SkyWater is hiring a
Mechanical Stress Simulation Staff Engineer to be responsible for executing advanced mechanical stress simulations for semiconductor advanced packaging, heterogeneous integration, and BEOL (Back-End-Of-Line) metallization layers. This role leverages industry-leading software tools to model, analyze, and optimize mechanical and thermal behaviors in complex semiconductor structures, ensuring reliability and performance across device, die, chip, and package levels.
Key Responsibilities:- Develop and execute multi-level mechanical stress models for semiconductor devices, circuits, dies, chips, and packaging.
- Simulate elastic, viscoelastic, and crack-related phenomena, including recoverable stress/strain, plastic deformation, delamination, and crack propagation, with direct impact on device performance and BEOL reliability.
- Utilize advanced simulation software such as ANSYS, TCAD Sentaurus, SInterconnect, and MultiPhysics Fusion to analyze mechanical stress, heat transfer, and dissipation in semiconductor packaging and BEOL layers.
- Plan test structures to characterize material properties (bulk modulus, shear modulus, coefficient of thermal expansion, binding strength) required for simulation and reproducing shortloop experiments.
- Collaborate with process integration teams to utilize simulation results in design and manufacturing workflows.
- Document methodologies, results, and recommendations for reliability improvements and yield enhancement.
Required Skills & Qualifications:- 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.
Preferred Experience:- Prior work in semiconductor industry, especially in packaging and BEOL.
- Knowledge of device performance impacts due to mechanical stress.
- Experience with characterization of material properties and shortloop experimental validation.
- Semiconductor technology integration experience
