A economical X-ray conformal mask manufactured by using a dry film pro
cess is reported. The dry film (HITACHI H-N650) is used as the photore
sist in the photolithography process. Tin/lead and gold were electropl
ated as the X-ray absorber. The feasibility and limitations of the dry
film process were addressed. Using this X-ray conformal mask in X-ray
lithography, 1000 mu m thick PMMA microstructures were achieved to de
monstrate the fidelity of this method.
