Title: Chip carrier
Inventor: YAMAGUCHI YUKIO
IPC: H01L23/04
Filed: 1983-10-03
Abstract: PURPOSE:To improve the characteristics of heat dissipation remarkably, and to mount parts with high density by dissipating heat generated from an LSI chip through a heat dissipating body fitted to a chip carrier. CONSTITUTION:A space in which a heat dissipating body 12 is loaded is formed to an upper section and a space in which an LSI chip 13 is loaded to a lower section respectively in a carrier proper 1, and a conductor circuit 16 through which artibrary positions on both surfaces are connected is fitted to a terminal board 15. Leads 17 for the LSI chip 13 are connected electrically to the conductor circuit 16 through thermocompression bonding. soldering, etc. while the LSI chip 13 is connected to the heat dissipating body 12 by a cementing material 14 consisting of solder or adhesives. The carrier proper is sealed with a sealing material 18, such as a resin, low melting-point glass, etc. for protection. Accordingly, since a chip carrier transmits heat over a conductor having thermal resistance lower than that of the quality of material of the carrier proper 11 such as alumina ceramics-for example, a copper-tungsten composite metal-and heat is transmitted over a heat sink, etc. mounted onto the chip carrier, the heat dissipation properties of heat are improved, and the LSI chip having a large calorific value can also be loaded.

IPC: H03F1/00
Filed: 1989-07-19
Abstract: PURPOSE:To decrease the effect of a temperature change on the output power by limiting the bias control with an output adjustment circuit only to a final stage amplifier via a 1st switching circuit. CONSTITUTION:When the supply of a switching pulse SWS is started to switching circuits 5, 6 a bias voltage Vcc2 in response to a power voltage Vcc1 adjusted by an output power adjustment variable resistor 4 is generated from the circuit 5 and the bias voltage Vcc2 is fed to a bias circuit of the final stage amplifier 3. Thus, an input signal is amplified in response to the bias voltage Vcc2 set by the variable resistor 4 in the final stage amplifier 3. On the other hand, a prescribed bias voltage Vcc3 in response to the power to voltage Vcc is generated from the circuit 6 and fed respectively to the bias circuit of the amplifiers 1, 2 of the 1st stage and 2nd stage. Thus, an input signal Vin is amplified in response to a prescribed bias by the amplifiers 1, 2 of the 1st stage and 2nd stage. Then the base potential is kept to a prescribed value or over to suppress the deterioration in the transmitter characteristic.

Title: Thin-film semiconductor device
Inventor: UEDA TORU
IPC: H01L21/336
Filed: 1985-08-23
Abstract: PURPOSE:To inhibit a lateral diffusion on the activation of an impurity implanted to a semiconductor substrate,and to form a thin-film transistor having short gate length by designing the thickness of a semiconductor film in an extent that the standard deviation of the range of implanting ions is added to the flight range of the ions. CONSTITUTION:A polycrystalline silicon film 11 is formed onto insulating substrate 10 through a thin-film manufacture technique such as CVD. The polycrystalline silicon film 11 is formed so that film thickness thereof is brought to an extent that the standard deviation DELTARP of the range RP of implanting ions is added to the range of the ions. The range RP changes by the kinds of impurities and implantation energy, and is determined so as to be positioned at approximately the center of the thickness of the polycrystalline silicon film. Accordingly, a space in which the impurity can be diffused in the depth direction is shortened, thus cutting down the heat treatment time for implanting ions, then inhibiting the lateral diffusion of the impurity.

Filed: 1997-07-11
Abstract: PROBLEM TO BE SOLVED: To provide a method of manufacturing a semiconductor substrate, wherein homogeneity of a porous silicon layer is improved, while manufacturing cost of a semiconductor element is lowered. SOLUTION: The manufacturing method is related to a semiconductor substrate for forming a large-area thin-film single-crystal silicon semiconductor element. Here, an adhesive layer comprises a polysilicon layer 12, and the surface of the polysilicon layer 12 is polished for bonding. To release a thin-film single-crystal silicon layer 13 from a single-crystal silicon substrate 14, a porous silicon layer 2 for releasing is formed on the single-crystal silicon substrate 14, and on the porous silicon layer 2, the thin-film single-crystal silicon layer 13 is epitaxially grown.
