Samsung Electronics The first successful ultra high transparency barrier material, which was commercialized by Vitex, was originally developed by GE in a process designed to be used for capacitor fabrication. This process is called the Polymer Multi-Layer (PML) process. It was developed in the late 1970's and early 1980's at GE's capacitor division in Hudson Falls, NY for the fabrication of multilayer, polymer/aluminum capacitors. By2011, most of the company's IP had been acquired by Samsung Samsung Electronics
