Title: Niels Posthuma: Innovator in Semiconductor Technology
Introduction
Niels Posthuma is a prominent inventor based in Leuven, Belgium. He has made significant contributions to the field of semiconductor technology, particularly in the development of high electron mobility transistors (HEMTs). With a total of 7 patents to his name, Posthuma's work has had a substantial impact on the industry.
Latest Patents
One of his latest patents is a method of manufacturing a III-N enhancement mode HEMT device. This method involves providing a semiconductor structure that includes a substrate and a layer stack made of Group III-nitride material. A p-type doped GaN layer is placed on the layer stack, followed by a metal bi-layer that consists of a first metal layer in contact with the GaN layer and a second metal layer on top of the first, which has a lower sheet resistance. The method also includes a patterning process that aligns the peripheries of the metal layers and ensures that the cross-section of the metal bi-layer is smaller than that of the GaN layer.
Another notable patent relates to enhancement-mode high electron mobility transistors. This patent describes a method for manufacturing an enhancement-mode HEMT, which includes a stack of layers comprising a substrate, a III-V channel layer, a III-V barrier layer, a p-doped III-V layer, and a Schottky contact interlayer. The method emphasizes the importance of the surface areas of the layers, ensuring that the Schottky contact interlayer leaves a peripheral part of the p-doped III-V layer uncovered.
