Besi Improved Memory Chip Manufacturing with Multiphysics Simulation

Stefan Behler, Besi, Switzerland

As memory chips become smaller and smaller, designers must ensure that the chips stay intact during the manufacturing process. Besi develops equipment and assembly processes for substrate and wafer packaging production in markets such as consumer electronics, automotive, industrial, and solar energy. Stefan Behler, a senior expert process engineer, used multiphysics simulation to explore and optimize a new way of peeling off the tape on a memory chip that results in less deformation of the dies. This new method is now used by semiconductor packaging factories all over the world.
