventional silicon and SiC alternatives, underscores its critical role in the future of the EV industry.
GaN-Powered 400V Battery Traction Inverters
GaN stands out as a transformative force for 400V battery-based traction inverters—delivering the benefits that designers expect. With GaN, efficiency increases, resulting in nearly 40% reduction in power loss. Additionally, GaN power semiconductors enable a 33% increase in power density, reducing the overall size and weight of the traction inverter. Altogether, the reduced losses and smaller size result in EVs with lower costs and longer driving range, meeting critical consumer requirements.
GaN’s Emergence in 800V Battery Traction Inverters
In 800V battery-based traction inverters, the adoption of GaN-based three-level topology (3LT) is a growing trend. The demonstrated benefits are numerous.
- Higher Overall Efficiency: In addition to minimizing switching losses and increasing efficiency in the inverter, the GaN 3LT solution also reduces high-frequency copper and iron losses in the filters and motor. The inverter plus motor combined efficiency gains translates to incrementally higher efficiency compared to two-level solutions.
- Lower Noise, Harshness, and EMI Interference: The GaN 3LT generates an output voltage with a sinusoidal-like shape, resulting in reduced dV/dt and lower harmonics. The 3LT output reduces filtering requirements and minimizes high-frequency losses in filters and motors, resulting in lower noise, vibration, and harshness (NVH) characteristics. It also operates with a low common voltage, reducing insulation stress and electromagnetic interference (EMI).
- Increased Durability and Reliability: Operating at a lower common voltage also means the peak common mode voltage is suppressed, which reduces the potential for common mode voltage spikes, ensuring a smoother and more stable circuit operation. Furthermore, the 3LT decreases the strain on electric motor bearings. These operating characteristics contribute to a prolonged lifespan with increased durability and reliability.
The EV Market
EVs are at their tipping point, with more than 10 million electric cars sold worldwide in 2022, and sales are expected to grow by 35% this year to reach 14 million cars. Meeting consumer, regulatory, and OEM expectations means peak performance is critical, and this requires a holistic approach that factors in both the inverter and motor considerations. Multi-level GaN is emerging as the lynchpin, offering a range of advantages. Notably, GaN fosters high efficiency at the system level while bolstering overall system reliability.
For example, consider the all-GaN vehicle developed in collaboration with Toyota and Nagoya University teams. The All GaN Vehicle features multiple power applications of GaN in the car: in the traction inverter, the On-Board Charger (OBC), and the DC-DC converter. GaN increased power density and improved efficiency by 20% over silicon, extending the car’s driving range.
Meanwhile, Ricardo, a highly regarded global engineering firm, designed and compared a GaN inverter to a SIC-based inverter. Their test results of the 30kW inverter application demonstrated a 25% reduction in power loss and a 33% increase in power density with GaN compared to SiC. Several Tier1 and OEM automotive companies have realized similar results with traction designs up to 250kW.
In an era of EV innovation, GaN is a driving force accelerating performance and efficiency in both 400V and 800V traction inverters. With the EV industry advancing towards worldwide mass acceptance, the time for GaN adoption is now. The compelling results from rigorous testing and real-world applications point to GaN as the technology well-positioned to reshape the electric mobility landscape.
