Title: Target for sputtering device
Inventor: ASAMAKI TATSUO
IPC: H01L21/285
Filed: 1981-06-17
Abstract: PURPOSE:To approximate the shape of a target to an erosion distribution and to maximize the utilization efficiency of the target by making the thickness of the part corresponding to the space between the magnets of the target thicker than the thickness corresponding to the magnets. CONSTITUTION:A target 19 of a sputtering device is so formed that the 1st part corresponding to the spacing between a pair of magnets 23 and 24 is made thicker than the 2nd part corresponding to the magnets 23, 24. The thickness in the 1st part is made thinner the near the 2nd part and is approximated to the thickness of the 2nd part. This shape is approximate to the distribution shape at which the target 19 is eroded during sputtering. Therefore, if sputtering is effected by using such target 19, it is possible to increase the utilization efficiency of the target 19 up to about 80%.

At this time, water film flow 15 exists along the inside surface of the bodies 13A and threrefore the molten metal jets are pulverized by the vigorous collision and are simultaneously cooled. These are stored as a slurry in a storage tank 5A. The slurry is removed successively with a slurry pump 18, and is removed of liquid components with a centrifugal separator 19, whereby it is made into metallic powder 20. This powder is dried with an automatic dryer 21, and is made into a product 24 after classifying 22 and mixing 23.

Title: Inspecting method of logical circuit
Inventor: MATSUMOTO KEIJI
IPC: G01R31/319
Filed: 1982-05-31
Abstract: PURPOSE:To decrease test patterns in amount, by providing a dividing circuit to subtract the output of a logical circuit, and using remainder for checking the normal functioning of the logical circuit. CONSTITUTION:This method consists of the logical circuit 10 to be checked, dividing circuit 20, and a checking device 30. A remainder polynomial is used to decide on the normalcy of an output pattern from the logical circuit 10 corresponding to a polynomial, and the remainder polynomial of a polynomial foud previously by a correct logical circuit is regarded as a correct solution value; if the output of the logical circuit 10 to be cheked, i.e. the polynomial has an error, the remainder polynomial is different from the correct solution value, thereby discriminating a defective. Even when the polynomial has very long bit-length, the pattern to be checked for a normal/defective decision is the remainder polynomial, which goes never longer than the pattern of the bit length of a generating polynomial. Thus, test patterns are reduced in amount.
