Title: Manufacture of semiconductor device
Inventor: UDA KEIICHIRO
IPC: H01L21/285
Filed: 1988-05-27
Abstract: PURPOSE:To eliminate a strong silicifying reaction and to substantially obviate the diffusion of dopant by forming a tungsten nitride film on the way of growing a metal tungsten film when the tungsten film is selectively grown on a semiconductor at the bottom of a contact hole. CONSTITUTION:After an oxide film 12 is formed on a p-type silicon substrate 11, a contact hole 14 is opened. Impurity ions of As or the like is doped, and heat treated to form a shallow n-type diffused layer 13. Then, the substrate is introduced into a low pressure CVD device, WF6+SiH4+H2 is employed as gas, and a thin tungsten film 15 is selectively grown only at the contact hole. Thereafter, gas sequence is switched only to N2, and a plasma is applied to form the surface of the tungsten film as a tungsten nitride film 16. This film is operated as a barrier film in case of a high temperature process. That is, it prevents the n-type impurity from diffusing out of the layer 13. The silicifying reactions of the silicon substrate and the tungsten film are disturbed by the film as a barrier and only the thin tungsten film is silicified, and hence no improper contact occurs.

IPC: G03G5/14
Filed: 1991-04-30
Abstract: PURPOSE:To obtain a sensitive body having high sensitivity and excellent repetitive characteristics in electrification and exposure by using alcohol-soluble nylon resin as the base of an underlayer and incorporating a fluorine-contg. surfactant into the underlayer.

Abstract: PURPOSE: To avoid the waste of the tape as well as to ensure an observation in detail when some change occurs by detecting the difference in the vertical correlation of the video signals and then controlling the transfer speed of the recording medium based on the difference of the vertical correlation.  
     CONSTITUTION: The video signals are supplied through input terminal 11 to be processed, and for example the video signals equivalent to one frame are drawn out with every 1000 frames to be supplied to recording head Hr. At the same time, reproduction head Hp is provided at the position distant by 180 away from head Hr to reproduce the recorded video signals. The reproduced signals are supplied to subtractor circuit 30 to obtain the difference to the input video signals. When detector circuit 31 detects that the difference is under the fixed level, the video signals are drawn out every 1000 frames; while if the difference signal is over the fixed level, switches 16 and 26 are changed over to draw out all frames. Thus the tape speed is increased.
