Title: Manufacture of semiconductor element
Inventor: MURAKAMI KENTARO
IPC: H01L21/329
Filed: 1985-10-31
Abstract: PURPOSE:To decrease the forward saturation voltage and thermal resistance without deteriorating the dielectric strength, by forming a recess on one surface of a semiconductor substrate before epitaxially growing a semiconductor layer on said surface. CONSTITUTION:An N<+> type semiconductor substrate 6 having a thickness of T1 is etched in the central portion of its principal face 6a to a depth of D1. When an N<-> type semiconductor layer 7 is epitaxially grown thereon to have a thickness of D2, a recess 7a is formed on its surface corresponding to the etched recess 6b in the substrate 6. The semiconductor layer 7 is sliced along the bottom of the recess 7a so as to flatten the surface of the layer 7. After that, a P-type semiconductor layer 8 is formed in a region of the epitaxial layer 7 corresponding to the etched recess 6b. In a planar diode 9 thus provide, the thickness T1 of the substrate 6 and the thickness D2 of the epitaxial layer 7 are substantially unchanged in comparison with prior arts. However, the thickness of the epitaxial layer 7 is increased by D1 in the region corresponding to the region where the P-type semiconductor layer 8 is to be formed. Therefore, the dielectric strength can be improved without increasing the forward saturation voltage or thermal resistance.

Abstract: PROBLEM TO BE SOLVED: To improve air temperature dependency and mechanical strength by constituting electrical heating and temperature-sensing resistors with a dope-treated polycrystalline silicon semiconductor thin film and setting the impurity concentration of the electrical heating resistor at least at a specific value and increasing it as compared with that of the temperature-sensing resistor. SOLUTION: Electrical heating resistors 4a and 4b have larger impurity concentration, at least 3×10<19> cm<-3> , for temperature-sensing resistors 5 and 6. The voltage of terminals F and G of a bridge circuit including the temperature-sensing resistors 5 and 6 and resistors 25b and 25c is inputted to a control circuit 26, and a temperature Th of the temperature- sensing resistor 5 heated by the electrical heating resistors 4a and 4b is controlled to be higher than a temperature Ta of an air temperature-sensing resistor 6 by a constant value by the control circuit 26. When the temperature of the temperature-sensing resistor 5 is lower than a set value, a transistor 24 is turned on and a heating current flows to the electrical heating resistors 4a and 4b. When the temperature becomes high, the transistor 24 is turned off.  The heating current value of the electrical heating resistors 4a and 4b is an air flow rate. On the other hand, the direction of an air flow can be detected by comparing the temperatures of the electrical heating resistors 4a and 4b, thus achieving an accurate flow detection for detecting the direction of the air flow without being affected even if an air temperature changes.
