Quick Summary

We are seeking a Staff Modeling and Characterziation Engineer to characterize and model FETs, and also model cutting edge switching power MOSFETs for 6.75V to 12V VIN applications.

Job Description

【Background】

This team supports SPS FET design for PCP. We currently have limited characterization abilty and no modeling. The SPS FETs are critical for PCP and we are entering a period of incredible growth for SPS FETs where we are looking at volume sales increasing by 3x in the next 2 years.

【Job Description】

We are seeking a Staff Modeling and Characterziation Engineer to characterize and model FETs, and also model cutting edge switching power MOSFETs for 6.75V to 12V VIN applications. You will participate in the full product cycle from conception of architecture through final product characterization. This will involve modeling the FETs for specific application performance, and developing test and characterization methods to demonstrate FET capability and limits. You will support development of test patterns to help charcterize the FETs, and also provide support in developing spice models. You will work in a team of highly experienced device and process integration engineers to develop cost-effective, manufacturable devices for some of the most demanding of power applications. This is a high visibility position with potential to make significant business and technological impacts.

• Providing modeling support to develop novel, high-performance, high-reliability power switching device technology for one of our fast-growing business units
• Work closely with device engineers toward optomizing the FETs for switching applications
• Identify critical design parameters that are key to optimal application performance
• Collaborate with internal CAD and layout teams to develop test mask layouts and parameterized cells (P-Cells)
• Work closely with applications and test engineers to gather characterization data to ensure optimal FET performance in application
• Help identify testing requirements for new technologies based on specific device architectures and application stresses
• Analyze measured device and test structure data to solve problems and optimize device design in the application

*The full details regarding your position scope as well as any future potential changes in work location and job scope will be provided during the interview process.

【MUST】

• Demonstrated track record of application and spice modeling for FETs
• Semiconductor Device Physics / Solid State Physics
• Product and test mask layout (preferably Cadence Virtuoso)
• Experience with application modeling in SIMetrix/Simplis or spice-based simulators
• Working familiarity with power device test and characterization equipment and methodologies
• Understanding of switched-mode power applications 
• Conversational proficiency in English
• Business-level proficiency in Japanese

【WANT】

• TCAD device simulation
• High Voltage VDMOS device engineering
