Abstract: PURPOSE:To improve the reverse withstand voltage of a semiconductor device and to prevent crack of the substrate thereof by forming shallow depth of an isolation layer on a main surface exposed with the PN-junction of a substrate and connecting it with deep isolating layer from the back surface. CONSTITUTION:An SiO2 film 2 is coated on an N<-> type Si substrate 1 having high thickness and large-diameter opening, an opening 2b is perforated at one main surface, and a P type isolating layer 11a having a depth larger than the half of the thickness of the substrate 1 is formed. Then, an opening 2c is perforated at the confronting position with the back surface, the SiO2 film 2 on the surface is removed, and a P type emitter layer 4 and a P type isolation layer 11b connected to the layer 11a are formed thereon. Thereafter, a P type base layer 5 and an N+ type emitter layer 16 are formed as conventionally, electrodes are attached thereto, and the layer 11 is cut at the center. A sufficient depletion layer 12 extended to the N type base layer 7 is created by the shape of the isolation layer according to this configuration enough to enable retension of high reverse withstand voltage. When the P type layer 4 is formed thicker than the conventional one, it is difficult to crack and enables use of the substrate having large bore merely by increasing slightly the ON voltage.

IPC: G01K3/00
Filed: 1985-05-14
Abstract: PURPOSE:To perform the measurement of temp. at a high speed with high accuracy, by displaying the max. temp. as a peak value when the detected temp. after a predetermined time was elapsed is a predetermined value or more. CONSTITUTION:A max. value detection part 20 compared temp. data inputted in a time series manner and employs a larger data value to detect a first max value P1. A timing part 40 begins to measure a predetermined time t1 from the beginning every when a value larger than the max. value p1 is detected for the time t1. When a peak value P2 is detected by this method, the value P2 is renewed as the max. value on and after. In the same way, the timing of t1 is newly started from this time and, when the temp. P3 at a time S1 after the elapse of t1 is larger than a predetermined value TL, a normal peak value detection part 50 displays the peak value temp. P2 on a display device 60. By this method, a measuring time is shortened.

Abstract: PURPOSE:To detect accurately the dry state, the wet state, th snowy state, the frozen state, etc. of the road surface even if vehicles come, by projecting visible rays and infrared rays to the road surface and discriminating respective photodetection levels of the regular reflection light and diffused reflection light of visible rays and the diffused reflection light of infrared rays. CONSTITUTION:Visible rays and infrared rays are projected to a road 21 from a mercury-arc lamp 24, and reflection lights are received by a regular reflection light receiver 26 and a diffused reflection light receiver 25. The temperture of the road surface is measured by a radiation thermometer 28, and the quantity of projection light of the mercury-arc lamp 24 is measured by a projection light quantity level measurer 27. In respect to reflection lights, the regular reflection light of only visible rays is received, and diffused relfection lights of visible rays and infrared rays are received individually. The state of the road surface is discriminated by the overall judgement of these quantities of received light and the temperature of the road surface. In case that a vehicle comes, three factors, namely, rapid reduction of the regular reflection light of visible rays, rapid increment of the diffused reflection light of visible rays, and lowering of the output of the thermometer for the road surface are discriminated.
