IPC: G03F1/22
Filed: 1987-04-30
Abstract: A method of making a dimensionally stable mask suit­
able for use in X-ray lithography involves preparing a mask 
blank comprising a series of continuous laminae (4, 6, 8) 
which include a boron-doped epitaxial silicon barrier layer 
(6), which ultimately forms the support of an X-ray absorbing 
metal deposited thereon. This deposition is effected in such a 
way that the metal is chemically bonded to the boron-doped 
epitaxial silicon barrier layer (6) in the finished pattern it is to 
adopt. The underlying substrate (4), which comprises a 
silicon wafer on one surface of which the boron-doped 
eptiaxial silicon layer (6) is grown, is etched away from 
beneath this layer (6) either before or after the X-ray absor­
ber material (10) has been vapour deposited thereon.
