Title: Innovations by John P Phipps
Introduction
John P Phipps is a notable inventor based in Phoenix, AZ, with a significant contribution to the field of semiconductor technology. He holds a total of 7 patents, showcasing his expertise and innovative spirit in developing advanced semiconductor devices.
Latest Patents
Among his latest patents is a method for making a semiconductor device that features a high energy sustaining capability. This invention integrates a plurality of temperature compensated voltage reference diodes between the drain and the gate of the semiconductor device. The diodes serve to protect the device by clamping its sustaining voltage to the total avalanche voltage of the diode. This design allows the device to dissipate excessive energy in conduction mode rather than in the more stressful avalanche mode. Additionally, the arrangement of diodes provides a temperature compensated sustaining voltage, with the diodes formed back-to-back in polysilicon. The positive temperature coefficient of the avalanching junction of each diode pair is compensated for by the negative temperature coefficient of the forward biased junction.
Another significant patent involves a method of testing a semiconductor device that has a first circuit. This method facilitates testing by forming the semiconductor device to have a first portion that is electrically isolated from a second portion. Testing is initially performed on the first portion of the semiconductor device, and once completed, the first portion is electrically coupled to the second portion.
