Panasonic has developed a novel low-stress dielectric film (PLSF) for semiconductor packaging.
Polymers films with low stress are of importance to warpage control which is one of the key factors to fabricate Multi-chip Modules (MCMs) with
large body size.
A process flow for the demonstration of 5/5 μm L/S RDL fabrication  was developed in addition to demonstration of 7 μm microvia fabrication
using the Panasonic film.
This presentation will also include Warpage and residual stress of the PLSF characterization at various stages of fabrication along with
preliminary results of TCT.
