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.
Develop, sustain and improve processes for electrical testing of wafers and devices for Wolfspeeds 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
