Inventor: SUZUKI HISAYA
IPC: H01L21/28
Filed: 1991-09-04
Abstract: PURPOSE:To decrease the aspect ratio by selectively separating a high melting point metal in a contact hole only by a method wherein, before performing the pressure-reduced CVD process, a substrate surface is plasma-processed in the reducing gas atmosphere to be activated. CONSTITUTION:A specimen comprising an Si substrate whereon an SiO2 film 2 having a contact hole 3 made therein is formed is contained in a plasma device to be plasma-processed so that the substrate surface including the contact hole 3 may be activated. Through these procedures, an Si-passivated film (SiO2) can be removed. Next, the pressure-reduced CVD process is performed using WF6H2 so that tungsten 5 may be selectively deposited on the bottom part 4 of contact hole 3 to decrease the aspect ratio. On the other hand the SiO2 surface whereon Si atoms and O atoms are ion-coupled will not be affected by the plasma surface-processing step to be stabilized. Accordingly, the tungsten atoms, even if collides with one another during the pressure-reduced CVD process, can be desorbed without depositing on the SiO2 surface.

Abstract: PURPOSE:To improve film forming efficiency and to enable high-speed film formation by successively applying high-frequency voltages varying in amplitude and repeating the voltage application in the CVD method for converting plural film forming gases to plasma by the application of the high-frequency voltages. CONSTITUTION:The plural gases are introduced as the film forming gases into a vacuum vessel and the high-frequency voltages having the amplitude of the varying magnitude meeting the conversion of the respective gases to plasma are successively applied thereto. This operation is repeated. The gases which as liable to be cracked by the low voltage are mainly cracked at the time of applying the voltage of the small amplitude. The gases which are hardly cracked by the low voltage are cracked as well or the gases which are easily cracked by the high voltage are mainly cracked at the time of applying the voltage of the large amplitude. Consequently, the films are efficiently formed by regulating the amplitude of the respective high-frequency voltages to be repetitively applied and the time distribution thereof according to the kinds of the gaseous raw materials and the desires film compsns. The films are formed at a high speed without changing the film compsns. by a voltage increase.

Filed: 1989-08-30
Abstract: PURPOSE:To prevent generation of tension breakage by constituting a turn back part of grooves with a different tilt from each other, in the turn back part of an end part of the traverse groove. CONSTITUTION:A tilt angle theta1 of grooves 11, 12 in an intermediate part, angle theta2 of traverse grooves 13, 15 and an angle theta3 of traverse grooves 14, 16 are set so that a relation where theta2<theta1<theta3 is established. Now when a drum 10 is rotated in the direction of an arrow head 17, a thread is fed leftward by arrow heads A1 to A4 along the groove, inversely fed rightward in the direction of arrow heads B1 to B4 and traversed. For instance, in a thread, guided in the groove 13 in the direction of the arrow head B4, a traverse speed V4, when the thread is moved in the right direction, is decreased relatively smaller than a traverse speed V23, when the thread is moved in the groove 11 in the direction of the arrow head B3, and the thread is moved at a speed slower than the existing speed from a crossing part P1 to reach a turn back end part T1 and quickly moved by the groove 14 after inversion. Accordingly, because of no rapid change between the groove 13 and the shallow groove 14 in the inversion part with no necessity for making the groove 13 deep. fluctuation of tension is suppressed small with end breakage avoided.

Abstract: PURPOSE:To make it possible to surely feed a robot main body by performing the carrier control of a power source cord, interlocking with the autonomous running of the robot main body and always carrying the only necessary amount of power source cord wherever the robot main body moves. CONSTITUTION:While a robot 11 is running straight, the advancing direction of a robot main body 12 is always monitored so that the output of a pair of ultrasonic sensors 26 opposed to the wall surface of a room may continue to show about 2cm, for instance, respectively. When they shift from the wall surface, the correction of the direction is performed by changing the direction of a front wheel 13. A capstan motor 46 rotates a capstan roller at prescribed speed so that a power source cord 30 may be fed at the same speed as the running speed of the robot main body 12 while the robot main body 12 is running straight. Therefore in the wall side running from a start point A, the power source cord 30 is fed by only necessary length, interlocking with the running of the robot main body 12. Then, the fed length is measured by a potentiometer 35 and an encoder 36.
