Title: Innovations of Peter Alexandrov

Introduction

Peter Alexandrov is a notable inventor based in Lawrence, NJ (US). He has made significant contributions to the field of semiconductor technology, particularly in the development of advanced junction field effect transistors (JFETs). With a total of three patents to his name, Alexandrov continues to push the boundaries of innovation in his field.

Latest Patents

One of his latest patents is the "Trench Vertical JFET with Improved Threshold Voltage Control." This invention involves creating trench JFETs by etching trenches into the topside of a substrate of a first doping type to form mesas. The substrate consists of a backside drain layer, a middle drift layer, and a topside source layer. The etching process penetrates through the source layer and partially into the drift layer. Gate regions are formed on the sides and bottoms of the trenches using doping of a second type. Vertical channel regions are created behind the vertical gate segments via angled implantation using a doping of the first kind, which provides improved threshold voltage control. Additionally, the substrate may include a lightly doped channel layer between the drift and source layers, enhancing the contrast with the implanted vertical channel regions.

Another significant patent is the "Trench Shield Connected JFET." This invention describes a shielded junction field effect transistor that features gate trenches and shield trenches, with the shield trenches being deeper and narrower than the gate trenches. The alignment of the gate trenches can be fully aligned, partially aligned, or separated from the shield trenches, showcasing the versatility of this design.
