Title: Detection of mask position
Inventor: AMAMIYA MITSUAKI
IPC: H01L21/027
Filed: 1984-06-18
Abstract: PURPOSE:To obtain high S/N ratio by detecting the position of a mask with characteristic X-rays radiated from an alignment mark on the mask irradiated with electron rays. CONSTITUTION:When electron rays 1 scan on a mask 2 and come to the position of an alignment mark 3, characteristic X-rays 6 specific to an element constituting the alingnment mark 3 (It is in many cases Au.) are radiated. By detecting the characteristic X-rays 6 with an X-ray detector 7, the position of the mask 2 is detected. Since the characteristic X-rays 6 have a specific wavelength for the element, high S/N ratio can be obtained. Consequently, the position of the mask can be detected in high accuracy.

Abstract: PURPOSE: To provide MOS-type semiconductor devices having a miniaturized size and a hardly breakable wiring structure by using an oxide to be converted to an insulator by selective oxidation and applying self-alignment to contacts.  
     CONSTITUTION: On a silicon substrate are formed a pair of LOCOS's 301. In the middle between the paired LOCOS's 301 an oxide film 302 with a wiring 303 on top is formed, while in the outer sides of the oxide film 302 a pair of source drains 304 are formed by ion-implantation, using the wiring 303 as mask and then treated to be exposed. All the surfaces of the thus formed components are covered with a film of silicified molybdenum 305 by sputtering, followed by forming patterns 306 of a nitride film. The resulting composite is heated in an oxidation furnace so that the sillicified molybdenum is selectively oxidized and converted to an insulator. According to this device, contacts of the source drains 304 can be formed by a single process of photolithography, dispensing with the laborous mask-setting and resulting in making very fine patterns.
