Abstract
A method for opposing a sheet-like material to a standard plane with predetermined space therebetween, which method when applied to a non-contact (proximity) printer such as one of IC and LSI construction, can improve the efficiency of the printing operation. The method comprises two sub-steps of a preparation step and a step for actually opposing the sheet-like material to the standard plane; the preparation step is done where no standard plane is present and in the preparation step the space or distance between a sub-standard plane having a predetermined relation with the standard plane and the sheet-like material on a carrier is measured and the measured value is memorized. After the completion of the preparation step, the sheet-like material is transferred together with the carrier to the position at which the standard plane is present, and then the memorized value is reproduced and the position of the carrier is determined in respect to the standard plane on the basis of the reproduced value used as a factor, thereby the distance between the surface of the sheet-like material and the standard plane corresponds to the predetermined value.
