Job Description

The Defect Engineer position requires thoroughness while looking for ways to promote quality and improve yield. Responsible for sustaining all released semiconductor-related processing. Major areas of responsibilities include monitoring in-line defectivity levels, resolving in-line yield issues, creating inspection recipes on defect-inspection tools and provide feedback to other Process engineers and management to improve the manufacturing process. Partner with Integration, Process, Equipment and R&D to meet performance, quality and cycle-time requirements. Work with our global team to trouble-shoot, benchmark and improve our processes.

This Job Is For You If

• You have strong technical background to develop and sustain 0.35 to 0.13um RFCMOS/SiGe BiCMOS processes in Defectivity Monitoring, and one or more of Photolithography, Etch, Diffusion, Thin-films, CMP/HVAC, Copper Damascene and Wet-cleans - Experience in Copper CMP is a plus.
• You have experience in sustaining in-line defectivity monitoring tools such as KLA/AMAT defectivity monitoring tools and optical/SEM microscopes.
• You are an expert in investigating, identifying, verifying, and containing sources of particulate contamination in semiconductor manufacturing.
• You have experience in analyzing defect-trend data, dispositioning problem wafers/lots, correlating defectivity type/level to product yield, using statistical process control techniques to improve yields, and providing corrective action recommendations to solve defectivity issues.
• You have the ability to work, and interface with Process Technicians to verify response to daily issues and assist with priority and held lots.
• You have led major and minor projects involving particulate contamination and fab yield issues by working closely with device, integration, process, and other yield engineers.
• You have designed and overseen experiments to enhance functional and fab yield thru defect reduction.
• You have experience in performing analysis of in-line defectivity, E-Test, and Probe data to analyze data from experiments or in-line data to identify and resolve problems.
• You have strong understanding and experience in direct application of statistical process control
• You have experience in utilizing advanced analytical tools/software and techniques to solve wafer fabrication problems.
• Your primary responsibility will be investigating root cause for out-of-control production material, new defect types, and abnormal spatial signatures
• You must react to baseline shifts and defect excursions with a sense of urgency and partner with Fab Engineering to contain, understand, and resolve any problem that may arise while on-shift
• There will be opportunities to lead, influence, and support teams associated with defect-density reduction, defect excursions, and high-impact quality events
• You are required to spend time in the Fab on a daily basis working closely with the on-shift Technicians to resolve inline defect issues and communicate findings to the engineering community through daily interaction with Equipment, Process, and Product engineering counterparts
• You must identify high-impact defect issues and partner with Fab Engineering to implement corrective actions
• Presenting inspection data with clear conclusions to upper management is essential
• You will need to create or update documentation (defect classification guide, disposition specs, etc.) on a regular basis
• You have experience in researching, analyzing and recommending capital equipment requirements for analytical tool purchases.
• You are able to work with other teams and QA to deliver results to customer’s requirements.

Job Requirements

• Minimum requirement is a Bachelor’s degree in Materials Science, Chemistry, Electrical Engineering, Microelectronic Engineering, or Solid-State Physics - Master degree is preferred, New Grads with BSEE encouraged to apply.
• Minimum 3-5 years yield/process engineering experience.
• Demonstrated knowledge of principles, theories, concepts, and techniques of process engineering
• Ability to execute definable portions of a project or lead own small projects
• Ability to use knowledge to provide solutions to a variety of difficult problems.
• Strong organizational Skills; demonstrated ability to manage multiple tasks simultaneously and able to react to shifting priorities to meet business needs
• Demonstrated ability to work well within a global team or environment
• Six-Sigma certification is preferred
• Strong knowledge in using Yield Analysis software
• Strong knowledge in in-line automatic defect inspection tool (application, recipe setup, troubling shooting skill)
• Sustained ownership of day-to-day operations and mentoring technicians
