About the Job

Requirements

  • Hands-on experience evaluating, processing, and/or successfully qualifying at least two advanced packaging dielectrics, such as ABF, PBO, PSPI, PID, solder resist, or BCB.
  • Deep knowledge of dielectric patterning approaches: photoexposure, development, and cure sequences for photosensitive materials, or lamination and laser drilling for non-photosensitive films.
  • Extensive experience with film characterization methods, including ellipsometry, FTIR, TGA/DSC, profilometry, and nanoindentation.
  • Understanding of dielectric-to-metal adhesion, CTE mismatch, and stress management in multilayer stacks.
  • Experience with electrical characterization of dielectric films, including Dk, Df, leakage, and breakdown voltage.
  • Ability to execute reliability testing per JEDEC standards, including HAST, uHAST, and TCT, and interpret failure mechanisms.
  • Fluency in English.

Responsibilities

  • Evaluate, down-select, and integrate advanced packaging organic and polymeric materials across material selection, film deposition or lamination, patterning, and cure characterization.
  • Oversee evaluation of material performance through reliability testing and collaborate with downstream assembly teams to understand incoming assembly requirements.
  • Characterize dielectric film electrical, thermal, and mechanical properties and correlate them with process and reliability outcomes.
  • Select, qualify, and support process-window definition for advanced packaging dielectrics, such as ABF, PBO, PSPI, polyimide, and inorganic films, for RDL build-up.
  • Support determination of optimal processing conditions for these materials across process teams critical to the fabrication process flow.
  • Evaluate emerging dielectric materials and technologies, such as low-Dk/Df and glass-core-compatible systems, for roadmap fit.
  • Develop and optimize cure, lamination, or photopatterning sequences for novel dielectric layers under evaluation.
  • Investigate and resolve adhesion, delamination, cracking, or CTE-mismatch failures through materials and process analysis.
  • Run reliability qualification testing, including HAST and TCT, and interpret dielectric-driven failure mechanisms.

Desired Qualifications

  • Proficiency in Korean.
  • Direct experience with glass-core or glass-interposer dielectric process integration.
  • Familiarity with low-Dk/low-Df materials for high-frequency and AI/HPC applications.
  • Knowledge of plasma-enhanced CVD or PVD inorganic dielectrics for thin-film packaging.
  • Experience with CMP of dielectric films in damascene or hybrid-bonding contexts.
  • Background in failure analysis of dielectric delamination, cracking, or via integrity using FIB-SEM, TEM, or laminography.
  • Familiarity with JEDEC and IPC qualification standards for substrate dielectrics.
  • Track record of material supplier engagement and collaboration on material testing and qualification.
  • Publication record or patent activity in dielectric materials for packaging.

About the Company

Absolics

Makes glass substrates for semiconductor packages

Absolics develops glass substrates and advanced packaging technology for semiconductor businesses building high-performance computing and AI systems. A substrate forms the base that connects processing and memory chips within a single package, linking the separate parts of a complex computing system. Its glass-core approach is designed to support smaller, more densely packed connections and shorter electrical paths. The company is developing glass panels for supply to advanced semiconductor packaging customers, with related technologies for embedding components and managing heat. Established in 2021, Absolics is headquartered in Covington, Georgia.
