Latest Patents

Among his latest innovations are the Metal-insulator-metal (MIM) capacitors. These capacitors feature a first capacitor electrode made of a first metal that extends on a substrate, along with a first electrically insulating layer. This layer has an opening that exposes part of the first capacitor electrode. An electrically insulating etch-stop layer, made from a different material, extends on the first insulating layer and also has an opening. A capacitor dielectric layer is then applied to the exposed portion of the first capacitor electrode and the sidewalls of the insulating layers. The second capacitor electrode, which can also be made of copper, gold, or aluminum, is positioned opposite the first electrode.

Another notable patent involves methods for forming integrated circuit capacitors with electrodes that include conductive plugs. This innovation aims to enhance the characteristics of capacitors and improve bit resolution, leading to more accurate analog devices. The design includes a conductive lower electrode on an insulating substrate, an insulating layer with a via hole, a dielectric layer, and a conductive upper electrode that forms a piled structure.
