• Develop novel, high-performance, high-reliability power switching device technology for one of our fast-growing business units
• Work closely with process engineers toward development of new process flows and design rules
• Design and execute TCAD simulation experiments to center critical process and design parameters
• Identify critical design parameters and process sensitivities which affect yield to pre-defined specifications
• Collaborate with internal CAD and layout teams to develop test mask and product mask layouts and parameterized cells (P-Cells)
• Design and analyze process and design of split experiments
• Work closely with applications and test engineers to gather characterization data and ensure robust test methodologies
• 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 and process
• Provide engineering support for existing power semiconductor products What We're Looking For
• Semiconductor Device Physics / Solid State Physics
• Semiconductor Device Process Integration
• TCAD process and device simulation (preferably Sentaurus)
• Conversational proficiency in English
• Business-level proficiency in Japanese Nice to Have
• Product and test mask layout (preferably Cadence Virtuoso)
• Design of Experiments methodology
