Latest Patents

Yoshigoe holds a patent for a method of etching a back layer on a substrate. This patent describes an intermediate layer formed on a portion that becomes a projecting section of a step difference on a semiconductor substrate. A layer to be polished, which has a slower polishing rate than the intermediate layer, is created to cover the intermediate layer and fill the recessed portion of the step difference. The process includes polishing over the area from this layer to the intermediate layer. Additionally, a stopper layer with a slower polishing rate than the layer to be polished can be formed under the intermediate layer. The polishing process utilizes fluctuations in the rotational torque of the polishing machine or interference colors to detect the endpoint of polishing.
