Title: Thomas William Edwards: Innovator in Semiconductor Technology
Introduction
Thomas William Edwards is a notable inventor based in Mount Joy, PA (US). He has made significant contributions to the field of semiconductor technology, holding a total of 3 patents. His work has advanced the manufacturing processes of thinned substrate imagers and reduced blooming devices, showcasing his expertise and innovative spirit.
Latest Patents
One of Edwards' latest patents is focused on the manufacture of thinned substrate imagers. This invention involves protecting the front surface of a semiconductor wafer and the peripheral edge of the back surface by either coating them or placing the wafer in a special fixture. The protected wafer is then placed in a chemical bath and thinned to the desired thickness over the entire center region of the back surface. A sheet of glass, which fits into the thin region within the unthinned rim on the back surface, is glued to the back surface to provide a laminated structure. The individual imager devices are subsequently separated by cutting through the glass and thinned substrate along lines between the devices.
Another significant patent by Edwards is related to reduced blooming devices. This invention includes a target for vidicons and image intensifier tubes that features a potential barrier less than about 1500 A from an input signal sensing surface. The targets also incorporate various passivation means for stabilizing the energy level configuration along the input signal sensing surface by substantially fixing the valence or conduction band along that surface relative to the Fermi level.
