发明名称 Mask for an exposure process using X-ray
摘要 A fabrication process for a mask used in exposure processes using x-rays, which includes first forming and patterning an absorber, and then forming a membrane over it. The fabrication process can avoid the use of a selective etching process on the absorber and the membrane. The mask, according to the invention, can prevent transferred pattern misalignment or displacement or misplacement, and exposure to secondary electrons as well.
