Title: Liquid crystal display device and driving method thereof
Inventor: NAGAYAMA KOHEI
IPC: G09G3/20
Filed: 2001-11-19
Abstract: PROBLEM TO BE SOLVED: To provide a liquid crystal display device which shows no flickers both in use of reflection- or transmission-type display. SOLUTION: When a backlight 15 is turned on by a lighting circuit, the potential of a counter electrode 33 is decreased by a potential change-over circuit. Flickers are eliminated by equalizing the positive and negative polarities of the AC voltage of a transparent electrode 24 to symmetrize the voltage to be applied to a liquid crystal layer 5. When the brightness of the backlight 15 is increased so that the light transmitting the transparent electrode 24 is sufficiently brighter than the light reflected by the metallic electrode 25, the flickers of the metallic electrode 25 are made inconspicuous. When the backlight 15 is not turned on, the potential of the counter electrode 33 is increased by the potential change-over circuit.  The flickers are eliminated by equalizing the positive and negative polarities of the AC voltage of the metallic electrode 25 to symmetrize the voltage to be applied to the liquid crystal layer 5. When the backlight 15 is not turned on, the flickers are invisible because no light is transmitted through the transparent electrode 24.

Title: Superconducting wiring and its forming method
Inventor: SHOJI AKIRA
IPC: H01L39/24
Filed: 2001-11-21
Abstract: PROBLEM TO BE SOLVED: To solve the problem when an S/N/S type Josephson junction 12 is produced using a superconducting material NbN (niobium nitride)/normal resistance TiN (titanium nitride)/superconducting material NbN (niobium nitride) that a break of crystal 13 appears in the niobium nitride wiring 9 at the corner of a step in the junction 12 or an interlayer insulation layer 10 and current flow is retarded significantly. SOLUTION: Since a wiring is formed not by planarizing a previously deposited insulator, e.g. silicon oxide, but by planarizing the wiring itself, not only the protruding parts but also the recessed parts are planarized simultaneously. When a wiring having a sufficient film thickness has been deposited previously, end point detection is not required and since the process is simplified, yield of the process is enhanced.
