Title: Manufacturing method for semiconductor device
Inventor: SHINOZAKI SATOSHI
IPC: H01L21/768
Filed: 1978-07-20
Abstract: PURPOSE: To obtain a multi-layer wiring construction by utilizing a poly Si film for a first layer wiring at least while making its resistance fully small.  
     CONSTITUTION: A wiring composed of poly Si can not sustain an impurity as in an Al wiring in a low resistance if the impurity may be doped in a high density. However, if a sheet resistance may not be reduced below a predetermined value but if the wiring width be made fully great, the resistance value for the wiring can be reduced. Therefore, the poly Si film as a first layer wiring is not changed into a linear pattern as in a conventional manner, but be left as it has a maximum area. For example, when only one first layer wiring is connected to one potential, it is left over the full surface of a substrate, in order to connect a second layer wiring to the substrate, an opening is provided in a desirable connection portion of the region on the first layer wiring. A multi-layer wiring useful for a signal line for a bi-polar device or a current supplying source can be obtained.

Abstract: PROBLEM TO BE SOLVED: To make it possible to irradiate a prescribed position with dispersed X rays with a simple structure and adjustment by controlling an angle adjustment means and a transfer means according to a wavelength of dispersed X rays to be generated to maintain a prescribed course of the dispersed X rays. SOLUTION: When spectroscopic elements 1A and 1B of this X-ray spectroscope satisfy the Bragg condition and emit dispersed X rays 8 with a wavelength λ1 , incident X rays 6 and the dispersed X rays 8 are parallel to each other if incidence angles θA and θB are equal and a prescribed position P of a sample 9 is irradiated with the dispersed X rays 8. If the wavelength λ1 changes into λ2 (λ1 <λ2 ), then, a control means 5 into which such a change is inputted controls angle adjuster 2A and 2B so that the incidence angles θA and θB can satisfy the Bragg condition.  In this case, the incidence angles θA and θB are also equal and the dispersed X rays 8 whose wavelength changed into λ2 are parallel to the incident X rays 6, but the height of its course changes and the X rays 8 irradiate off the position P of the sample 9. Therefore, the control means 5 also controls a transfer means 4A and moves the spectroscopic element 1A together with the angle adjuster 2A in the y direction and the dispersed X rays 8 maintains a prescribed course and irradiates the position P.
