His work is primarily associated with Winbond Electronics Corporation, where he continues to push the boundaries of technology.

Latest Patents

Wang-Ta Li's latest patents include a manufacturing method of a memory device. This method involves several steps, starting with the formation of a gate stacking structure over a substrate. A first insulating layer, a second insulating layer, and a mask material layer are sequentially formed to cover the gate stacking structure. An ion implantation process is then performed on the mask material layer to create a doped portion that caps the top of the gate stacking structure. Following this, a first patterning process uses the doped portion as a shadow mask to remove the bottom portion of the mask material layer. Finally, a second patterning process removes the doped portion and the exposed bottom portion of the second insulating layer surrounding the gate stacking structure.

Another patent focuses on a memory device and its manufacturing method. This device includes a gate stacking structure, a first insulating layer, a second insulating layer, and a first spacer. The gate stacking structure is positioned over a substrate, with the first insulating layer covering its top surface and sidewall. The second insulating layer covers the first insulating layer, while the first spacer is located on the sidewall of the gate stacking structure, ensuring that its topmost end is lower than the topmost surface of the second insulating layer.
