Latest Patents

One of Seidel's latest patents is focused on the formation of multilayer dopant distributions in a semiconductor. This innovative method allows for the creation of solid-state devices with multilayer dopant distributions, including p-p+ and n-n+ junctions. The process involves rapidly melting a semiconductor body, typically using a laser, electron beam, or ion beam. During the rapid resolidification of the melt, a first dopant with a low segregation coefficient segregates toward the surface, while a second dopant with a high segregation coefficient remains in place, effectively producing a junction. This technique enables the production of various components such as diodes, bipolar and field effect transistors, Schottky barriers, and high conductivity paths.

Another significant patent by Seidel addresses metallization for integrated circuits. This patent describes a method to eliminate sharp features on metallization patterns defined by conventional etching processes. By utilizing instantaneous melting with short laser pulses, the method minimizes flow due to the brief molten state, while surface tension smooths out sharp corners. Additionally, this approach improves the conductivity of polysilicon metallization.
