Latest Patents

One of Koops' latest patents focuses on trench-gate transistors and their manufacture. This invention describes a trench-gate transistor that features an integral first layer of silicon dioxide. This layer extends from the upper surface of the semiconductor body over the top corners of each cell array trench. It serves multiple purposes, including acting as a thin gate dielectric insulating layer for a thick gate electrode. Additionally, it forms part of a stack of materials that constitute a thick trench sidewall insulating layer for a thin field plate. The patent also outlines a method of manufacture, which includes the removal of a hardmask used to etch the trenches before applying the silicon dioxide layer. The layer is then protected through selective etching of the oxide and nitride layers in the upper parts of the trenches. After the gate electrodes are provided, layers for the channel accommodating regions and source regions can be formed through the oxide layer on the upper surface.
