Abstract: In a semiconductor integrated circuit device such as a memory chip, the number of wirings is increasing as the memory capacity and the like increase. In improving the reliability and obtaining high access speed of a common bus in which these wirings are arranged, wirings in a second layer and via holes at jumpers used for interference portions of signal wirings and power supply wirings in a congested region of a common bus have become an issue. Accordingly, in the present invention, it is made possible to form wirings in the second layer having wide width and a plurality of via holes per one connecting point, thus realizing a semiconductor integrated circuit which has high reliability and high access speed by arranging a mother power supply wiring branched to the common bus line along the vicinity of processing circuits of signal wirings arranged in the common bus.
Abstract: Drift values of exposure position of an electron beam are obtained through detection of a reference mark on a sample stage and a drift characteristic formula which expresses the exposure positions of the electron beam is corrected by using a plurality of the drift values. The electron beam is controlled to expose some lithographic pattern by estimating the exposure position in real time at which the electron beam is irradiated at the estimated exposure position based on the drift characteristic formula without detecting the reference mark, and further to expose other lithographic pattern by calculating the exposure position based on the drift characteristic formula by detecting the reference mark. The measuring of the drift which takes much time are partly taken place at few limitted positions and the correction of the exposure positions is effectively in a short time.
