Title: Semiconductor device having desired gate profile and method of making thereof
Inventor: KIM MIN
IPC: H01L27/115
Filed: 2000-09-14
Granted: 2003-11-11
Abstract: In a method of manufacturing a non-volatile memory or other semiconductor device, a control gate made of conductive material is formed in a more uniform fashion. The method includes forming a silicon layer on a buffer oxide layer on a semiconductor substrate. After forming the buffer oxide layer, a stopping layer is formed. The control gate of conductive material, such as a floating gate in an EEPROM memory device, is provided by patterning the silicon layer, gate oxide layer, and the substrate, and then, a trench is formed in the upper portion of the substrate. Uniformity is achieved by oxidizing the sidewalls of the trench to create bird's beaks at both upper and lower portions of the control gate material. Then, a field oxide layer that fills up the trench is formed. Because bird's beaks are evenly formed at both upper and lower portions of the control gate material during oxidation of the sidewalls of the trench, it is formed in a more uniform fashion since achieves uniformity is attained by preventing the sidewalls of the floating gate, for example, from having positive slopes.

The present invention comprises an LCD panel, a gate driver, a data gray signal modifier and a data driver, and generates modification gray signals by considering m-bit gray signals of present and previous frames among the n-bit gray signals received from a data gray signal source and supplies the generated modification gray signals to pixels so as to improve response characteristics of the LCD. According to the present invention, pixel voltages directly reach desired target level without frame delays. Hence, the liquid crystal response speed can be improved without changing a configuration of a TFT-LCD panel. Further, by using the m bits of the gray signals, the number and capacity of the memory needed for modification of the data voltage can be reduced, thereby improving panel yield and reducing the cost.
