AST

About Advanced Substrate Technologies Pte. Ltd.

We are a Singapore-based subsidiary of TOPPAN Holdings Inc., a Japanese pioneer in printing technologies and a leading supplier of high-quality Flip Chip Ball Grid Array (FC-BGA) substrates. We are the first factory in Singapore to pioneer the manufacturing of high-end FC-BGA substrates used in cutting-edge semiconductor products such as network switches and artificial intelligence (AI)/machine learning (ML) devices.

Additionally, our facility will conduct research and development (R&D) aimed at advancing substrate technologies to meet the evolving performance requirements of future products in these domains. Broadcom Inc., a global technology leader specializing in semiconductor design, enterprise software, and security solutions, is also actively supporting the establishment of this state-of-the-art manufacturing facility in Singapore.

 

Resposibilities

Process Development & Optimization                  

  • Develop and refine CMP processes for planarizing dielectric and metal layers (e.g., copper, dielectric, etc.) in advanced substrate manufacturing.
  • Optimize polishing recipes, pad/slurry combinations, and process parameters to achieve planarity, low defectivity, and target thickness.

Equipment & Tooling Support                   

  • Define equipment specifications and validate CMP tools.
  • Monitor and maintain CMP tool performance, including pad conditioning, slurry delivery systems, and endpoint detection technologies.

Yield & Quality Improvement                     

  • Investigate and resolve CMP-related defects (e.g., dishing, erosion, scratching, delamination).
  • Implement process monitoring techniques like thickness metrology (e.g., ellipsometry, profilometry) and defect inspection.

Process Integration 

  • Collaborate with upstream and downstream process owners (e.g., plating, lithography, etching) to ensure seamless integration.
  • Support the development of process flows for advanced packaging substrates including SAP/ Damascene, ABF/PI/PID-based technologies.

Data Analysis & Documentation

  • Perform statistical analysis (e.g., DOE, SPC) to identify and control critical process parameters.
  • Document standard operating procedures (SOPs), work instructions, and control plans.

Cross-Functional Collaboration

  • Work closely with design, product engineering, equipment vendors, and manufacturing teams to support process scale-up and new product introduction (NPI).
  • Assist with customer qualifications and reliability testing as needed.

Perform any other ad-hoc duties as assigned by the Manager, as required to support the team and organizational goals. 

 

Location & Commitments

  • Premises located in 9 Pesawat Drive, Singapore 619607
  • Permanent, full-time role working 40 hours per week

 

Job Requirements

Professional Qualifications:

  • PhD or Master’s degree in Materials Science, Chemical Engineering, Mechanical Engineering, or a related field.
  • 5–10+ years of experience in CMP process development in semiconductor packaging, wafer fabrication, or substrate manufacturing.
  • Hands-on experience with CMP tools.
  • Solid understanding of substrate technologies such as Damascene, SAP, ABF build-up, or Embedding.

Specialized Knowledge & Skills:

  • Experience with defect analysis tools (e.g., optical inspection, SEM, AFM).
  • Familiarity with process integration for advanced packaging (e.g., 2.5D/3D IC, interposers).
  • Knowledge of slurry chemistry, pad materials, and post-CMP cleaning processes.
  • Strong analytical, documentation, and problem-solving skills.
  • Good communication and teamwork in a cross-functional environment.
