发明名称 Antistatic conductive pin mounting apparatus for a photomask
摘要 In an antistatic apparatus for a photomask including a conductive optical shield layer, at least two conductive pins are inserted into the photomask, so that the conductive pins are in contact with the conductive optical shield layer. Then, the photomask is set in a cassette of an electron beam exposure apparatus. Then, the conductive pins are electrically connected to the cassette by conductive plates. Thus, electrons charged at the conductive optical shield layer by electron beams are effectively discharged from the conductive pins to the cassette.
