Title: Semiconductor device
Inventor: KUROSHIMA YUTAKA
IPC: H01L21/60
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor device, in which junction strength on a mounting substrate can be enhanced, underflow materials can be dispensed with, highly accurate and strong ribs can be obtained relatively easily, and the creeping of hot air to a solder bump side cannot be interrupted at the time of reflow. SOLUTION: Plural ribs 15 are arranged at the outer peripheral parts of an interposer 11 and interval parts between the columns of solder bumps 14. As a result, the joint strength of a ball grid array (BGA) 10 after mounting can be increased. Thus, it is not necessary to provide an underfill member. Each rib 15 is integrate with the interposer 11. Therefore, highly accurate and strong ribs 15 can be obtained relatively easily. The ribs 15 are in parallel to each other. As a result, the creeping of heat at the reflow to the bump 14 side cannot be interrupted. Thus, the generation of junction nonconformities due to the non-transfer of the hot air to each solder bum 14 on the other face of the interposer 11 can be eliminated.

Title: Projective television receiver
Inventor: OYA TOMOYUKI
IPC: H01J31/10
Filed: 1992-04-07
Abstract: PURPOSE:To provide a sufficient radiating function at low cost by connecting a radiating fin to a vessel filling liquid in a space around the receiver. CONSTITUTION:A fluid vessel 4 connecting a cathode ray tube 1 and a projective lens 2 is filled with transparent liquid 3, and a radiating fin 5 is connected to one part of the liquid vessel 4 by a vis or the like. Since this fin 5 can be optimumly designed concerning the size and the form without limiting the vessel form for obtaining a required radiating amount, the required radiating amount can be sufficiently obtained. ON the other hand, the temperature of three receiver parts having various input power is adjusted corresponding to the difference of the radiating amount by connecting/disconnecting the radiating fin 5 and changing the size of the fin 5, and a focal plane is reduced. Further, heat conductive sheets 6 and 6' are interposed between the vessel 4 and the radiating fin 5, and the radiating amount is controlled by adjusting the quantity of heat transmitted from the vessel 4 to the radiating fin 5 corresponding to the difference of heat conductivity caused by the material.

Title: Manufacture of semiconductor laser
Inventor: OKANO ESEKO
IPC: H01S5/12
Filed: 1988-04-06
Abstract: PURPOSE:To facilitate maintenance of the shape of a diffraction lattice without thermal deterioration by a method wherein the diffraction lattice is formed by interference exposure and filled with a guide layer. CONSTITUTION:After a layer 2 which has a band gap not larger than the band gap of a guide layer 4 formed on it and smaller than the band gap of InP is built up on an InP substrate 1, trenches which reach the inside of the InP substrate from the layer 2 are formed to provide a diffraction lattice and, successively, the trenches are filled with an InGaAsP guide layer 4. As a result, liquid growth is carried out while the diffraction lattice surface is protected by quaternary layers 5, 6 and 7. Therefore, the extinction of the diffraction lattice caused by maintaining a high temperature during liquid epitaxy is avoided, so that an excellent distributed feedback type semiconductor laser can be manufactured by maintaining the neatly arranged diffraction lattice. Thus, even if the diffraction lattice is kept in the high temperature of liquid epitaxy, its shape is not extinguished by thermal deterioration.

Title: Manufacture of semiconductor device and semiconductor device obtainable thereby
Inventor: OWADA NOBUO
IPC: H01L21/336
Filed: 1989-04-05
Abstract: PURPOSE:To prevent a deposit becoming a deposition nucleus of a W film from remaining on the sidewall of a connecting hole by a method wherein, during the process of filling up the connecting hole formed in insulating films with the W film, when the connecting hole is formed, a positive oblique angle is made on the sidewall of the connecting hole. CONSTITUTION:A connecting hole 12 reaching n<+> type semiconductor regions 9 is formed by dryetching respective parts of interlayer insulating films 11, insulating films 10 and gate insulating films 3 using a photoresist as a mask. At this time, the said respective parts are dryetched so that the sidewall of the hole 12 may make a positive oblique angle theta with a substrate 1. Next, the surface of the substrate 1 is sputter-etched by Ar ion produced in plasma. At this time, since the positive oblique angle theta is made on the sidewall of the hole 12, any reaction product deposited on this sidewall can be removed rapidly by a given shock of Ar ion. Later, the inside of the hole 12 is filled up with a W film 13. Through these procedures, the reliability of the connecting hole 12 upon the connection can be enhanced.

Abstract: PROBLEM TO BE SOLVED: To make it easier to recognize a tire in the dark or at night by applying a light reflecting material to tire grooves material so that the tire glows by a light source such as headlamps of an approaching vehicle. SOLUTION: To the bottom of a groove 2 of the surface of a tire 1, a material 3 is applied or adhered, which reflects light and is used for various signs on the road or signboards for controlling the traffic.

The light reflecting material 3 can be contained in a tire, adhered to a tire, or it can be a light accumulating coating. In this way, the tire can be recognized and identified easily, so that accidents including rear-end collisions are reduced.

Title: Optical lens for optical scanning and its manufacture
Inventor: ISHIKAWA HIROMI
IPC: G02B3/00
Filed: 1991-04-18
Abstract: PURPOSE:To use a lens material without any waste and to reduce the manufacture cost by cutting the lens material, which is formed rotationally symmetrically about an optical axis, into >=2 striped parts, which do not include the optical axis, across the optical axis. CONSTITUTION:Two striped convex lenses 4 can be formed symmetrically across the optical axis 3 of a circular convex lens material 2 which is cut into the two striped convex lenses 4. Similarly, a circular concave lens material 6 can be cut into two striped concave lenses 8 without including the optical axis. Further, desired striped lenses can be cut symmetrically from outside those lenses 4 and 8. Thus, the lenses are cut without including the optical axis to form >=2 lenses by using one lens material, and the optical axis may be included as long as >=2 lenses can be cut. The striped lenses 4 and 8 have excellent optical characteristics when cut as close to the optical axes 3 and 5 as possible.
