Title: Method for measuring thickness of silicon wafer
Inventor: FUJISAWA KAZUO
IPC: G01B17/02
Filed: 1981-10-30
Abstract: PURPOSE:To measure the thickness of a silicon wafer with a high precision, by forming a recessed part on a face, to which the silicon wafer should be stuck, to prevent the transmission of ultrasonic waves and obtaining a regular multiple reflection echo. CONSTITUTION:A round recessed part 4a is formed preliminarily on the surface of hih polymer materials 4, to which a silicon wafer 7 should be stuck, of an attaching surface plate 6. The silicon wafer 7 is stuck to high polymer materials 4 so as to cover the recessed part 4a, and a probe 8 is used to measure the thickness of the silicon wafer 7 by the ultrasonic pulse reflection method. By forming this recessed part 4a, almost all incident ultrasonic waves are reflected on a face S1 because air in the recessed part 4a and the silicon wafer are different in acoustic impedance very much. As a result, transmitted echoes shown in figure by 2, 4, and 5 are not superposed to multiple echoes, and regular multiple reflection echoes are obtained. By this way, the obtained measurement precision is + or -2mum, and the thickness measured with a very high precision.

Title: Semiconductor device
Inventor: FURUHATA TOMOYUKI
IPC: H01L29/73
Filed: 1988-07-12
Abstract: PURPOSE:To allow an impurity concentration in an external base region to be higher than that of an intrinsic base region and lower a base resistance rbb' without decreasing hFE, thereby realizing a high speed operation of elements which are superior in high frequency characteristics by forming the first and second base regions of a bipolar transistor separately. CONSTITUTION:The second base region 4b is formed so that the diffusion depth of impurities is deeper than that of the first base region 4a and even its concentration is higher than that of the first base region 4a because of p-type impurities diffused from a base electrode 7 consisting of a p<+> type polycrystalline Si layer. The first and second base regions 4a and 4b of a bipolar transistor are formed separately. Since an impurity concentration of the second base region 4b can be higher than that of the first base region 4a, this device makes a base resistance rbb' low without giving rise to lowering of hFE and improve the operating speed of the transistor.

Title: Serial interface circuit
Inventor: IWAMOTO SHINICHI
IPC: G06F9/52
Filed: 1989-07-05
Abstract: PURPOSE:To easily obtain a multi-master system by adding a command/bus release signal detecting circuit. CONSTITUTION:A command/bus release signal detecting circuit 8 detects and transmits a bus release signal having a rise edge and a command signal having a fall edge on a data line asynchronously with a clock line. A counter 12 makes a shift register 9 perform a shift action with a serial clock and at the same time inhibits the transmission of the serial clock to the clock line to produce the bus release and command signals for detection of a 1st time covering the command signal through the bus release signal and a 2nd time following the 1st time through the command signal. Then a signal pattern decided by the 1st and 2nd times is properly assigned to a microcomputer. Thus it is possible to decide the master one among plural microcomputers and to decide whether the serial data transferred should be carried out or not after the transfer of an address code.

A post slope surface sensor 14 is fixed with the upper end of each lift support 4 where a post upward projection length sensor 15 is upwardly mounted in an upper part combination member 10. Detection signals from both sensors are incorporated into a control device 17, thereby determining the amount of horizontal deviation produced by the inclination posts at the paired upper and lower guide rollers 11a and 11b. Then, the posts are automatically adjusted so that they may be located at an inclination zero position of the posts by the drive system of the paired upper and lower guide rollers. The pots 4 are driven downward so that they may be rightly fitted in a main designed post 1a.
