Latest Patents

Dirk Schumann holds a patent for a "Method for producing a CMOS circuit." This patent describes a process in which an n-channel MOS transistor and a p-channel MOS transistor are formed in a semiconductor substrate. The method involves the formation of in situ p-doped, monocrystalline silicon structures through selective epitaxial growth. These structures serve as a diffusion source for creating source/drain regions of the p-channel MOS transistor. The source/drain regions of the n-channel MOS transistor are produced beforehand using implantation or diffusion techniques. The selectivity of the epitaxy used in this method eliminates the need to cover the n-doped source/drain regions during the production of the p-channel MOS transistor.
