Title: Multiplier circuit
Inventor: TAHIRA YOSHIHIRO
IPC: G06F7/52
Filed: 1990-03-08
Abstract: PURPOSE:To reduce the number of circuit elements by transforming a polarity amplitude display input from amplitude attribute display to the complementary display of 2 and obtaining the result of multiplying two inputs by the complementary display of 2. CONSTITUTION:In order to transform the polarity amplitude expression to the complementary expression of 2, it is enough to exclusively OR X3 as MSB and a bit excepting for the MSB and to add the X3. Out of signals 21 of X input terminals X3-X0, signals X2-X0 excepting for the MSB and the X3 are exclusively ORed by logic gates 22-24 and outputs A2-A0 are obtained. Further, by adding the signal X3 to a carry input Ci of an M cell 32 as the M cell of the least significant bit to obtain the partial product of a multiplier, the signal of the polarity amplitude display can be transformed to the signal in the display of 2. Thus, since multiplication can be executed by the complementary display of 2 in a multiplier part 25 using Booth algorithm with X3 and A2-A0 as X inputs and Y3-Y0 as Y inputs, the number of circuit elements can be reduced.

Filed: 1980-04-28
Abstract: PURPOSE:To enable to test the address access time and address decoder function correctly, by repetitively making the data readout from the background address in ping-pong system while changing the reference address. CONSTITUTION:When the number of read times is set to the number of read time control circuit 1, the control circuit 4 gives the instruction signal to the mode control circuit 3 and the selector gate 6 and writes in the data D to all the addresses of the address counter 2-A. Next, the address (i) (reference address) is set to the address counter. Further, the data D is written in the address (i). The address i+1 is set to the counter 2-B to make n-time readout operation from the address i+1. Further, the readout of the address (i) of the counter 2-A is made and the counter 2-B is made to +1 and this is repeated. The circuit 4 receiving the signal in agreement with the content of the counters 2-A and 2-B from the comparison circuit 5-A, makes the counter 2-A by +1 and the entire processings are repeated.

Title: Control system for electron beam lithography
Inventor: KAI JUNICHI
IPC: H01L21/66
Filed: 1986-03-14
Abstract: PURPOSE:To prevent an electron beam from being applied to a position outside a target by a method wherein the clock of a sample position control system is nullified in synchronization with the basic clock pulse of an electron beam deflection control system and, in that state, the sample position measurement data are taken in to calculate a pattern correction quantity and the nullified state of the clock is released by the time the next pulse comes. CONSTITUTION:CLK 0 is the basic clock of an electron beam deflection control system and the calculation of the deflection quantity of the electron beam application and blanking control are carried out in accordance with the clock. The basic clock of a distance measurement system is different from that clock. Thereafter, if DELTAX is outputted at any time regardless to CLK 0, inconvenience is created. Then, CLK 1, which is obtained by delaying CLK 0 by the time (t1) and CLK 2, which is obtained by delaying CLK 1 further by the time (t2) are generated and the clock of the distance measurement system is nullified by CLK 0 and made effective again by CLK 2. During the nullified period, a latching signal synchronized with CLK 1 is created and the content of a DELTAX holding register is latched. As the electron beam deflection control system performs calculation of pattern correction by taking this latched error DELTAX, misuse of data which is in the process of rewriting can be avoided.
