Patent JP-S63142833-A (JP)
Title: Manufacture of semiconductor device
Inventor: MORIYAMA MASATOSHI
IPC: H01L23/52
Filed: 1986-12-05
Abstract: PURPOSE:To increase inner aluminum in grain boundary or to form a state completely free of grain boundary by quickly heating or cooling a wiring- patterned aluminum layer to form only the surface and the sidewall of the aluminum wiring layer in an amorphous state. CONSTITUTION:Aluminum wiring-patterned semiconductor substrate is placed in a reduced pressure inert gas atmosphere on a high concentration semiconductor layer. Then, free carrier absorption is executed by using infrared ray of long wavelength for the semiconductor layer of a semiconductor substrate 1 and aluminum wirings, only the aluminum layer is heated to quickly heat it to the vicinity of the melting point 1 of the aluminum (approx. 650 deg.C). Since the long wavelength is used, the substrate is not substantially accelerated. When the heating is stopped, inert gas is simultaneously sprayed to the substrate to rapidly cool it to room temperature 2. The time required for this quick heating and rapid cooling is approx. 1 sec. Since only the surface of the aluminum wirings and the sidewall are formed in an amorphous state, high current density resistance can be improved while high purity aluminum wirings remain unchanged.

Abstract: PURPOSE:To detect abnormality in an equipment and change with time the lapse of by providing a sensor for detecting the physical property of a sealed liquid at a part where the sealing flow of a differential pressure transfer equipment is housed for monitoring the output of the sensor. CONSTITUTION:When a small crack or a void occurs in liquid-contact diaphragms 114a and 114b of a differential pressure transfer equipment due to damage caused by corrosion etc., a process fluid penetrates or is diffused into a sealed flow 120 inside pressure-reception chambers 126a and 126b. Therefore, change in physical property occurs in the liquid 120 so that its specific dielectric constant also begins to change. At this time, the between parallel flat-plate capacitors of the physical property change detection sensors 150a and 150b provided inside the pressure reception chambers 126a and 126b simultaneously changes. The capacitance change is sent to a signal processing circuit 122 via insulation terminals 132 and 131 and is converted to electrical signal, thus allowing the differential pressure transfer equipment itself to detect that the diaphragms 114a and 114b are damaged or failed rapidly and also an upper- level instrumentation equipment controlling the differential pressure transfer equipment to detect it.

Abstract: PURPOSE:To prevent the expansion in a circuit scale even if the number of channels of signals is increased by adding or subtracting a digital value which has a constant value to or from a digital signal outputted from a RAM circuit and inputting the resulting signal to the RAM circuit again. CONSTITUTION:A coefficient and an addition/subtraction level value which are outputted from the RAM circuit 12 are inputted to an adding/subtracting circuit 11 and the addition or subtraction of those two values is carried out by the command of a data selector circuit 14.

Namely, the certain value is added to or subtracted from the coefficient outputted by the RAM circuit 12 to generate the new coefficient, which is inputted to the same address of the RAM circuit 12 again to replace the coefficient with the new coefficient. Consequently, even when the number of channels of signals can be increased without increasing the capacity of the RAM circuit and the circuit scale is never increased in proportion to the number of channels.

A decision is made whether the record data of the pixel of interest is based on code information at S5 and if the record data is based on code information, the flow advances to S6 where a decision is further made whether the record data of adjacent pixel is based on code information. If the answer is YES, the flow advances to S7 where a decision is made whether the adjacent pixel has same color as the pixel of interest. When the answers at S6, S7 are YES, the flow advances to S8 otherwise advances to S9 where the adjacent pixel is processed as a non-delivery data regardless of the recording data thereof.
