Here, the holding plate has a plurality of non-contact surfaces which come into contact with the substrate. At a noncontact part, a space is formed between the substrate and the holding plate and no surface tension is generated. The noncontact part, therefore, has a function of adjusting the holding force of the holding plate for the substrate. Namely, a proper number of contact parts of proper size are formed on the holding plate while the weight of the substrates to be held is taken into consideration, so the substrates are stably held and separated from the holding plate with a proper force, so that the substrates themselves will neither be fouled nor damaged.  <P>COPYRIGHT: (C)2004,JPO
