Mechanical Stress Simulation Staff Engineer

Quick Facts

• Role: Mechanical Stress Simulation Staff Engineer

• Focus: Mechanical and thermal stress simulation for semiconductor advanced packaging and BEOL metallization layers

Description

Execute advanced mechanical stress simulations for semiconductor advanced packaging, heterogeneous integration, and BEOL metallization layers. Develop and run multi-level mechanical stress models to analyze and optimize elastic, viscoelastic, and crack-related phenomena that impact device performance and BEOL reliability. Use industry-leading software tools to improve reliability and performance across device, die, chip, and package levels.

Responsibilities

• Develop and execute multi-level mechanical stress models for semiconductor devices, circuits, dies, chips, and packaging

• Simulate elastic, viscoelastic, and crack-related phenomena (recoverable stress/strain, plastic deformation, delamination, crack propagation)

• Analyze mechanical stress, heat transfer, and dissipation using ANSYS, TCAD Sentaurus, SInterconnect, and MultiPhysics Fusion

• Plan test structures to characterize material properties (bulk modulus, shear modulus, coefficient of thermal expansion, binding strength) for simulation and shortloop experiments

• Collaborate with process integration teams to integrate simulation results into design and manufacturing workflows

• Document methodologies, results, and recommendations for reliability improvements and yield enhancement

Requirements

• Bachelor’s or Master’s degree in Mechanical Engineering, Materials Science, or a related field with 3+ years of related experience

• Experience with crack/delamination analysis and BEOL processes/materials

• Proficiency in finite element analysis (FEA) and simulation methodologies

• Hands-on expertise with mechanical simulation tools (ANSYS, Sentaurus, MultiPhysics Fusion, AutoCAD, SolidWorks)

• Familiarity with semiconductor packaging systems and BEOL materials

• Strong analytical, problem-solving, and communication skills

Benefits

• Competitive salary with potential participation in incentive plans

• 401k match and life insurance

• Comprehensive benefits starting day one: medical, dental, mental health, vision, legal planning

• Short- and long-term disability, paid time off, paid holidays

• On-site fitness facility and on-site self-serve market
