Title: Innovations of David B Rensch
Introduction
David B Rensch is a notable inventor based in Thousand Oaks, California. He has made significant contributions to the field of semiconductor technology, holding a total of 13 patents. His work focuses on improving the performance and efficiency of power semiconductor devices.
Latest Patents
Among his latest patents is a method for the fabrication of high power semiconductor devices with integrated heat sinks. This innovative approach allows for a low-cost, highly integrated method of fabricating a heat sink on the backside of a power semiconductor device. It maintains device performance, improves thermal transfer, and enables reliable planar connections without the need to dice the wafer or package the discrete device-heat sink assembly. An etch stop layer is formed between the wafer and the frontside power devices to protect them during backside processing and to reduce contact resistance. The heat sinks are created by thinning, patterning, and plating the wafer, allowing for the devices to be released without dicing. The oversized heat sinks can be grasped by a vacuum tool, facilitating the compression bonding of the heat sink onto a planar microstrip circuit assembly, which is designed for easy replacement of failed devices.
