Title: Device for drawing picture by the use of ion beam
Inventor: SAWARAGI HIROSHI
IPC: H01L21/265
Filed: 1985-04-18
Abstract: PURPOSE:To facilitate controlling the focusing of the ion beam by using the first deflector, which consists of elements for deflecting the beam to opposite directions, to irradiate the beam upon a drawing material and by using the second deflector to vary the incidence position of the beam. CONSTITUTION:The beam discharged from an ion source 11 and containing impurity ions is focused and poured on a drawing material 14 such as a silicon wafer. In order to prevent the impurity ions from penetrating deep into the material 14, a first deflector 18 consisting of electrostatic deflecting plates 20 and 21 to which opposite voltages are applied from a deflection power supply 22 is used to make the beam to be obliquely (for example, 7 deg.C slant from the axis) irradiated upon the material 14. The incidence position of the beam is varied by feeding deflecting signals for the figure of a picture to be drawn from a deflecting circuit 23 to a second deflector 19. Accordingly, it is possible to easily focus the beam and to prevent any blur of the beam which might result from dispersion of the ionic energy.

Title: Clock crossover circuit
Inventor: HAZAMA HISAMICHI
IPC: G06F1/04
Filed: 1988-04-05
Abstract: PURPOSE:To obtain a difference in the crossover timing by blocking the passing in the presence of an abnormality in the period of a load pulse and using an AND so as to gate a pulse whose count period is made coincident and an output of a NAND. CONSTITUTION:A load pulse M to be inputted is NANDed by an E pulse at a NAND 1 to block the passing in the presence of the abnormality in the period of the load pulse M. Moreover, the period is made coincident with the count period of an F pulse and the F pulse and an output of the NAND 1 are ANDed by an AND 2. As a result, a b-adic counter 3 is loaded by the load pulse M when the clock crossover is normal and the counter is loaded by the F pulse when the clock crossover is abnormal. Thus, the crossover function of the two clock frequencies different from each other is realized by a minimum circuit constitution.

Filed: 1986-04-11
Abstract: PURPOSE:To reset a comb-shaped digital filter which is constituted by using a delay element provided with no reset terminal by using a counter, a reset circuit, and a switch circuit. CONSTITUTION:When a reset signal (e) is inputted to the counter 15, the counter 15 starts (n)-stage counting operation and outputs a counter output signal (f) to the reset circuit 16. When the (n)-stage counting operation is finished, the counter 15 finishes its operation and stops, and also finishes outputting a counter output signal (f). The reset circuit 16 outputs the reset signal (g) to an output control circuit 13 for clearing the output signal D of the switch circuit 12 while the counter output signal (f) is inputted. While the reset signal (g) is inputted to an output control terminal 13, the switch circuit 12 does not pass the output signal C of a delay element 11 and a signal which is cleared is outputted as the output signal D of the switch circuit 12. Consequently, the comb-shaped digital filter which uses the delay element having no reset terminal can be reset.
