摘要： A digital driving circuit for a liquid crystal display which sequentially receives and displays n-bit digital video information from a data bus on a bit basis. The digital driving circuit comprises a first data latch for sequentially storing the digital video information from the data bus on a bit basis, a shift register for synchronizing a latching operation of the first data latch with bit positions of the digital video information from the data bus, a second data latch for storing the digital video information stored in the first data latch temporarily before digital/analog conversion, and a digital/analog converter for sequentially converting the digital video information stored in the second data latch into analog signals on a bit basis. The digital driving circuit is able to sequentially process bit information of digital video information to reduce the number of data bus lines for loading the bit information thereon and the number of data catches arranged vertically to a column direction. Therefore, the driving circuit can be significantly reduced in its occupying width, thereby making it possible to make the display higher in density.

摘要： The present invention relates to a method of forming a small gap using CMP and a method for manufacturing a lateral FED. In the present invention, a small gap is determined by the thickness of an oxide film, and so uniform small gaps of about 100 Å that have been impossible to attain with the art of prior lithography can be formed with repeatability. Prior lateral field emission devices have the problem of repeatability in forming a gap for field emission because they are fabricated by means of a thermal stress method or an electrical stress method. But if the method of forming a small gap according to the present invention is used to fabricate a lateral FED, a FED can be made that has low voltage drive and high current drive characteristics and uniform field emission characteristics.

摘要： A non-volatile static random access memory device configured by adding a floating gate type metal oxide semiconductor device to an SRAM including a pair of access elements respectively switched on and off in accordance with the state of a signal on an address line and adapted to establish a data transfer path between memory cell and associated negative and positive data lines, and a pair of inverters respectively coupled to the access elements, thereby allowing the SRAM to exhibit non-volatile memory characteristics. The floating gate type MOS device has a silicon substrate, a tunneling oxide film formed over the silicon substrate, a floating gate formed on the tunneling oxide film, an oxide film formed over the floating gate, a control gate formed over the oxide film, and a source and a drain respectively formed in an upper surface of the silicon substrate at both sides of the control gate. The source and drain of the floating gate type MOS device are electrically connected at the source and drain thereof to the input terminals of the inverters of the SRAM, respectively, so that it provides non-volatile memory characteristics to the SRAM by virtue of a difference in threshold voltage caused by charge stored in the floating gate thereof. This non-volatile SRAM device has a high density while exhibiting high-speed operation characteristics.
