Patent number: 5946563Abstract: There are provided: an isolation protruding upward from a semiconductor substrate in an active region; a gate electrode formed in the active region; and a pair of dummy electrodes formed to extend over the active region and the isolation and substantially in parallel with the gate electrode. Each of the gate electrode and dummy electrodes is composed of a lower film and an upper film. The lower films of the dummy electrodes are formed flush with the isolation and in contact with the side edges of the isolation. With the dummy electrodes, any gate electrode can be formed in a line-and-space pattern, so that the finished sizes of the gate electrode become uniform. This enables a reduction in gate length and therefore provides a semiconductor device of higher integration which is operable at a higher speed and substantially free from variations in finished size resulting from the use of different gate patterns.Type: GrantFiled: June 23, 1997Date of Patent: August 31, 1999Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Takashi Uehara, Toshiki Yabu, Mizuki Segawa, Takashi Nakabayashi, Minoru Fujii

Semiconductor device having polysilicon electrode minimization resulting in a small resistance value
Patent number: 5726479Abstract: A polysilicon electrode is formed in an active area surrounded by an isolation on a silicon substrate with a gate oxide film sandwiched therebetween, a polysilicon wire is formed on the isolation, and a source/drain region is formed on both sides of the polysilicon electrode. On the both sides of a polysilicon film constituting the electrode and the wire are formed side walls having a height that is 4/5 or less of the height of the polysilicon film. Furthermore, the polysilicon film is provided with a silicide layer in contact with the top surface and portions of the side surfaces of the polysilicon film projecting from the side walls, and another silicide layer is formed in contact with the source/drain region. Since the sectional area of the silicide layer is increased, the resistance value can be suppressed even when the dimension of the polysilicon film is minimized. Thus, the invention provides a semiconductor device including an FET having a low resistance value applicable to a refined pattern.Type: GrantFiled: January 11, 1996Date of Patent: March 10, 1998Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Michikazu Matsumoto, Minoru Fujii, Toshiki Yabu -

Patent number: 5500379Abstract: In a CMOS semiconductor device, low-dose ion implant of p-type impurity and n-type impurity is successively conducted to both n-MOSFET and p-MOSFET after formation of gate electrodes. Thereafter, when source/drain regions are formed at each MOSFET, p.sup.- regions function as local punch through stoppers in the n-MOSFET and n.sup.- regions function as the local punch through stoppers in the p-MOSFET. At this time, respective doses of n-type and p-type impurities are adjusted so that lowerings of threshold values of the channel regions are almost equal to each other. Thus, short channel effect is prevented, while reducing the step of forming two resist masks. With side walls, the CMOS semiconductor device with less short channel effect and high durability to hot carrier is manufactured without increase in the step of forming the resist masks.Type: GrantFiled: June 24, 1994Date of Patent: March 19, 1996Assignee: Matsushita Electric Industrial Co., Ltd.Inventors: Yoshinori Odake, Teruhito Ohnishi, Minoru Fujii

Patent number: 4328843Abstract: Reusable pressurized containers are disclosed for dispensing fluids from the container without release of the pressurized propellant to the surrounding environment. The propellant is contained in a sealed, flexible compartment positioned within the container as a mixture of gas and liquid under pressure in equilibrium at the temperature of the container. A pressure transfer liquid, such as water, is used to liquefy the propellant in the compartment. The pressure transfer fluid also contacts the fluid or semi-solid to be dispensed and exerts pressure thereon to force the fluid to be dispensed out of the container. The liquefied propellant, as it vaporizes, maintains the pressure against the pressure transfer fluid essentially constant. The propellant in the flexible compartment is preferably a mixture of a liquefiable propellant gas or blend thereof and a nonliquefiable inert gas such as nitrogen or helium.Type: GrantFiled: January 11, 1980Date of Patent: May 11, 1982Inventor: Minoru Fujii
