Job Description:

Semiconductor wafer fab device engineer with product and technology yield responsibility.  Determines cause of low yields at parametric and wafer sort test, introduces new products into production, supports product and process transfers, and continuously improves product yields and reliability.

Shift: 1st

Responsibilities

• Works closely with wafer fab process engineering, product engineering, design engineering, and test engineering to understand issues/opportunities and drive yield improvement activities.
• Analyzes production and engineering data to identify and resolve product yield issues.
• Designs, coordinates, and analyzes IC manufacturing process experiments to improve product yields and performance.
• Evaluates the parametric and product impact of process experiments.
• Uses evaluation equipment such as manual probe stations, parametric evaluation equipment, bit mappers, and microscopes to collect engineering data, perform failure analysis, and detect circuit and/or fabrication problems causing failures.
• Dispositions maverick material at parametric test and wafer sort.
• Owns responsibility for product/technology including maintenance of yield limits, process change control, new product introduction and yield improvements.
• Supports the introduction of new products and process flows into the fab and parametric test area through the creation, review, and implementation of necessary supporting specifications and process routes and flows.  This may involve supporting transfers from other facilities.
• Plans and completes various technical projects.
