Title: The semiconductor memory device
Inventor: KOSINI YASUHIRO
IPC: G11C11/4076
Filed: 1986-10-16
Granted: 1990-04-21
Abstract: In a non-active cycle, the potentials of each pair of bit lines are precharged at half of a supply potential.  Each sense amplifier operates in an active cycle following the non-active cycle, while each active pull-up circuit pulls up the potential of a higher level in one of the pair of bit lines to Vcc.  This active cycle is defined by an internal signal, which is generated by a NAND circuit in response to external signals obtained by delaying the external signal by a delay circuit and having a trailing edge obtained by delaying the trailing edge of the external signal by a prescribed period.

Abstract: The removal of remnants formed at RIE (reactive ion etching) process and the restriction of damage on the silicon substrates by the collision of gas atoms are essential for the improvement of reliability of the device. To solve the problem, RTA process is treated during 1 to 5 minutes at 700 to 1100 deg.C under vacuum, O2, N2, inert gas, or their mixed ambience in order to repair the impurity penetration layers damaged by reactive ion etching and to remove the remnants (3) that compose of C-F or Cl polymer as shown in the figure, after RIE process. The property of silicon substrate is restored considerably by this method.

Title: Liquid crystal display devices having color seal
Inventor: KIM TAEK-SONG
IPC: G02F1/1337
Filed: 1991-12-23
Granted: 1994-05-19
Abstract: The device identifies a width, length, and position of wet state in a seal solution, and finds out a high-quality goods in the manufacturing works. The device etches a iTO(3) and prints out a liquid oriented layer (4) on a patterning glass (1), a seal liquid which contains a resin color adhesive printed on the patterning glass (1) and forms a gap which contains a crystal liquid (6). The device comprises a buthyl cellul solve 20 g, a bis phenol A type epoxy resin 50 g, bis phenol B type liquid crystal device 50 g, epoxy resin 40 g, and Al2O3 55 g. The size of iTO (3) is 350 x 300 mm. The wettimg width (W) of seal solution is 1.5 or 2.0 mm, and the wettimg height (H) is 30 - 50 μm.

Title: Voltage/current converter
Inventor: JU HO-KOL
IPC: H02M3/00
Filed: 1992-02-25
Granted: 1994-08-04
Abstract: a constant current supplying circuit having at least a pair of transistors connected to a first power voltage; a first current distributing circuit for forming a first current path and increasing or decreasing a current flowing into the first current path by an input voltage; and a second current distributing circuit for forming a second current path and linearly increasing or decreasing a current flowing into the second current path for the input voltage, thereby greatly improving output linearity of a voltage/current converter.

Title: Making method of resistor for semiconductor device
Inventor: KIM SONG-SHIK
IPC: H01L27/04
Filed: 1992-03-09
Granted: 1995-04-21
Abstract: The resistance in semiconductor device is prepared by (a) growing a 1st insulation film on the semiconductor substrate and forming a 2nd insulation film with an island shape on the resistance region, (b) forming the ring type polysilicon side wall in the 2nd insulation film side wall, (c) removing a certain part of polysilicon side wall and making the shape of this side wall to C letter type, (d) depositing the 3rd insulation film on all surface of the substrate and forming the contact holes at both ends of polysilicon sidewall, and the conductor on it.
