ON-CHIP DIFFRACTION GRATING PREPARED BY CRYSTALLOGRAPHIC WET-ETCH |
摘要 |
Methods of forming microelectronic structures are described. Embodiments of those methods may include forming a photomask on a (110) silicon wafer substrate, wherein the photomask comprises a periodic array of parallelogram openings, and then performing a timed wet etch on the (110) silicon wafer substrate to form a diffraction grating structure that is etched into the (110) silicon wafer substrate.
