IPC: H01L23/373
Filed: 1998-11-26
Abstract: PROBLEM TO BE SOLVED: To improve a semiconductor module in reliability by a method, wherein the semiconductor module is protected against damages or deformations due to thermal stress. SOLUTION: A soft metal phase 10 is dispersed into the texture of a low- melting point metal phase of a boning material (solder layer) 8 which is used for bonding the ceramic board (insulating bard) 2 of a power semiconductor module to metal (a metal thin board) 3. One or more metals selected out of Cu, Al, Ag, Au, and Sn are used as the soft metal 10, and the soft metal 10 is low in deformation resistance and excellent in thermal conductivity. Due to the presence of this dispersed phase, thermal stresses due to heat generated in a bonding process or when a current is made to flow through a semiconductor module is relaxed by a bonding material (solder layer), so that the thermal stresses imposed on the insulating board 2 can be reduced to enable it to be less deformed or cracked, and the semiconductor module can be less deformed or cracked.  Moreover, the semiconductor module is improved also in thermal conductivity, so that the thermal stresses imposed on it is more lessened, and the semiconductor module is improved in reliability.

Title: System protecting equipment
Inventor: MOTOYUKI TADAHIKO
IPC: H02P5/00
Filed: 1990-11-29
Abstract: PURPOSE:To prevent any failure or break of the whole of a system by judging the properness of the relations of conditions among a plurality of motors by a hardware provided independently of a computer based on a computer output and a signal showing the mode of the system at that time. CONSTITUTION:An output h of an anomaly detector 6 has L level if either capstan motor 7 or drum motor 8 is rotating. Another output i becomes L level only when a loading motor 9 is rotating. Therefore, the outputs h and i are at 1 level and H level before the loading motor is rotated but shift to L level when the loading motor 9 begins to rotate. Therefore, when the loading motor 9 begins to rotate, the output voltage from both the AND gate 70 and 80 becomes L level so that the rotation of capstan motor 7 and drum motor 8 is prohibited.

Filed: 1993-12-28
Abstract: PURPOSE: To provide a flash EEPROM, wherein its operation is unaffected by the occurrence of excessive erasing, while being operative at a low voltage by forming an auxiliary gate at the upper part of specified region of source/ drain, through a gate oxide film. CONSTITUTION: In a flash EEPROM having a drain surrounded with the second a low-concentration impurity region, owing to an auxiliary gate 9 which is formed at the upper part of specified region of a source 2 and a drain 3, an electron tunneling occurs between the auxiliary gate 9 and a floating gate 5 at erasing. Although excessive electrons held at a floating gate 5 are removed to generate excessive erasing, the channel under the auxiliary gate 9 maintains a non-conductive state, when no voltage above a specified level is applied to the auxiliary gate 9. Thus no operating characteristic is affected. With the auxiliary gate 9 as a gate electrode having a spacer structure, operation at low-voltage source is possible at programming time, thus realizing low-power element.

Abstract: PURPOSE:To improve recording density by providing a re-inverted magnetized region within the recording bit of a magneto-optical recording layer, and forming the intermediate value between two Kerr rotating angles corresponding to the presence and absence of the bit, respectively. CONSTITUTION:The temperature of a magneto-optical recording layer is increased to the vicinity of Curie temperature or compensating temperature by the emission of a recording laser beam. Magnetization is inverted with an external magnetic field, and data are recorded. The data are erased by emitting an erasing laser beam, applying a magnetic field whose direction is opposite to the direction in recording and inverting the magnetization of a recording bit again. At this time, multivalued recording is performed by forming the bit as the recording bit so that not only the bit wherein the magnetizing direction in the bit is uniform but also the bit wherein a re-inverted magnetized region is provided in the bit are formed. Namely, the average Kerr rotating angle of the bit is located in the vicinity of a zero angle. Thus, the recording density can be enhanced.
