Title: The Innovative Contributions of Vivian Ng
Introduction
Vivian Ng is a prominent inventor based in Singapore, known for her significant contributions to the field of semiconductor technology. With a total of 2 patents, she has made remarkable advancements in the manufacturing processes of nonvolatile memory devices.
Latest Patents
Her latest patents include a process to manufacture nonvolatile MOS memory devices and a nanocrystal flash memory device along with its manufacturing method. The first patent addresses the challenges associated with the conventional floating-gate devices by utilizing ion implantation. This innovative approach involves the initial use of rapid thermal oxidation to grow a high-quality layer of thin tunnel oxide, followed by chemical vapor deposition to deposit a germanium-doped oxide layer. The structure is then rapid thermally annealed to synthesize the germanium nanocrystals, resulting in superior data-retention characteristics.
The second patent presents a flash memory with a trilayer structure that includes rapid thermal oxide, germanium nanocrystals in silicon dioxide, and a sputtered silicon dioxide cap. This design has demonstrated memory hysteresis due to the presence of germanium nanocrystals in the middle layer, synthesized through rapid thermal annealing of a co-sputtered germanium and silicon dioxide layer.
