Job Description
Job Summary
The Test Engineer (Semiconductor) is responsible for developing, validating, and supporting test solutions for semiconductor devices across wafer-level and package-level manufacturing. This role works closely with design, process, product, and quality teams to ensure robust test coverage, high yield, and cost-effective test solutions from early silicon bring-up through high-volume production.
Key Responsibilities
- Develop, implement, and maintain wafer sort and final test programs using ATE platforms such as Teradyne, Advantest, Verigy, or equivalent.
- Execute parametric, functional, reliability, and system-level testing of semiconductor devices.
- Debug test failures, analyze yield data, and perform root cause analysis related to design, process, test programs, or hardware.
- Collaborate with design and process teams on DFT, scan, BIST, and test coverage optimization.
- Support silicon bring-up, first silicon debug, and failure analysis activities.
- Optimize test time, throughput, and cost while maintaining test coverage and quality.
- Monitor production yield, binning trends, and test escapes using SPC and data analysis tools.
- Support New Product Introduction (NPI) and transfer of test programs from engineering to manufacturing.
- Support test hardware qualification and troubleshooting (probe cards, load boards, sockets).
- Prepare and maintain test documentation, validation reports, and release artifacts; support audits and quality reviews.
Qualifications
- Bachelor’s degree in Electrical Engineering, Electronics Engineering, Semiconductor Technology, or a related field.
- 2+ years of experience in semiconductor device testing, validation, or test development.
- Hands-on experience with Automated Test Equipment (ATE) such as Teradyne, Advantest, Verigy, or similar platforms.
- Strong understanding of semiconductor fundamentals, analog and digital circuits, and IC testing methodologies.
- Experience analyzing test data using tools such as Excel, JMP, Python, or MATLAB.
- Working knowledge of wafer probing, test hardware, and manufacturing test flows.
- Experience with Design for Test (DFT), scan, BIST, boundary scan, or ATPG is a plus.
- Programming or scripting experience (C/C++, Python, Perl, or similar) is desirable.
- Familiarity with yield analysis, SPC, and high-volume manufacturing environments.
- Strong analytical, problem-solving, communication, and technical documentation skills.
Soft Skills & Expectations
- Strong problem-solving and analytical mindset.
- Ability to work independently while managing multiple priorities.
- Clear communication of technical findings to engineering and manufacturing teams.
- Comfortable working in a fast-paced, data-driven semiconductor environment.
