In your new role you will:
- Lot assessment and disposition after wafer probing test and yield deviation analysis of production.
- Set up wafer stop limit (SBL and yield limit) for wafer probing test bins and define the scrap limit with Infineon internal team.
- Front End wafer probing yield monitoring and yield roadmap setup of BCD/RF products running in outsourcing wafer foundry.
- Co-work with Infineon EWM process integration and quality experts to improve processes to reduce production costs and increase yields for production.
- Be interface of wafer foundry and testing house, focal point for front-end process issues, low yield investigation & test parametric data analysis, support wafer probing yield assessments towards foundry process change and CIP/DOE lots as well as testing issue reduction for production.
- Co-work with internal technical team and external wafer foundry for root cause understanding of customer returns and final test failures of production.
- Work closely with the Infineon design team, product development team and test development team to solve yield problems before production(NPI stage).
- Support product release milestones and release both wafer probing testprogram and products from NPI stage to production as frond end product engineer role.
- Interface with internal and external customers to resolve technical issues requiring in depth product knowledge.
- Support wafer probing and final test specification alignment with Infineon internal experts.
You are best equipped for this task if you have:
- Min. Bachelor/Master Degree in Electronic Engineering or equivalent.
- Min. 4~7 years of working experience in Product Engineering, Test Engineering, or Device Engineering in the semiconductor field.
- In depth knowledge of BCD/RF/NVM products and processes.
- Knowledge of device fabrication process, such as Diff/IMP/CMP/Litho/Etch/CVD/PVD etc., including inline and electrical testing PCM items and their impact on device performance.
- Theoretical and practical knowledge of PN junction diodes, Schottky diodes, BJT, MOSFETs, capacitors, and resistors, etc.
- Good statistical knowledge (SPC).
- Experience with Mentor/Galaxy Examinator/ACE/PDF Exensio and JMP data analysis tools and Python/Tableau knowledge is desired.
- Excellent interpersonal, verbal, and written communication skills.
- Ability to demonstrate great attention to detail.
- Team player and self-motivated.
