Latest Patents
Chiou's latest patents focus on methods for stress tuning to reduce wafer warpage. One of his notable inventions involves a method that includes forming a low-k dielectric layer over a substrate of a wafer. This process entails creating a first dielectric layer over the low-k dielectric layer, followed by a second dielectric layer. A stress tuning dielectric layer is then formed over the second dielectric layer, which includes an opening to expose the top surface of the second dielectric layer. The etching of the stress tuning dielectric layer and the second dielectric layer is performed in separate steps. The method further includes etching the first dielectric layer to create a via opening connected to the trench, ultimately filling the trench and the via opening to form a metal line and a via.
Another patent describes an integrated circuit structure that includes a substrate and multiple low-k dielectric layers. A first dielectric layer is placed over these layers, with a metal line embedded within it. The stress tuning dielectric layer is positioned above the first dielectric layer and features two openings. The metal line extends into one of these openings, while the second opening is designed to be level with the top surface of the first dielectric layer.
