Title: Manufacture of semiconductor device
Inventor: SHIRAISHI MASATOSHI
IPC: H01L21/768
Filed: 1990-02-06
Abstract: PURPOSE:To realize high quality and reliability by a method wherein, after a window of contact is formed by isotropic etching, metal is deposited, the metal on resist is eliminated by lift-off, the metal is left only in the contact, and then BPSG flow is performed. CONSTITUTION:BPSG 2 is deposited on polysilicon 1 doped with phosphorus, and resist 3 is spread on the whole surface. For the purpose of isotropic etching, the aperture of the BPSG film 2 is formed so as to be larger than the pattern opened in the resist 3. After that, a natural oxide film on the polysilicon 1 doped with phosphorus is eliminated by using aqueous liquid of hydrofluoric acid. The resist 3 is eliminated by dipping the device in fuming nitric acid. At this time, tungsten 4 on the resist 3 is simultaneously eliminated, and left only inside the BPSG contact. Thereby wiring metal can be flattened, and high quality and reliability are realized.

CONSTITUTION:An area plan of a kitchen K is divided into a plurality of groups, wherein the connection between the kitchen K and a dining D is of a space type and the movement of a housewife in the kitchen K is a flow line plan, each of which is divided into a plurality of groups. Further the window shapes of the kitchen K are divided into a plurality of groups as a plan of opening. For example, the layout of the kitchen K and dining D is determined from a zoning plan of factor of closed type CL to decide a space type, flow line plan, and area plan. Next, a plan of opening of window is decided to decide an optimum plan out of matrix plans. By this method, the layout of a system kitchen is decided so that a salesman can easily give a plan including requirements of clients to designers.

Title: Method for driving solid-state image pickup device
Inventor: ASAUMI MASASHI
IPC: H04N5/335
Filed: 1993-02-16
Abstract: PURPOSE:To attain high speed reset of floating diffusion. CONSTITUTION:At first levels of phiH, phiR are set to high levels respectively to store a signal charge Q under a gate electrode 3 and to reset the potential of an impurity region 6. At that time lots of charges stored in the impurity region 6 are swept out to an impurity region 7 but untransferred charges QR remain. Then a drain voltage VRD of a reset transistor(TR) RT goes to a low level and the potential of the impurity region 7 is set lower than that of the impurity region 6. The potential of the impurity region 6 is fixed to a low level of VRD by the injection of the charge from the impurity region 7. Then the phiR goes to a low level and the impurity region 6 is in the floating state. Then the phiH goes to a low level, the signal charge under the gate electrode 3 flows to the impurity region 6 to change the potential of the impurity region 6. The change in the potential is outputted through a source follower circuit SF.

Abstract: PURPOSE:To obtain a microporous material having micropores of a fine and uniform diameter by compressing ceramics granular material having a pore diameter of about specific times that of a desired one and sterically bringing the particles into mutual contact. CONSTITUTION:This microporous material is obtained by regulating the diameter of ceramics grains to 3-300nm, the compressing pressure to 5000-40000atm and the diameter of pores to 1-100nm. In explanation in detail, ceramics particles having 3-300nm particle diameter and the uniform particle diameter distribution within the range of several to tens of % are used as the ceramics particles. If the ceramics particles are dispersed into a colloidal form in a solution, the dispersion is dried and pressurized under thousands of atom and temporarily formed into a cylindrical shape. The resultant temporarily formed ceramics particles are treated in a high-pressure pressurizing machine and pressurized under tens of thousands of atom to provide the microporous material. In the resultant porous material, the ceramics particles are kept in a steric close contact state and interstices formed among the ceramics particles are such that the pore diameter thereof in a closest packed state is [(1/4)(a)] to [(1/3)(a)] when the radius of the ceramics particles are (a).

Title: Method for granulating high softening point pitch into small-diameter pencil-like product
Inventor: MIYAZAWA JIYUNICHI
IPC: C10C3/14
Filed: 1981-02-26
Abstract: PURPOSE: To provide a small-diameter pencil-like product having high strength, by heating and melting high-softening point pitch and allowing it to flow down in the form of a small-diameter rod, to pass through a high-boiling point liquid and then to be cooled with water.  
     CONSTITUTION: High softening-point pitch is introduced into an inner vessel 3 through a feeding opening 11 to be heated and molten. The molten pitch P flows down through an outlet nozzle 7 having an opening degree controlled in the form of a small-diameter rod to pass through a pure liquid or a mixed liquid L being cooled by it. The liquid L has a specific gravity of 1.0 or less, a boiling point of 150W450°C and a surface tension of 20W60 dyne/cm (20°C). Subsequently, the pitch is cooled with water W to be granulated into small-diameter pencil-like matter. When the molten pitch flows down into the pure liquid or mixed liquid, the cooling liquid L in a surface that is in contact with the pitch is heated. As a result, a temperature difference between the pitch and the liquid L becomes small and the pitch is cooled gradually. Thus, the formation of residual stress is little, and the granulated matter having high strength can be obtained.
