Patent number: 6032611Abstract: In order to form a single-crystalline thin film on a polycrystalline substrate using plasma CVD, a downwardly directed mainly neutral Ne atom current is formed by an ECR ion generator (2). A reaction gas such as silane gas which is supplied from a reaction gas inlet pipe (13) is sprayed onto an SiO.sub.2 substrate (11) by an action of the Ne atom current, so that an amorphous Si thin film is grown on the substrate (11) by a plasma CVD reaction. At the same time, a part of the Ne atom current having high directivity is directly incident upon the substrate (11), while another part thereof is incident upon the substrate (11) after its course is bent by a reflector (12). The reflector (12) is so set that all directions of the parts of the Ne atom current which are incident upon the substrate (11) are perpendicular to densest planes of single-crystalline Si.Type: GrantFiled: March 19, 1997Date of Patent: March 7, 2000Assignees: Neuralsystems Corporation, Mega Chips CorporationInventors: Toshifumi Asakawa, Masahiro Shindo, Toshikazu Yoshimizu, Sumiyoshi Ueyama

Patent number: 5565767Abstract: A plurality of bare semiconductor IC chips are mounted on a base substrate. The base substrate and IC chips are sealed in a package to constitute a multichip module. Diodes are disposed on the base substrate so that an end of each diode is connected to a terminal for connecting each IC chip with said base substrate and the other end thereof is connected to a prescribed voltage. As a result, it is possible to inspect the base substrate by contacting probes only with a connecting pad between the base substrate and a package, to reduce the number of pins of a probe card, to produce a cheap probe card and to reduce a rate of imperfect contact between the probe card and an inspecting pad.Type: GrantFiled: February 5, 1993Date of Patent: October 15, 1996Assignee: Mega Chips CorporationInventors: Toshikazu Yoshimizu, Hideo Azumai

Patent number: 5451814Abstract: A multi-chip module semiconductor device including a plurality of IC chips arranged in a side-by-side relationship on a supporting member such as a tab is provided. Each of the IC chips is provided with an array of bonding pads for connection with the exterior of the device only along such side to which no other IC chip is disposed adjacent thereto.Type: GrantFiled: March 1, 1993Date of Patent: September 19, 1995Assignee: Mega Chips CorporationInventor: Toshikazu Yoshimizu

Patent number: 5136306Abstract: A thermal transfer printing apparatus that comprises a thermal head, an ink transfer medium having an ink layer, a printing medium to which the ink is to be transferred, a platen for pressing the ink transfer medium together with the printing medium against the thermal head. The thermal head comprises a substrate, a plurality of heating elements disposed on a surface of the substrate close to an end of the substrate and two electrode lines connected to each of the plurality of heating elements and formed on the substrate. Each line extends from each heating element toward a direction opposite to the substrate end with respect to the heating elements. The apparatus further comprises a pulling out unit for separating and pulling out the ink transer medium from the printing medium after passing over a position of the heating elements and a direction change mechanism for changing direction of the ink transfer medium pulled out by the pulling out unit with respect to the surface of the substrate.Type: GrantFiled: July 12, 1990Date of Patent: August 4, 1992Assignee: Ricoh Company, Ltd.Inventors: Toshikazu Yoshimizu, Kenji Fujita, Takashi Seigenji

Patent number: 5048179Abstract: An IC mounting method and its resulting structure, such as an IC card is provided. An IC card includes a metal plate formed with at least one hole, and an IC chip is located fixed in position in the hole with a filler material filling the gap between the hole and the IC chip. An interconnect pattern is provided on the plate with an electrically insulating film sandwiched therebetween, and the interconnect pattern is in electrical contact with a contact pad of the IC chip. Preferably, the surface of the IC chip on which the contact pad is provided is substantially flush with one surface of the plate. When an electrically insulating film is fixedly attached to a substrate having a hole, in which an IC chip is fixedly provided, by an adhesive agent, the material of the film is selected to be similar to the material of the adhesive agent.Type: GrantFiled: February 14, 1990Date of Patent: September 17, 1991Assignee: Ricoh Company, Ltd.Inventors: Masahiro Shindo, Toshikazu Yoshimizu, Kenichi Kurihara, Shunpei Tamaki, Toshio Kawakami, Yukio Kadowaki, Shoji Matsumoto
