Semiconductor Test Engineer
Wolfspeed's Global Operations Team is seeking a Test Engineer. This person will be part of a team responsible for all aspects of Power (Schottky diode and MOSFET) and RF device testing on wafer (developing, sustaining, and improving test capabilities). The successful candidate will be a resourceful, hands-on, problem-solver with the capacity to quickly grasp and resolve a wide range of technical challenges with experience in semiconductor test development.
What can you do for Wolfspeed?
- Develop, sustain and improve processes for electrical testing of wafers and devices for Wolfspeed's Power and RF Division
- Generate and maintain complete process documentation, procedures and capacity models for High Voltage (HV) on-wafer Power testing
- Utilize SPC methods to monitor integrity of the HV on-wafer test systems
- Ensure the accuracy and completeness of data that is uploaded to the master data base for archival and data mining
- Maintain calibrated test stations and probe cards (including backups) to minimize tool down time
- Diagnosis problems and implement corrective actions on HV on-wafer test systems
- Oversee training and certification of production personnel on HV on-wafer test systems
- Design and execute electrical/mechanical experiments to improve measurement and process yields
- Develop SW to maximize testing throughput while maintaining product integrity to specifications
- Apply knowledge of object oriented design and good coding practices to develop and validate robust production test software
- Collaborate with other SW engineers to develop and maintain a robust process for SW verification and control
- Generate equipment requirements for capital purchase in line with the new product roadmap and bring those tools on-line within the project schedule
- Work with product development on test strategies that minimize wafer probe requirements while maintaining product integrity to specifications
What you need for success:
- BS in Electrical Engineering, Computer Engineering or an equivalent discipline
- 4+ years of experience in electrical testing, Power Electronics preferred
- High proficiency with VB, .NET, C#, or equivalent language
- Hands-on experience with operation and/or programming of on-wafer test equipment (such as Semiconductor Analyzers, Signal Generators, Power Supplies, DMMs, Oscilloscopes and Curve Tracers)
- Ability to read and understand circuit schematics
- Proficient with data analysis software such as JMP or SAS
- Basic Knowledge of SPC and experimental Design
- High energy, self-motivated attitude with strong communication skills and an ability to interface effectively with different backgrounds, at every level of the organization
- Strong attention to detail while effectively managing time
Highly preferred skills and certifications:
- Experience in power electronics testing
- Experience with modular testing equipment
- Experience with high power, high precision, and high frequency testing equipment
- Experience with SQL Queries
- Extensive data analysis and programming skills (.Net, VB, or C#)
- Extensive experience with SPC and experimental design
- 3+ years of experience in semiconductor wafer level test and manufacturing
- Experience with compound semiconductor FET technologies
- In-depth technical knowledge of semiconductor wafer probing equipment
- Extensive MOSFET and/or diode device level testing experience
