Title: Semiconductor device
Inventor: OOMURA ETSUJI
IPC: H01L21/52
Filed: 1978-03-22
Abstract: PURPOSE: To adhere a heat spreader composed of two kinds of metal to a heat sink hard enough in a region except the operating region of a semiconductor chip, without causing strain near the operating region.  
     CONSTITUTION: On electrode 8 near luminous part 10 of semiconductor chip 1, metal layer 12 is formed approximate three times as wide as luminous part 10. This layer, plated with silver, copper, etc., is large in thermal conductivity and hard to be alloyed with In solder. On the remaining part on electrode 8, gold layer 13 is selectively formed which is easy to be alloyed with In. Heat spreaders 12 and 13 are mounted on heat sink 14 and then fixed by solder 15 and, in consequence, the solder remains as soft metal In is since layer 12 is never alloyed, so that no strain will appear in the active region of the chip. As a result, layer 13 is alloyed with In and comes in hard contact with the heat sink.

Title: Method for flattening surface of semiconductor substrate with high precision
Inventor: KITAGAWA KUNIHIKO
IPC: C25F3/12
Filed: 1989-02-13
Abstract: PURPOSE:To flatten the surface of a semiconductor substrate with high precision by opposing an acicular electrode to a fine projecting part on the substrate dipped in a soln., carrying out electropolishing and selectively dissolving the fine protrusion. CONSTITUTION:The Si substrate 1 specularly finished by ordinary mechanical polishing is dipped in an electrolyte 4 contg. 5% HF in a cell 3. The acicular electrode 2 is dipped in opposition to the substrate 1, and a power source 5 capable of adjusting the voltage and current is connected to the electrode 2 and the substrate 1. Meanwhile, the matching precision of the worked surface is inspected and the fine projecting part is detected by a flatness measuring instrument (not shown in the figure) using the conventional optical or electromagnetic methods such as the optical interference method and the impedance variation method. The tip of electrode 2 is then opposed to the fine projecting part. Electropolishing is carried out under such conditions, hence the fine projecting part is completely dissolved, and the surface of the substrate 1 is flattened with high precision. Since the worked surface is kept clean by this method, the semiconductor devices can be highly integrated.

IPC: H01B7/18
Filed: 1998-02-16
Abstract: PROBLEM TO BE SOLVED: To provide a terminal processing method for a multi-core cable with excellent workability that does not apply a large load onto a core wire. SOLUTION: A plurality of elements wires 13 formed by covering a conductor 11 with an insulating layer 12 are covered by a first slip layer 15A consisting of metallic braided wires and lumped together to be also covered by a second slip layer 15B consisting of metallic braided wires. Further, an outer sheath 14 covers over outside of them to form a multi-core cable 10. To perform a terminal processing on the multi-core cable 10, one end of a core wire 13 is exposed by L1, which is a required length for the process, to connect the core wire 13 and a terminal metal fitting, and then the core wire 13 is slid by the slip layer 15A, 15B to be drawn in the outer sheath 14 so as to shorten the exposed length.  Thereby, as bending the core wire 13 is not required while assembling the terminal metal fitting to a shield connector, workability is improved and a large load onto the core wire 13 is avoided.
