Abstract: PURPOSE:To prevent Cu from oxidizing when an interlayer insulating film is filmed by CVD process while making a wiring with excellent anti- electromigration at low resistance by means of encircling Cu by a barrier metal layer. CONSTITUTION:An insulating film 2 such as PSG etc. is provided on the surface of an Si substrate 1 to grow a barrier metal layer 3 such as TiW etc. on the surface of insulating film 2. First, Cu is grown on the surface of barrier metal layer 3 to be patterned and formed into a Cu layer 4 and then a barrier metal 5 such as Tin or W or TiW is formed on the surface of layers 3 and 4. Second, a resist film 6 is placed on the surface of layer 5 on the surface of layer 4 while the layers 3, 5 are unisotropically dryetched to be removed excluding the part opposing to the film 6. Third, an interlayer insulating film 7 such as PSG etc. is grown on the surface of layer 4 encircled by the layers 3, 5 as well as the insulating film 2. In such a constitution, the Cu layer 4 encircled by the layers 3, 5 is not oxidized when the interlayer insulating film 7 is formed so that contact resistance may be lowered.

Title: Pinch valve
Inventor: MURAI YONEO
IPC: F16K7/07
Filed: 1983-11-18
Abstract: PURPOSE:To improve mechanical durability of a pinch valve by forming a pair of opposite thin wall portions at the central part if a flexible tube to alternately produce Z-shaped and S-chaped bending seal through initial pressure contact with difference in positin of the thin wall portions on every pressure receiving. CONSTITUTION:A cylindrical body l has a take-in port 2 for pressurized air, and a concentric cylindrical flexible tube 3 is mounted in the interior of the body. Bothe ends of the tube 3 are blocked up airtightly at flange portions, and a pair of thin wall portions 3a, 3a vertically confronting each other are formed in the vicinity of the central poriton of the tube. When pressurized air is pressed into the take-in port 2 of a pinch valve, buckling is caused at thin wall portions having relatively lower strength than the other thick wall portions 3b so that the thin wall portions are pressed to each other. When the thin wall portions are further pressureized, the thin wall portions cause a difference in position to block up the tube all over the surface with the Z-shaped bending seal. After the pressurized air is discharged, on pressing the pressurized air into the take- in port. S-shaped bending seal is caused by redidual stress.
