Latest Patents
One of Yu Cheng Tung's latest patents is titled "Semiconductor device with shallow trench isolation having multi-stacked layers and method of forming the same." This invention involves a semiconductor device that includes a substrate and at least one trench located at the top surface of the substrate. The device features a first dielectric layer, a second dielectric layer, and a third dielectric layer that are sequentially stacked on the inner wall of each trench. The design ensures that the topmost surface of the first dielectric layer is lower than that of the second dielectric layer and the substrate's top surface, creating a groove that enhances the device's reliability. The fillet structure at the edge corner of the trench is smooth and round, which reduces point discharge and improves the overall performance of the shallow trench isolation structure.
Another notable patent by Yu Cheng Tung is also focused on shallow trench isolation structures and semiconductor devices. This patent shares similar features with the previous one, emphasizing the importance of the dielectric layers and the trench design in enhancing device reliability.
