Title: Semiconductor element
Inventor: ONO SHIGENORI
IPC: H01L21/52
Filed: 1986-11-14
Abstract: PURPOSE:To reduce the fatigue of solder, by soldering stress buffer metal to the rear surface of a semiconductor chip, and soldering an electrode having stress buffering characteristic to the surface of the semiconductor chip. CONSTITUTION:An electrode 6 has a linear expansion coefficient close to that of a semiconductor chip 1 and consists of a material such as Ni-Fe alloy having excellent machinability. The electrode 6 is soldered to the surface of the semiconductor chip 1. The electrode 6 has a stress buffering characteristic. As a stress buffering metal 4, molybdenum, Ni-Fe alloy and the like are used. When a current supply to a semiconductor element is repeated, the current intermittently flows through the electrode 6, the semiconductor 1 and the stress buffering metal 4. The temperature of the semiconductor element is repeatedly increased and decreased. Each part is repeatedly expanded and contracted. Accordingly, solder connecting the parts is fatigued. Since the linear expansion coefficients of the semiconductor chip 1, the stress buffering metal 4 and the electrode have the close values, the semiconductor element is intermittently energized. Even if the temperature is increased and decreased, the degree of the solder fatigue becomes less than a conventional element.

IPC: G09G3/20
Filed: 1989-10-18
Abstract: PURPOSE:To display an input picture accurately by correcting a picture data outputted to each fiber block in the vertical direction based on the arrangement state of a fiber block measured in advance and correcting an output picture in response to the arrangement state of the fiber block. CONSTITUTION:A picture data inputted respectively to delay memories 22a - 2f provided to plural stages is delayed by the time of one line of picture scanning and outputted.

Title: Formation of contact hole
Inventor: TOUNOHARA TOMOYOSHI
IPC: H01L21/3065
Filed: 1997-10-06
Abstract: PROBLEM TO BE SOLVED: To facilitate removal of insulation film in a contact hole by laminating an inorganic insulation film on an insulation film at a specified etching selective ratio and then etching the inorganic insulation film. SOLUTION: An inter-layer insulation film (SiO2 ) 11 is formed on an Si substrate 10, and an inorganic insulation film (SiON) 12 is laminated. A resist 13 of organic material, having a pattern 14 corresponding to a contact hole 15, is then printed thereon and used as a mask for opening a contact hole by etching. Selective ratio of etching is adjusted to a specified value between the SiON film and the SiO2 film. When residual film 16 at SiO2 is left at the bottom in the opening of a contact hole 15' due to insufficient etching, only the residual film 16 of SiO2 is removed by extra etching using the SiON film 12 as a mask, thus making a contact hole 17 having a normal opening.
