IPC: G03F1/68
Filed: 1988-11-21
Abstract: PURPOSE:To reduce the moves and capacity of exposure data preparation and to correspond to an enlarged chip by dividing design data according to the region by converting it to exposure data, and by performing exposure based on the exposure data which is divided and made according to each region. CONSTITUTION:Coordinates information of a pattern 1 is divided to each part of a cell part A, a cell part B and a cell part C and input to a computer, which processes exposure data of each cell part through batch conversion to make exposure data of each cell part. Then, in an exposure process, arrangement and exposure are performed based on each exposure data to complete whole reticle. Therefore, treatment is performed for a mask design pattern by dividing it according to the part to reduce a process which was repeatedly carried out in a process of data preparation. It becomes possible to reduce the moves of a process largely by carrying out parallel operation through a computer during conversion.

Filed: 1986-12-10
Abstract: PURPOSE:To attain effective utilization of the hardware resource and the high speed processing by providing a register feeding back a partial product by a fixed coefficient multiplier and storing the intermediate result of each step, and adding a logic detecting whether or not an output symbol is '0' element and a logic switching two kinds of functions of a general multiplication and a calculation of an error location polynomial. CONSTITUTION:A coefficient of each order number of an error location polynomial is stored in registers 16-18 by setting a switch logic gate circuit 14 to an input side not being the feedback position. A switch logic gate circuit 15 switches an output of a pipeline register 13 and outputs of the registers 16-18 storing the feedback value of an intermediate value being the result of multiplication of fixed coefficients from a<o> to a<t> and substitution of position number of the error location polynomial. Then, the switch logic gate circuit 14 is thrown to the feedback position and the feed back is repeated by a step number corresponding to the code length (n) and a '0' element detection circuit 11 obtains roots of the error location polynomial. Thus, many parts of multipliers being a part of the Galois field arithmetic unit are used to obtain roots of the error location polynomial and the arithmetic operation is processed at a high speed.
