Latest Patents

One of Scheerer's latest patents is focused on a bipolar transistor and the method for its production. This invention relates to NPN and PNP bipolar transistors characterized by a particularly high collector-emitter and collector-base blocking voltage. The blocking voltage is enhanced through a specific doping profile. The NPN bipolar transistor consists of a p-doped substrate, a trenched n-doped layer forming the collector, and a p-doped layer arranged above the trenched n-doped layer, which includes an emitter. The design allows for the expansion of spatial charge areas under increasing potential, ensuring high performance and reliability.

Another significant patent involves a method for fabricating a voltage-stable PMOSFET semiconductor structure. This method enables the creation of integrable PMOSFET structures in a P-doped substrate, distinguished by high dielectric strength. The process includes applying a mask to define a window on the semiconductor substrate, followed by high-voltage ion implantation to produce an N-doped well. This innovative approach results in a PMOSFET structure with enhanced dielectric strength due to the weak basic doping of the substrate.
