Title: Resist material
Inventor: HASHIMOTO KAZUHIKO
IPC: G03F7/038
Filed: 1986-12-16
Abstract: PURPOSE:To obtain a resist material having high sensitivity and high-gamma by substituting deuterium for hydrogen in the molecules of a resist. CONSTITUTION:Methyl methacrylate used as a monomer is brought into an exchange reaction with heavy water (D2O) to completely substitute deuterium for hydrogen in the molecule. The monomer is polymerized in a sealed tube with azobisisobutyronitrile as a polymn. initiator to synthesize a polymer. This polymer is subjected to reprecipitation refining with a methanol-THF solvent, dissolved in methylcellosolve acetate and passed through a microfilter to filter off the insoluble matter. The resulting filtrate is used as a resist soln. This resist soln. is dropped on a silicon water, applied to the wafer by high-speed rotation, baked in an oven and radiated with electron beams at 20kV acceleration voltage. A positive type electron beam resist material having high sensitivity and high-gamma can be obtd.

Title: Semiconductor storage device and semiconductor device
Inventor: FURUYA KIYOHIRO
IPC: G11C8/08
Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor storage device which speedily operates with a low power consumption. SOLUTION: An internal power supply voltage Vint is generated by an n- channel MOS transistor 30 which operates in a source follower mode with an internal high voltage Vpp used, for example, for driving a word wire. When an internal circuit operates, the gate potential of the source-follower transistor 30 is boosted when an internal circuit operates, thus eliminating the need for using an exclusive internal high voltage generation circuit and increasing the conductance of the source-follower mode transistor 30 at the time of internal circuit operation.

Title: Method for inspecting leak of empty can or the like
Inventor: IKEDA TATSUMI
IPC: G01L11/00
Filed: 1998-10-08
Abstract: PROBLEM TO BE SOLVED: To provide a method for inspecting a leak of an empty can or the like with which a proper judgment through leak inspection with use of a pressure air can be maintained even if a pressure sensitive sensor becomes dull or is changed in sensitivity. SOLUTION: A chamber is divided via an object to be inspected to two chambers 4, 5 which can be tightly sealed. A pressure air is supplied to one chamber, and a pressure in the other chamber is measured by a pressure sensitive sensor 10, whereby the presence/absence of an air leak in the object W to be inspected is inspected. In the inspection method, in a state while the other chamber 4 is open to the air, an atmospheric pressure is measured by the pressure sensitive sensor 10, and moreover, the atmospheric pressure is measured again by the same pressure sensitive sensor immediately after the pressure air is supplied to the other chamber 5 and immediately before the supply is stopped. A difference of two measured values among three measured values is obtained and compared with a set predetermined pressure, thereby judging the presence/absence of an air leak in the object.  A deterioration range and a variation range of a heat sensitive element are offset by taking the difference of the plurality of measured values, so that a correct pressure difference can be detected.
