Patent JP-H06291069-A (JP)
Title: Semiconductor manufacturing equipment and heat processing method for semiconductor substrate using it
Inventor: KUROISHI KENICHI
IPC: H01L21/26
Filed: 1993-04-02
Abstract: PURPOSE:To prevent the occurrence of crystal distortion within semiconductor substrates by preheating a semiconductor substrate with implanted impurities using a first heating means at temperatures below a point at which the impurities start diffusion, and subsequently diffusing the impurities in the substrate using a second heating means. CONSTITUTION:The interior of a quartz chamber 17 is preheated using a first heating means 13 composed of a resistance heating heater. The preheating temperature is set to a value slightly below the diffusion start temperature of an impurity implanted into a semiconductor substrate 11. If boron is to be implanted into the semiconductor substrate 11, for example, the temperature is set to 780 deg.C; if phosphorus is to be implanted, 800 deg.C is selected. Thereafter, the substrate 11 is heated using a second heating means 15 at a temperature higher than the preheating temperature to diffuse the implanted impurities. The time of heating by the second heating means 17, composed of an instantaneous heating heater, should be approx. 10 sec. This prevents the occurrence of crystal distortion within a semiconductor substrate and leakage current of diffusion layers.

IPC: H03H3/08
Filed: 1988-04-20
Abstract: PURPOSE:To manufacture a surface wave device less influenced by a reflected wave at a substrate end part by heating a part corresponding to an area other than the effective propagation area of a surface wave after the whole surface of a substrate is polarized, and making the degree of polarization of said part smaller than that of other part. CONSTITUTION:The area from an interdigital transducer(IDT) 14 to the IDT 16 including parts of the IDTs 14 and 16 is made to be the effective propagation area A of the surface wave, and the area other than it, i.e., the areas from each of the IDTs 14 and 16 to the opposing end parts of a piezoelectric substrate 12 are made to be the areas B other than the effective propagation area, and the area A is polarized so as to make the degree of polarization necessitated for the propagation of the surface wave, and the area B is either polarized so as to make the degree of polarization much smaller than that of the area A or is not polarized at all. Thus, the influence of the reflected wave can be widely reduced. For this purpose, a ceramic wafer 26 is polarized so as to make the degree of polarization necessitated for the area A extending over its whole surface. Next, the part corresponding to the area B is heated by a heating tool 28 so as to reduce the degree of polarization of the part corresponding to the area B.

Abstract: PROBLEM TO BE SOLVED: To provide the data processing unit by which an output to a terminal is surely conducted even when an output system of an output terminal differs even in the case that an image received via a line is outputted from other terminal on a LAN. SOLUTION: When a facsimile equipment 101 receives an incoming call, the facsimile equipment 101 detects and analyzes a Caller.ID. When the facsimile equipment 101 cannot detect it, an output printer is set. When the facsimile equipment 101 can detect it, a printer with a printer number corresponding to the telephone number registration is set as an output printer (S604). When the reception processing is finished (S605), whether or not the set output printer has a printer number 0 is discriminated, and when the prier number is number 0, an output is made to a printer of the facsimile equipment and the processing is finished (S607). In the case that the printer other than the number 0 is set, the received document is converted into an image suitable for capability of the registered printer and the converted image is transferred to an object printer on a LAN (S608, S609).

Title: Detecting device of disconnection or short circuit
Inventor: YAMAMOTO KIYOSHI
IPC: G01R31/50
Filed: 1981-06-24
Abstract: PURPOSE:To reduce a manufacturing cost of a device, by constituting it so that a state of one test signal detecting terminal which forms a pair can be discriminated by sending out a test signal from one test signal sending-out terminal. CONSTITUTION:In case when a circuit to be inspected is normal, when a test signal of a low level is sent out from a test signal output terminal 1, the signal reaches a test signal detecting terminal 5 through a pin 2. Accordingly, both the signal sending-out terminal and the signal detecting terminal 5 are in a low level and coincide with each other. In case when the circuit to be inspected has been disconnected, the test signal of a low level does not reach the signal detecting terminal 5. Accordingly, when the test signal of a low level is being sent to the signal sending-out terminal, disconnection can be detected by deciding a level of the signal detecting terminal 5 forming a pair. According to such a constitution, since the circuit configuration can be simplified, the manufacturing cost can be reduced.
