Latest Patents

Chao-Hsun Wang holds a patent for a "Contact formation method and related structure." This patent describes a method for forming a via-first metal gate contact. The process involves depositing a first dielectric layer over a substrate with a gate structure that includes a metal gate layer. An opening is created within the first dielectric layer to expose part of the substrate, followed by the deposition of a first metal layer within this opening. A second dielectric layer is then applied over both the first dielectric layer and the first metal layer. The etching of these layers results in a gate via opening that reveals the metal gate layer. The method further includes the removal of a portion of the second dielectric layer to create a contact opening that exposes the first metal layer. Ultimately, the gate via and contact openings merge to form a composite opening, allowing for the deposition of a second metal layer that connects the metal gate layer to the first metal layer.
