Title: Oxide film removing method of wafer surface
Inventor: YUN HYUN-SOO
IPC: H01L21/302
Filed: 1993-08-18
Granted: 1996-09-23
Abstract: The method for removing natural oxide film or thermal oxide film on the wafer(13) surface prior to the formation of polysilicon comprises following stages: a first stage; throwing a wafer in a reaction furnace(11) after cleaning, pumping slowly by operating vacuum pump(P2), a second stage; ionizing CF4 gas by way of a plasma generator, introducing the CF4 gas into the reaction furnace, and then removing the oxide film by reacting the oxide film with gas, whereby reducing a contact resistance and current leakage during the vapor deposition of the polysilicon on the wafer surface.

Granted: 1997-04-12
Abstract: An electric field reflected between a door plate(40), a door screen(41) and a front panel(20) is absorbed by a high frequency absorber(30). As a means of connecting the high frequency absorber(30) through a hole(22) in a front panel(20), a flange(23) which has an inserting hole(24) is prepared. After inserting the high frequency absorber(30) into the hole(22) of the front panel(20) by simply inserting a latch(31) of the high frequency absorber(30) in the inserting hole(24), high frequency absorber(30) can be fixed firmly with the front panel(20). As a high frequency absorber(30) a mixture of ferrite which has outstanding high frequency absorbing power and heat proof plastic are used.

Title: A new thin film transistor structure for increasing storage capacitance in the pixel element
Inventor: HAN MIN-KOO
IPC: H01L29/772
Filed: 1993-10-14
Granted: 1997-01-11
Abstract: There is provided a liquid crystal display in which a picture is constructed of pixel devices each of which includes a source node serving as a predetermined liquid crystal node. The pixel device includes a voltage line connected to a predetermined voltage supply, a first switching transistor, connected to the voltage line, for forming a current path between a predetermined data line and the liquid crystal node, and second switching transistor, connected to the voltage line, for forming a current path between the data line and liquid crystal node. Accordingly, the pixel device whose current driving performance and capacitance increase is provided to speed up the charging time of current at the source node.
