Title: Innovations of Chong Wee Lim
Introduction
Chong Wee Lim is a notable inventor based in Misia, Malaysia. He has made significant contributions to the field of semiconductor technology, holding a total of 8 patents. His work primarily focuses on improving the fabrication processes of sub-micron devices.
Latest Patents
One of his latest patents is the "Silicon nitride capped shallow trench isolation method for fabricating sub-micron devices with borderless contacts." This innovative process enhances the fabrication of MOSFETs in shallow trench isolation (STI) with sub-quarter micron ground rules. The method incorporates a passivating trench cap layer of silicon nitride, which is crucial for forming borderless or "unframed" electrical contacts without compromising the poly to poly spacing. The selective etch process utilized during the contact hole opening ensures that the passivating silicon nitride trench cap layer remains intact, thereby protecting the P-N junction at the edge of the trench region. This advancement improves device reliability by preventing electrical short circuits and reducing overall diode leakage. Additionally, the silicon nitride trench cap safeguards the underlying STI trench oxide during cleaning processes and minimizes transistor junction leakage.
