Latest Patents

Wang's latest patents include a novel fabricating method of a flash memory cell. This invention features a flash memory cell that comprises a first conductive type substrate, a second conductive type well, a patterned film layer, a second conductive type doped region, a tunneling dielectric layer, a plurality of floating gates, an inter-gate dielectric layer, and a plurality of control gates. The design allows for the floating gates to be formed on the first conductive type substrate outside the patterned film layer, with a thickness greater than that of the patterned film layer. This innovation increases the overlapping area between the floating gates and the control gates, thereby enhancing the coupling ratio of the flash memory cell.

Another significant patent by Wang is related to a flash memory cell and its manufacturing method. This invention includes a p-type substrate, an n-type deep well, a stacked gate structure, a source region, a drain region, a p-type pocket doped region, spacers, a p-type doped region, and a contact plug. The n-type deep well is established within the p-type substrate, and the stacked gate structure is positioned over the p-type substrate. This design optimizes the arrangement of the source and drain regions, contributing to improved performance in flash memory applications.
