Latest Patents

Among his latest patents is a groundbreaking invention related to semiconductor local interconnect and contact. This patent describes an integrated circuit that includes a gate dielectric and a gate positioned on and over a semiconductor substrate. A junction is formed adjacent to the gate dielectric, and a shaped spacer is created around the gate. Additionally, a spacer is formed under the shaped spacer, and a liner is established beneath the spacer. The invention also details the formation of a first dielectric layer over the semiconductor substrate, the shaped spacer, the spacer, the liner, and the gate. A second dielectric layer is then formed over the first dielectric layer, with a local interconnect opening created in the second dielectric layer down to the first dielectric layer. This opening exposes the junction in the semiconductor substrate and the first gate, which are subsequently filled with a conductive material. Another notable patent focuses on reliable interconnects, presenting a method for forming a semiconductor device. This method involves providing a substrate prepared with a dielectric layer that has a conductive line in its upper portion. The substrate is processed to create a top surface of the dielectric layer that is not coplanar with the top surface of the conductive line, resulting in a stepped topography.
