Title: Manufacture of semiconductor device
Inventor: SUGIMOTO NAOAKI
IPC: H01L21/3205
Filed: 1987-12-10
Abstract: PURPOSE:To obtain an alignment pattern to be accurately superposed and to improve the throwing power of the wiring layer at the contact by simultaneously forming the alignment pattern and burying a contact hole. CONSTITUTION:An insulating film 12 is formed on a substrate 1, coated with a resist film 13, and omitted patterns are formed on the contact hole and the alignment pattern. With the resist pattern as a mask the film 12 is anisotropically etched in depth D, a metal film 14 having a thickness D covers it by depositing or sputtering, etc., and the film 13 is then removed by dissolving. Thus, since a variation in the thickness of the resist film does not occur near the alignment pattern even if the resist is spin coated, a variation in the intensity of a reflection signal due to an interference effect is eliminated, and the alignment pattern can be accurately superposed. When the coated metal film is also buried in the contact hole and a wiring layer 34 is formed, the peripheral adherence of the layer 34 in the contact hole is improved.

Abstract: PURPOSE:To make a car wash brush lightweight, convenient for use and highly efficient, and enable the use of the brush as a sprinkler as well, by providing a body monolithically molded with a transparent or semitransparent material, a jet nozzle directed from a water hose connection part to the body, and an outside air introduction hole. CONSTITUTION:A solid detergent 15 and a small rotary ball 16 are preliminarily set in a body 1 via the introduction hole 5 thereof. Water introduced through the nozzle 14 of a cap 2 forcibly entraps the outside air via an air introduction hole 13 formed on the rear edge of the cap 2, and enters the body 1 while generating a sound with the entrapped air. Furthermore, the water is blown toward a space 11 via a jet hole 7 while whirling. In this case, the state of air introduction can be externally watched by forming the cap 2 with a transparent material. Also, the introduced water (w) from the nozzle 14 to the body 1 does not completely occupy the space of the body 1 because of the existence of the air introduction hole 13, and is smoothly jetted from the jet hole 7 on the bottom of the body 1. Consequently, a water amount within the body 1 can be made small even during the use of the brush, and the weight of the body 1 during service can be correspondingly reduced, thereby ensuring conveniences for a washing work.
