1.2 KV SiC MOSFETs fabricated in 150mm CMOS Fab

The agenda of the presentation is as follows:

• Motivation for SiC devices
• SiC MOSFET - market status
• High volume 150mm process
• Performance/ruggedmess validation

- Static characteristics

- Switching characteristics

- Destructive testing

• Application support

The Littelfuse presentation explores the benefits of rugged 1.2KV SiC MOSFETs.

• Reality: ideal switch is not enough
• Long-term reliability: voltage, temperature, moisture, mechanical
• Performance: breakdown voltage, on-resistance, switching loss
• Ruggedness: short-circuit, Avalanche, Surge, ESD
• Cost
• Manufacturability: yield, process, margin

Design specifications

The rugged 1.2KV SiC MOSFETs are designed for manufacturability and ruggedness.

• Epitaxial layer: epi doping variation
• Termination design: dose variation, high field in molding compound
• JFET design: high oxide field
• Channel design: on-resistance vs. device ruggedness
• Source/contact design: design rule

Monolith evaluation kit development
The Littelfuse presentation also delves into the benfits of the monolith evaluation kit development

• The goal is to provide customers with all the tools needed to fully evaluate device performance and reliability
• In addition to evaluation kits there are also extensive app notes and consulting services
