Latest Patents

Bi-shen Lee holds a patent for a "Deep Trench Isolation (DTI) structure and methods for fabrication thereof." This patent describes a DTI structure that includes a composite passivation layer. The composite passivation layer consists of a hole accumulation layer and a defect repairing layer. The defect repairing layer is strategically placed between the hole accumulation layer and the semiconductor substrate, effectively reducing lattice defects at the interface. This reduction in defects leads to a lower density of interface traps, which facilitates strong hole accumulation and increases the flat band voltage. Additionally, the hole accumulation layer can be enhanced through an oxidation treatment, further improving the DTI structure's performance.
