Simulation in the semiconductor industry is evolving from a peripheral chip-design concern into a system-level competitive differentiator. As power density increases and advanced packaging becomes ubiquitous, thermal stress, warpage, and interconnect reliability have become decisive factors for product success.
Industry Characteristics
- Small dimensions but complex material systems
- Frequent thermal cycling with high interface failure risk
- Narrow design windows with sensitivity to process variation
Core Simulation Tasks
- Package warpage and residual stress analysis
- Life assessment of solder joints, bumps, and bonding structures
- Power device and substrate temperature rise analysis
- Thermal cycling and drop reliability verification
Engineering Recommendations
Package simulation should stay as close as possible to real process sequences—including reflow, curing, assembly, and thermal cycling. Otherwise, many problems remain invisible under idealized boundary conditions and only surface en masse during prototyping.
Deliverables
It is advisable to output warpage trend charts, critical interface lists, dominant life factors, and process sensitivity analyses, helping design teams quickly find the balance point among materials, structure, and process.
