Micro Laser Annealing System

The Micro Laser Annealing (µLA) system irradiates a microbeam controlled area by a mask pattern to a specific position on the substrate. With the µLA system, thin films of minute area in the micro-meter order can be crystallized, activated, made highly dielectric, etc. without affecting the base substrate with heat.
