Senior Polymer Materials Engineer

Date: Apr 10, 2018

Location: Taichung, TXG, TW

Company: Micron


Req. ID: 100325 

As a Senior Polymer Materials Engineer you will develop and characterize packaging materials for advanced packaging technologies to ensure manufacturability, quality and reliability targets are met. Key focus will be on materials to enable NAND and DRAM memory package devlopment.  You will be responsible for creating material technical roadmaps.  You will be responsible for coordinating assembly of materials test vehicles for testing and evaluating results to provide recommendations for materials specifications and process limits, as necessary.  Close collaboration with multiple engineering teams in development, process, design, and quality is required. 



  • Create and maintain material technical roadmaps for communication internally and externally
  • Document critical to function requirements for design rules, controlled design documents, procurement specifications, and supplier PFMEA/QCP
  • Participate in on-site technical assessments of suppliers as needed and provide technical input to internal business partners on supplier ratings & sourcing strategies; representing APTD on the key material groups (KMG) used for establishing global strategies for Polymer Materials
  • Coordinate characterization testing to gather data to ensure materials & processing interaction effects are accounted for when integrating materials with packaging technology
  • Define material characterization plans for new packaging technologies taking into account chip-package-interaction (CPI) effects
  • Document primary material related package wear-out failure modes and failure mechanisms under various stress conditions to ensure characterization testing covers intrinsic reliability performance
  • Drive useful life modeling of failure mechanisms in the expected application environments based on known acceleration model algorithms and experimentally derive physical constants as needed for primary material related wear-out failure mechanisms
  • Participate in technology risk assessments for new packages and packaging technologies and provide recommendations to mitigate risk profile
  • Identify and introduce materials for new package construction, process, yield and reliability improvement
  • Participate in engineering teams to evaluate new material and develop process for the new material and new package construction, and integrate the material into final product
  • Resolve packaging material related qualification and production issues using package failure analysis techniques

Successful candidates must have:

  • Experience in polymeric packaging materials (EMC, DAF, FOW, underfill, NCF, SR etc.), fabrication technology, and supplier assessments
  • Hands-on experience of major materials characterization tools (e.g. DMA, TMA, DSC etc.) is a plus
  • Knowledge of material related failure mechanisms, chip-package interactions, reliability testing, and reliability modeling is preferred
  • Demonstrated knowledge of how key materials are fabricated; examples of key materials are mold compounds, die attach films or pastes etc.
  • Understanding of IATF16948 requirements and ability to critically assess supplier health in areas such as APQP, PFMEA, QCP, MSA, & PPAP. 
  • Excellent problem solving and analytical skills
  • Detailed understanding of physical failure analysis methods
  • Strong data analysis, SPC, DOE skills
  • Strong communication skills (verbal and written)
  • Process auditing experience is preferred


Minimum Degree required:

  • MS or equivalent


Academic Discipline(s):

  • Materials Engineering, Materials Science Engineering, Chemical Engineering


Experience Required:

  • Minimum 5 years with advanced degree, >10 years experience preferred
