Title: Innovations of Inventor Hong Liao
Introduction
Hong Liao is a prominent inventor based in Singapore, SG. He has made significant contributions to the field of semiconductor technology, holding a total of 16 patents. His work focuses on advanced methods of fabricating memory devices, which are crucial for modern electronics.
Latest Patents
Among his latest patents is a method of fabricating floating gates. This method involves providing a substrate divided into a cell region and a logic region. A silicon oxide layer and a silicon nitride layer cover these regions. Numerous shallow trench isolations (STIs) are formed in the silicon nitride layer, the silicon oxide layer, and the substrate. The silicon nitride layer within the cell region is then removed to create a recess between adjacent STIs, while the layer in the logic region remains intact. A conductive layer is subsequently formed to fill the recess, which is then thinned to create a floating gate. Another notable patent is for a light-erasable embedded memory device and its manufacturing method. This device includes a substrate with a memory region and a core circuit region, featuring a floating gate on the memory region. It also incorporates at least two light-absorbing films above the floating gate, each with dummy via holes overlapping the gate, and a dielectric layer that fills these holes.
