Role Description Role Summary The rapid expansion of RF in smartphones has positioned System Integrated Packaging and multi-die chiplet packaging as critical differentiators in semiconductor

manufacturing. We are seeking a highly capable Staff Engineer to be the technical authority

for our advanced molding and encapsulation modules. In this role, he will lead the development and high-volume manufacturing (HVM) scaling of mold encapsulation technologies designed to protect fragile silicon dies and fine-pitch interconnects from thermomechanical stress. Operating at the intersection of polymer chemistry, rheology, and mechanical engineering, you will drive breakthrough process solutions for next-generation advanced packaging.

Key Responsibilities

1)Process Development: Design, evelop, optimize, and transfer the mold processes recipes and post mold grinding process for strip based or unit based with multi-chip modules for both single sided or double sided mold configurations

2)Material Selection & Characterization: Evaluate and qualify advanced Epoxy Molding Compounds (EMC) to ensure environmental compliance (e.g. RoHS), will optimize material properties such as filler size, viscosity, cure kinetics, and coefficient of thermal expansion (CTE) to ensure compatibility with fragile silicon and minimize package warpage. He will create and optimize mold grinding recipes to balance customer requirements while preventing quality issues.

3) Yield & Defect Mitigation: Apply rigorous root cause failure analysis (RCFA) to identify and eliminate molding defects such as incomplete fill, voiding, interfacial delamination, resin bleed, and die cracking. You will utilize advanced metrology, including Scanning Acoustic Microscopy (C-SAM), X rays and cross-sectional analysis to drive effective defect detection and root cause analysis.

Tooling & Equipment Engineering: Drive the design and optimization of mold chases and tooling. You will program and calibrate state-of-the-art molding equipment, strictly controlling critical parameters such as clamping force, transfer pressure, vacuum levels, and dynamic cure temperature profiles.

Experimental Rigor & Scaling: Design and execute complex, multi-factor Designs of Experiments (DOE) to establish wide process windows implement Statistical Process Control (SPC) methodologies and define Control Plans and Process Failure Mode and Effects Analyses (pFMEAs) to improve early signal detection for sustainable quality controls.

Qualifications

• Strong knowledge of semiconductor packaging processes, especially molding, encapsulation, and related materials and equipment.
• 5+ years of hands on experience with process engineering, including DOE, statistical process control, and root cause analysis for yield and quality improvement.
• Familiarity with manufacturing operations, including production line support, equipment troubleshooting, and continuous improvement methodologies.
• Ability to interpret technical drawings, process specifications, and customer requirements in advanced packaging applications.
• Bachelor’s degree or higher in Engineering (e.g., Mechanical, Materials, Chemical, Electrical, or related field) or equivalent practical experience.
• Effective communication and collaboration skills, with the ability to work in cross-functional teams and a fast-paced production environment.
• Strong problem-solving mindset, attention to detail, and commitment to safety and quality standards.
• Prior experience in semiconductor manufacturing, advanced packaging, or assembly and test environments is highly beneficial.
• Willingness to work on-site in Penang and support occasional off-shift or weekend activities as required by production needs.
