Cutting Diffraction Gratings to Improve Dispersion ("Fire") In Diamonds
The Process. Microlithogarphy is a process by which a temporary coating (called a resist) is deposited onto a substrate, exposed to light or an electron beam, and developed (i.e., with a solvent that selectively removes the resist layer. The pattern is transferred onto the substrate by etching or by depositing another material. Microlithography is commonly used in the semiconductor industry for manufacturing integrated circuits.
