Filed: 1985-08-26
Abstract: PURPOSE:To prevent an Si3N4 film from cracking by forming a CVD film, heat-treating before forming the Si3N4 film, and thermally shrinking the CVD film. CONSTITUTION:A CVD SiO2 film 9 is formed on an Si substrate in which elements have been formed, heat treated at 800 deg.C for 10-20min to thermally shrink the film 9. Then, an Si3N4 film 10 is coated by a reduced pressure CVD method, and an AsSG film 11 is superposed as H blocking film and reflowing film at low temperature. Since the film 9 has been already annealed even if heated in case of reflowing, no crack occurs in the film 10. Accordingly, H2 invasion blocking force is enhanced. Then, even if a plasma Si3N4 film 12 which contains the H is coated, the element in the lower portion is stably operated.

Filed: 1985-08-28
Abstract: PURPOSE:To enable effectively controlling the capacity of a compressor by giving to the compresso a command as to a totalized value of a compressor commanded rotational speeds based on a set room temperature commanded from respective indoor units and a current room temperature. CONSTITUTION:The rotational speeds N1, N2 and N3 are commanded from respective units 1, 2 and 3 as required rotational speed signals based on the difference between the set temperature of a temperature adjustor and an actual room temperature. When a required rotational speed signal N1 of the indoor unit 1 and a required rotational speed signal N3 of the indoor unit 3 are supplied to a control part 4, said part 4 judges that two units are in operation and calculates the total sum of the required rotational signals N1 and N3 thereby to determine the compressor rotational speed command. By this determined compressore rotational speed command, an inverter 5 is controlled to operate the compressor 6. However, the control due to the total rotational speed is set such that the compressor 6 stops in a maximum rotational speed range, whereby a wasteless capacity control of the compressor is possible and further evils accompanied by the overload operation or the over capacity operation can be removed.

Title: Method for forming hardened bump for semiconductor device and device prepared by the same
Inventor: STUART E GURIAA
IPC: H01L21/321
Filed: 1997-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a method for forming a hardened bump, which has high resistance against physical shock, for a semiconductor device and a device prepared by that method. SOLUTION: A semiconductor device 35 is provided with a bump 33 containing a 1st tin layer 40, bulk bump layer 46 and 2nd tin layer 44. The bulk bump layer 46 is formed by sticking lead together with tin or the other hardening material. When the bump is deformed by physical force before sticking to the next level substrate, the extendability of the bump is deteriorated so as to sufficiently prevent the deformation caused by a probe or treatment, for example, by introducing tin into the bulk. However, the bump maintains flexibility sufficient for being immune to stress after sticking to the next level substrate as well. As a suitable style, tin is added to the bulk bump layer in 2-10 atomic % of the bulk bump layer.

Abstract: PURPOSE:To make two-layered spiral heat exchanger with a simple structure by a method wherein multitude of element plates of only one kind are manufactured to laminate them changing their angles by 180 deg. and integrate them by means of diffusion welding or the like. CONSTITUTION:When an element plate, turned by 180 deg. about a rotary symmetric axis 7, is disposed on a basic element plate, a symmetrical point 5 comes on a hole 2 and a symmetrical point 4 comes on a hole 3 while the straight line part of an U-shaped groove coincides with each other. Now, the number of plates is supposed to be four sheets A-D. Respective holes 2-5 of each plate are explained by notations 2A, 3A,...2B, 3B,... or the like by suffixing A-D. Liquid, entered from a position 8 passes through the hole 3A from the hole 5A downwardly, through the hole 2B from the hole 4B downwardly and arrives at the hole 9 through the holes 5C, 4D, 2D sequentially. In the same manner, the liquid entered from the position 10 flows to the position 9 through the holes 3D 5D  2C 4C 3B 5B 2A 4A sequentially. Thus, the spiral flow path of counterclockwise from the upper part to the lower part and the clockwise spiral flow path from the lower part to the upper part are formed, therefore, the two- layered spiral counterflow heat exchanger may be obtained.

Title: Manufacture of semiconductor device
Inventor: MORI KIYOSHI
IPC: H01L27/088
Filed: 1999-07-01
Abstract: PROBLEM TO BE SOLVED: To obtain performance required in each of a MOS transistor in a semiconductor memory and a MOS transistor in a logic device even if a system LSI wherein the semiconductor memory and the logic device are combined together is manufactured. SOLUTION: Formation of silicide 7 on a logic device region 11 allows low resistance to be implemented in a conductive film 4, such as polysilicon which will become an electrode of a MOS transistor, and a diffusion layer 9. Hence, according to this method, a semiconductor device can be manufactured, wherein not only a MOS transistor usable for a logic device of which high-speed operation is required, but also a MOS transistor usable for a DRAM of the like of which microfabrication is required. Further, since the structure of each MOS transistor is not modified, the semiconductor device can be manufactured, wherein the MOS transistors are equivalent in their performance.
Patent JP-S6080277-A (JP)
Title: Thyristor
Inventor: SAITOU TADAYOSHI
IPC: H01L29/74
Filed: 1983-10-07
Abstract: PURPOSE:To facilitate the control of the gate trigger current by a method wherein, in an SCR of PENBNE structure, the NE layer is elongated immediately under the gate electrode of the NB layer so as to become thinner than the PE layer and not to come in contact with the surface of the gate electrode. CONSTITUTION:The NE emitter elongated layer 8 keeps a distance B between the bottom of a PB base layer 3, and the thickness B of the layer 3 is made larger than the distance A between and NB base layer 4. At the time of ignition, part (a) of the gate current flows through the surface of the layer 8 and is not directly contributed to ignition. Further, the electron injection from the layer 8 due to part (b) of the gate current flowing immediately under this layer is not directly contributed to ignition because the lateral resistance of the layer 3 immediately under the layer 8 is smaller than that immediately under the layer 4. Therefore, the breakdown in the elongated layer due to a high di/dt does not generate, and the strength against the surge current does not decrease. This construction enables the high sensitivity SCR to be obtained at a low cost by facilitating the control of the gate trigger current by adjustment of the reactive component.
