Alexander F Spivak is a notable inventor based in Thousand Oaks, CA (US). He has made significant contributions to the field of pressure sensor technology. His innovative work has led to the development of a unique pressure sensor system that utilizes semi-conductive materials.

Latest Patents

One of his key patents is the linearity semi-conductive pressure sensor. This patent describes a pressure sensor system that features a semi-conductive diaphragm electrode positioned over a cavity in a semiconductor chip. The design includes a mesa that extends upwardly from the cavity, securing the center of the diaphragm. A second electrode is created by a heavily doped raised ring situated between the mesa and the chip's periphery, which is critical for the diaphragm's maximum deflection. The raised ring electrode is heavily doped with one polarity, while light doping is applied near the base of the raised area. The remaining cavity is heavily doped with the opposite polarity. The relationship between the width of the ring electrode and linearity error is explored, with the constructional features selected to align with the minimum point of the linearity function. Additionally, the reference capacitor is designed in an arcuate configuration, extending partially around the sensor diaphragm.
