Title: Semiconductor device
Inventor: KANEKO SHINJI
IPC: H01L27/06
Filed: 1989-01-26
Abstract: PURPOSE:To form a bipolar element of high breakdown strength and a fine MOS element into an integral structure by a method wherein a depletion layer is made to spread enough when a junction between a base and a collector of a bipolar transistor is reversely biased, and a drain depletion layer is restrained from spreading. CONSTITUTION:An N<+> layer 2 and a P<+> layer 3 are selectively buried in a P-type Si 1 of 1X10<15>cm<-3>, and an N-epitaxial layer 4 of 1X10<13>cm<-3> is laid thereon. A B ion implanted layer 15 and a P ion implanted layer 14 are formed in a P-well region and an N-well region respectively. The P-type Si 1 is treated in an N2 atmosphere at a temperature of 1050 deg.C for eight hours to form a P-well 5 and an N-well 6. As the N-well 6 is formed shallow, when a bipolar element is formed and a junction between a base and a collector is reversely biased, a depletion layer is made to spread enough easily inside the epitaxial layer 4 of low impurity concentration, so that the bipolar transistor can be improved in breakdown strength. On the other hand, a MOS element inside the P-well 5 operates at a high speed restraining a short channel, because a depletion layer is prevented from spreading wide when a junction between a drain and the well 5 is reversely bias as the concentration of the well 5 is larger than that of a drain.

Abstract: PURPOSE:To suppress leanness of air-fuel ratio while preventing promotion of a pulsation by canceling only high frequency delay correction when a low frequency delay correction amount is a positive value, at the time of high load easily generating an intake pulsation. CONSTITUTION:In a temperature sensing flow meter, by assuming QA for intake air flow detection value, QA-1 for preceding time detection value and AFMTC>1 for constant, a high frequency delay correction amount Qss= QA-1+(QA-QA-1)XAFMTC is calculated. By assuming QSS-1 for preceding time arithmetic value of Qss and AFLEG, AFLETC(<1) for constant, a low frequency delay correction amount AFLE=(Qss-QSS-1)XAFLEG+AFLE-1XAFLETC is obtained to output Qs=Qss+AFLEXAFLEA as a measured value. On the other hand, at the time of high load where a throttle valve opening theta=theta0 (theta0 is predetermined opening of throttle valve easily generating intake pulsation), when a relation is AFLE>0, high frequency delay correction is canceled to obtain a measured value suited for a request value.
