Introduction

Sheng-Wei Tsao is a notable inventor based in Yun-Ho, Taiwan. He has made significant contributions to the field of semiconductor technology, particularly in memory arrays and field effect transistors. With a total of 2 patents, his work has advanced the capabilities of memory devices.

Latest Patents

One of his latest patents is for a memory array with byte-alterable capability. This invention provides a memory array that supports signals and a method for byte access for programming, erasing, and reading memory cells. The advantage of this array and method is the ability to access bytes for program, erase, and read operations. This array and method utilize an added isolation transistor to isolate the high voltage from the unselected byte. Additionally, it employs a separate source line for each byte in a row, which is also shared by a byte in a different row. The array has minimal peripheral circuit overhead requirements and avoids programming disturbances of unselected memory cells.

Another significant patent is for a vertical split gate field effect transistor (FET) device. This invention includes a method for fabricating the split gate FET device, which is formed within a semiconductor substrate. A trench is created within which the sidewall fully contains a channel region of the split gate FET device. A floating gate electrode is formed within the trench, covering a lower sub-portion of the channel region. The control gate electrode is formed vertically and horizontally overlapping the trench, covering an upper sub-portion of the channel. This split gate FET device is fabricated with enhanced areal density and improved performance.
