Claim 12:
13. A method of fabricating a pixelated x-ray scintillator plate for high spatial resolution and high quantum efficiency x-ray detector, comprising:
a) Fabricate a Si micro-well matrix with desired pitch, depth and wall width;
b) Conformally coat multiple layers of materials to form a reflector with a thin metal layer (e.g. 100 nm Ru or W) to prevent cross talk between adjacent pixels; The thin metal layer is first conformally deposited via ALD, with a very thin (e.g. 2 nm) nucleation layer (e.g. Al2O3) pre-deposited via ALD if necessary; Then multiple dielectric layers are deposited via ALD to form the reflector,
c) Fill multilayer reflector coated micro-well matrix with the scintillator material.
