Latest Patent Applications

Ke-Gang Wen has filed several significant patent applications. One of his latest applications is for a "SEMICONDUCTOR DEVICE STRUCTURE AND METHODS OF FORMING THE SAME." This application describes a semiconductor device structure that includes a through silicon via disposed through a dielectric material, an interconnection structure, and a substrate. The design features a top surface of the through silicon via with a first diameter that is substantially greater than the second diameter located in the substrate. Additionally, the structure includes an alloy portion surrounding the through silicon via, a barrier layer surrounding the alloy portion, and a liner surrounding the barrier layer, all contributing to a funnel-shaped cross-section.

Another notable application is for an "Interconnect Structure for Front-to-Front Stacked Chips." This application discloses interconnect structures for front-to-front stacked chips and methods of fabrication. The exemplary system on integrated circuit (SoIC) includes a first die that is front-to-front bonded with a second die. This bonding is achieved by connecting the topmost metallization layers of both dies. The application also details a through via that extends partially through the first die's frontside multilayer interconnect, through a device layer, and through a backside power rail, which may be part of a backside multilayer interconnect.
