IPC: H01L21/67
Filed: 1990-03-05
Abstract: PURPOSE:To facilitate the movement of a blade for cutting to the next cutting line intact without the movement of the Z-axis of the blade and to contrive to shorten a cutting time by a method wherein a tape of a structure, wherein the thickness of a part, which is adhered on the rear of a wafer, of the tape is different from that of the tape part in the vicinity of the above part, is used. CONSTITUTION:A tape is an adhesive tape 3a with an adhesive layer 2, which is 10mum or thicker in thickness and is provided under the rear of a semiconductor wafer 5 to be joined to a base film 1, under the part of the rear of a frame 4 for tape fixing use or on a part excluding doughtnut-shaped regions between the ends of the wafer 5 and the frame 4. After this tape is adhered to the rear part of the frame 4, the rear of the wafer 5 is adhered on the central part, on which the layer 2 is located, of the tape, the tape is held by suction on a cutting device stage, the height of a blade 6 for cutting use is set in such a way that the amount of notch of the tape is cut in 5mum or thereabout in a reciprocating cut by the blade 6 and a complete cutting of the tape is performed. When the blade 6 is moved to the next cutting line, there is not the layer 2 between the outer peripheral part of the wafer and fixing rings. Thereby, the blade can be moved to the next cutting line without the movement of the Z-axis of the blade 6.

Title: Semiconductor device
Inventor: SATO NORIAKI
IPC: H01L27/10
Filed: 1987-03-11
Abstract: PURPOSE:To highly integrate a semiconductor device and to prevent a leakage current between elements formed on a substrate from generating by forming a groove-shaped isolation region deeper than that of a groove-shaped MOS capacitor. CONSTITUTION:A silicon oxide film 31, a silicon nitride film 32, an SiO2 film 33 are formed on a P-type Si substrate 10. The film 33 is dry etched by patterning and resist. After the resist is removed, with the film 33 as a mask a groove of 3-5mum of depth is formed in the substrate 10. Further, an insulator for forming a groove-shaped isolation region 11, i.e., an SiO2 film 35 is formed. Groove-shaped MOS capacitors C1, C4 are separated by the region 11. Thus, even when it is highly integrated, depletion layers 21, 22 can maintain the state separated by the region 11 formed deeply. Accordingly, since a leakage current does not flow, information of a cell is not broken.

Abstract: PURPOSE:To obtain the antenna performance in the optimum condition independently of the condition of the antenna installation place by arranging a member, which has high specific permeability and specific conductance behind a plane antenna with an air layer between them. CONSTITUTION:An air layer 14 of a prescribed length gap or an urethane foam material 15 is packed as a nonmagnetic space behind a plane antenna 9 where a spiral coil 10 is formed in the front or a case 8, and a prate 12 like an aluminium plate or a copper plate which has a specific permeability approximating one and a high specific conductance is arranged behind it, thus constituting an antenna equipment.

Abstract: PURPOSE:To prevent a difference in the XY coordinate values of the center point of a mark between values read by a scanner camera and those read by an index, by making the XY coordinate axis reference of the scanner camera coincident with that of the index. CONSTITUTION:A controller is switched to a manual read side and a manual switch is operated to move a head.

Abstract: PURPOSE:To enable high integration and high performance of a semiconductor element, by using a SixNyOz film as a mask in order to perform selective oxida tion of a part in a surface region of a semiconductor substrate. CONSTITUTION:A SiO2 film 2 is formed thinly (0Angstrom  to 500Angstrom ) on a semiconductor substrate 1, and a SixNyOz film 3 is formed thickly (1000Angstrom  to 5000Angstrom ) thereon.

Since the SixNyOz film has almost no stress, the under SiO2 film can be made thin and the SixNyOz film itself can be made thick. Hence, the oxygen is prevented from penetrating laterally during selective oxidation end almost no bird's beaks are made to grow.
