Additional Information
JOB SUMMARY:
Contribute to the development/transfer, optimization, and documentation of the overall process flow and macro modules required to fabricate reliable, manufacturable devices on GaN on Silicon (HEMT), which meet parametric and performance goals.
Characterize, evaluate, and document semiconductor devices to ensure reliability and performance to quality standards.
Evaluate new opportunities for development and/or transfer of new semiconductor technology and processes.
DUTIES AND RESPONSIBILITIES:
Set up and perform process and device simulations to determine initial process parameters, capabilities, and direction for optimization of new process flows.
Design and perform experiments and analyze the results to determine the process sequences and parameters which will yield the target device parameters, by using the results of the process simulations or initial test lots as a starting point.
Analyze data (electrical, in-process measurement or visual inspection) from the fabrication of test lots to determine which parameters require additional optimization.
Work with Process Engineering to develop, characterize, and optimize process modules.
Support the processing of the initial test chip and transfer lots fabricated with the new process to identify and correct any problem areas and work to achieve first-pass success.
Provide inputs to and work with Device Engineers to develop layout rules for the process being developed, using equipment specifications and experimental data.
Recommend test structures for and contribute to the layout of test chip mask sets to aid in developing the new process and evaluating specific process-dependencies of device parameters.
Provide weekly, monthly, quarterly development updates to upper management and external customers.
Support company initiatives, such as; quality, safety and environmental management, CQI, 5S, yield management, and cost containment
Perform other duties as required.
