Title: Apparatus for feeding electronic part chip in alignment
Inventor: KONISHI TORU
IPC: H05K13/02
Filed: 1988-09-29
Abstract: PURPOSE:To align and feed electronic part chips by receiving electronic parts through the cross section of a first path, receiving the parts through the cross section of a second path only when the width of the part is directed in the lateral direction, and providing a rotary body having a relay path that is communicated to both paths. CONSTITUTION:An aligning path 9a of a hopper 2 has a first path 13 on the upstream and has a second path 14 on the downstream. The cross section of the path 13 receives a part regardless of the direction of the width of an electronic part chip 4, and high-speed feeding is possible. The cross section of the path 14 receives the part only when the width of the chip 4 is directed in the lateral direction. A rotary body 15 is provided between both paths and provided with a relay path 16. The rotary body is rotated around the axis of the direction of the path 16. The path 16 has a size which is longer than or shorter than the length of the chip 4. The path 16 receives the chip regardless of the direction of the width as in the path 13 and has a space in which one chip can be accommodated. When a sensor 22 detects the absence of the chip, the rotary body 15 is rotated. The feeding of the chip into the path 14 and the discharge of the chip through an outlet port 12 of the aligning path 9a are continued.

Title: Semiconductor device
Inventor: HIRAYAMA HIROMITSU
IPC: H01L27/095
Filed: 1985-10-31
Abstract: PURPOSE:To improve the operation margin of a differential inverter by inputting the outputs of two cascaded inverters as a positive and a negative phase input to a differential circuit used which is used as an output circuit conventionally as to a very high speed integrated circuit device formed on a semi-insulating potassium arsenide substrate. CONSTITUTION:In the logical integrated circuit device composed of a Schottky junction type field effect transistor (FET), an output circuit is provided with the 1st inverter 2, the 2nd inverter 8 which inputs its output, and the differential inverter which inputs the outputs of the 1st and the 2nd inverters 2 and 8 in positive phase an negative phase respectively. The output differential inverter is driven in both positive and negative phase states, so the small signal voltage gain is improved by twice as large as that of a conventional circuit which uses a DC reference voltage input. For example, the source voltage (between 10 and 11) is lowered to 2-2.5V to secure a 0.5V output amplitude and when the threshold voltage of transistors 3 and 4 is set to about -0.5V so as to secure internal logical gate speed characteristics, a proper margin is obtained by this circuit constitution.

Title: Interconnection structure of semiconductor device and formation thereof
Inventor: TAGUCHI MITSURU
IPC: H01L21/768
Filed: 1995-08-30
Abstract: PROBLEM TO BE SOLVED: To obtain an underlying layer for filling a trench having high aspect ratio with an interconnection material by forming the underlying layer by sputtering under a state where the substrate is heated higher than a specified temperature but lower than the melting point of compositional material of a semiconductor device. SOLUTION: A trench 13 is made in an insulation layer 12 formed on a substrate 10 and an underlying layer 14 is formed on the insulation layer 12 including the trench 13. The trench 13 is then filled with the compositional material of an interconnection material layer 15 formed on the insulation layer 12 through reflow. When an interconnection structure is formed, the underlying layer 14 is formed by sputtering under a state where the substrate 10 is heated higher than 400 deg.C but lower than the melting point of compositional material of a semiconductor device. Since moisture absorbed into the insulation layer 12 has no adverse effect on the burying properties of interconnection material, the trench 13 can be filled surely and stably with the interconnection material. Consequently, the reliability of contact hole 16 and interconnection is enhanced while decreasing the resistance.
