Test Engineer-Semiconductor

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.
