Title: Formation method of copper wiring film
Inventor: SHINOHARA KEIJI
IPC: H01L23/52
Filed: 1990-06-12
Abstract: PURPOSE:To prevent the oxidation which starts from the surface of a thin copper film by forming said thin copper film on a titanium oxinitride film, which serves as a barrier metal by way of an oxidation prevention film made of a conductive material which dose not contain oxygen. CONSTITUTION:An oxidation film 9 is formed on a thin copper film 8 where a semiconductor wafer 1 is not exposed to the atmosphere after the film 8 is formed. When the film 8 is formed based on sputtering or CVD, a titanium oxinitride film 9 is formed without taking out the semiconductor wafer 1 from the sputtering device or the CVD device into the atmosphere. This film can be formed by sputtering with TiN as a target or by active sputtering based on N2 of Ti. The semiconductor wafer is picked up from the device after the film 9 is formed. When the film 9 is formed in this manner, the film 9 protects the surface of the film 8, which prevents the formation of an oxide film.

Filed: 1996-05-27
Abstract: PROBLEM TO BE SOLVED: To output an origin signal with high precision by using a circular lattice for an origin phase slit, even in the case of a resolution of a small slit pitch. SOLUTION: The emitted light of each light source 3 is transmitted through a displacement detecting phase first slit 11 on a movable scale 1 and an origin phase first circular slit 12. Each transmitted light is transmitted through a displacement detecting phase second slit 21 on a fixed scale 2 and an origin phase second sircular slit 22, and the change of the quantity of light of the displacement phase light with the origin phase light transmitted is detected by each photo detector 4 individually, and the quantity of displacement and the position of the origin are detected. On this occasion, the change of the quantity of light changes by Moir* fringe effect of the circular slit fringes.  In addition, the origin phase signal is put within one period of the displacement detecting phase, and a high precision is obtained, by making the pitch of the slits 12 equal to that of the slits 11 or less. Besides, a sufficient quantity of light can be obtained even in the case of a resolution of a small slit pitch, since the quantity of light transmitted is determined by the area occupied by the slits 22.
