Abstract:
A method of making a lithography stage structure, said method comprising the following steps:(a) providing a Ti doped SiO2 glass powder comprised of a plurality of particles of Ti doped SiO2 glass; (b) providing a binder, said binder for binding said Ti doped SiO2 glass particles together; (c) depositing a layer of said Ti doped SiO2 glass powder in a confined region to provide an underlying layer; (d) applying said binder to one or more selected regions of said layer of Ti doped SiO2 glass powder to bind at least two of said Ti doped SiO2 glass particles together to form a primitive, said applying binder bonding said glass powder together at said one or more selected regions; (e) depositing an above layer of said Ti doped SiO2 glass powder above said deposited layer; (f) applying said binder to one or more selected regions of said above layer with said binder bonding said glass powder together at said one or more selected regions; (g) repeating steps (e) and (t) a selected number of times to produce a selected number of successive layers with said binder bonding said successive layers together; (h) removing unbonded glass powder which is not at said one or more selected regions to provide a bonded Ti doped SiO2 glass powder lithography stage structure.
