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.

However, in such conventional reticle creation methods, in the exposure data creation process, if one chip has the same area or multiple reticles have the same area, the same cell part must be processed redundantly. Because of this, as in recent years, as the data capacity of a single chip has increased and a number of functions have been added to a single chip, the number of steps required in the exposure data creation process has increased. , and the amount of exposure data becomes enormous. In particular, as chips become larger, reticle exposure itself may not be possible in some cases due to limitations in the capacity of the exposure apparatus.
