Abstract: An integrated circuit device is fabricated upon a semi-conductor wafer by first forming a stop layer upon the surface of the wafer. Holes are formed through the stop layer and wells are formed in the semiconductor material of the semiconductor wafer below the openings. A dielectric layer is formed over the surface of the device substantially filling the wells and covering the stop layer. The dielectric layer is then planarized to substantially the level of the stop layer. A PAD oxide layer is provided between the stop layer and the surface of the semiconductor device. Conventional thin film oxidation of the wells and implants into the side walls of the wells are performed. An abrasive mechanical polisher is used to perform the planarization wherein the mechanical polisher is provided with the self-stopping feature when it encounters the stop layer.

Abstract: A scheme to reduce output variations in a column driver for a flat-panel display by sharing the characteristics of analog circuit is disclosed. An input multiplexer is provided between two neighboring digital inputs, and an output multiplexer is provided between two neighboring analog outputs so that the characteristics of neighboring analog circuits can be shared by multiplexing. The averaging effect by sharing reduces variations in the output. The multiplexing may be done either in time division or on a frame-by-frame basis.

Abstract: A nonvolatile semiconductor memory device includes a plurality of floating gate type memory cell transistors having control gates. Word lines are integrally formed with the control gates, and boosting lines are self-aligned with the word lines. During programming, a first voltage is applied to a selected word line, and then a second voltage is applied to the boosting line over the selected word line. The voltage on the selected word line is then increased by capacitive coupling of the second voltage thereon, thereby programming at least one selected memory cell transistor. Therefore, a voltage lower than a program voltage is used on a selected word line, thereby reducing chip area and enhancing programming speed.
