Title: Manufacture of semiconductor device
Inventor: ISHIDA TETSUO
IPC: H01L21/768
Filed: 1990-02-14
Abstract: PURPOSE:To acquire a flat and smooth surface by coating a BPSG film with a polycrystalline silicon film after depositing the BPSG film and by oxidizing the polycrystalline silicon film and making the BPSG film flow by heat treatment in an oxide atmosphere. CONSTITUTION:A BPSG film 3 is deposited on a foundation step 2 produced on a semiconductor substrate 1 by CVD. Then, a polycrystalline silicon film 4 is applied to the BPSG film 3. Heat treatment is carried out in a diffusion furnace in an oxidizing atmosphere, and the BPSG film 3 is dissolved and made to flow. When heat treatment is carried out in the diffusion furnace, boron and phosphorus do not evaporate since the BPSG film 3 is coated with the polycrystalline silicon film 4, thereby preventing development of precipitation type fine particles. Thereby, a step produced on a semiconductor substrate is flattened and a flat and smooth surface without precipitation type fine particles can be acquired.

Abstract: PURPOSE:To improve the resolution of a recording picture by detecting the electrostatic charging potential of a photosensitive body by a measuring means and varying the quantity of light emission of a LED as an exposure light source according to an electrostatic charging potential state, and thus obtaining a recording surface which is nearly constant in line thickness at all times. CONSTITUTION:A surface potential measuring sensor 2 as the measuring means for the surface potential measures the electrostatic charging potential of the cylindrical photosensitive body 1. The voltage VR1 of a reference voltage setting circuit 31, the voltage VR2 of a reference voltage setting circuit 32, and the voltage VR3 of a reference voltage setting circuit 33 are supplied to respective input terminals of an operational amplifier 34 and the voltages VR1-VR3 are so set that VR1>VR2>VR3. The reference voltage setting circuit 31 is selected when the electrostatic charging potential of the photosensitive body 1 is high, the reference voltage setting circuit 33 is selected when the electrostatic charging potential of the photosensitive body 1 is low, and the reference voltage setting circuit 32 is selected when the electrostatic charging potential of the photosensitive body 1 is within a normal range. Therefore, even of the electrostatic charging state of the photosensitive body 1 changes owing to an external factor, recording is uniform in line thickness. Consequently, the resolution is prevented from deteriorating.

In the stage of the 1st pass, speed setters 1-3 and a whole stand speed setter 4 on the positive side are set at the respective stand speeds and gnawing speeds and gates 11-13 are opened. In the stage of such setting, respective reference devices of speed 8-10 and a whole stand reference device of speed 17 on the negative side are set at the respective stand speeds and gnawing speeds of the 2nd pass. The speed pattern of the setter 4 at the end of gnawing of the ST3 is increased in the 1st pass so that the gates 11, 14 are closed and opened when the material travels out through the set ST1. The outputs of the respective reference devices are changed over to D-F at the end of the 1st pass in the above-mentioned way, and in this state, the 2nd pass is started. The idle time between the passes is thus reduced drastically.

Abstract: PURPOSE:To attain reverse calculation by selecting a predicate/operator code on a display screen, inputting a predicate/operator and returning an item dis played in a cell on the screen to a variable. CONSTITUTION:A constraint processing function is attained as Prolog integrating predicate (clp-unify predicate) and a constraint logical programming(CLP) program is converted into a Prolog program. In this case, a control processing part is converted into a prescribed format and the CLP program is executed by using a Prolog processing system. Then a spread sheet cell is allowed to correspond to the CLP variable, a CLP predicate is accessed and a variable- determined result is displayed on the cell. Thus calculation/recalculation can be attained by attaining cell input, predicate/operator selection and variable formation (for returning a cell unified in an item to a variable) functions. In this case, a program for accessing a CLP predicate is formed by the combination of the cell and the predicate/operator through a pointing device such as a mouse or a keyboard.
