Abstract: PURPOSE:To remove the load of a CPU in the case of masking and processing the lower bits of an A/D converted result by providing an A/D converter mounted on an one-chip microcomputer with a shifting function. CONSTITUTION:When a CPU 9 specifies a shift specifying register 3 to 'H' through a data bus 6, a gate control signal 7 is turned to 'L' by an inverter 10 and gates 4 to which the signal 7 are inputted is turned off. On the other hand, a gate control signal 8 is turned to 'H' and gates 5 to which the signal 8 is inputted are turned on. Thereby, the upper two bits a3, a2 of an A/D converted result storing register A1 are inputted to the lower two bits b1, b0 of an A/D converted result storing register B2 and the upper two bits b3, b2 of the register B2 are turned to '0, 0'. When the CPU 9 reads out the contents of the register B2, the contents become '0, 0, a1, a0', so that a value obtained by masking the lower two bits of the A/D converted result can be read out.

Filed: 1985-10-25
Abstract: PURPOSE:To accurately measure the diffusion depth of impurities in a non- destructive manner by a method wherein, after impurities have been diffused, whether there exists electric continuity between diffusion layers formed on the windows having different intervals is measured. CONSTITUTION:The regions A in a semiconductor 1 are the regions where each semiconductor is formed, and the regions B are the regions to be used for the measurement of diffusion depth. On the regions A, a window is provided at the place corresponding to the part on the substrate surface of an N<+> layer 2b. On the regions B, seven windows 11-17 are formed in such a manner that the window-to-window interval is made wider gradually, and they are used as a mask 10. The part where an impurity diffusion layer is formed in the region A is an N-type semiconductor layer, but the part where an impurity diffusion layer is formed in the region B is a conductive P-type semiconductor layer. The depth of diffusion can be measured in a non-destructive manner by measuring the electric continuity of the diffusion layer of the adjoining windows, and as the presence of continuity is judged by the interposition of the P-N junction of an reverse series connection, the existence of conductivity can be discriminated clearly.
