Claim 6:
7. A method of making an electronic part, comprising:
receiving an ultraviolet laser apparatus comprising an ultraviolet laser and at least one reflective mirror comprising a mirror substrate;
generating a laser beam with the ultraviolet laser; and
reflecting the laser beam with the at least one reflective mirror toward a precursor film to produce the electronic part;
wherein the mirror substrate is made from silicon carbide or an aluminum metal matrix composite, and has:
(i) an optical Figure of Merit (FoM) resonant frequency value of at least 6 relative to a fused-quartz substrate;
(ii) an optical FoM self-weight deflection value of less than 0.030 relative to a fused-quartz substrate;
(iii) an optical FoM steady-state thermal distortion coefficient value of less than 0.350 relative to a fused-quartz substrate; and
(iv) an optical FoM transient thermal distortion coefficient value of less than 0.600 relative to a fused-quartz substrate.
