Abstract:
A process of fabricating a whispering gallery mode resonator structure in a bonded silicon wafer, said process comprising the steps of:a first masking etch step in which an SIO2 masking oxide forms holes in a bonded (SOI) silicon for subsequent deposition of epitaxial silicon to form a pedestal; a first deposition step entailing a deposition of epilaxial silicon to form a pedestal; a first etching step entailing etching away the SIO2 masking oxide to leave behind a pedestal structure; a second masking step in which SIO2 masking oxide defines a microdisk and moats for under etching the bonded (SOI) silicon for forming the whispering galley mode generator; and a second etching step which entails etching away the SIO2 masking oxide to leave behind the whispering gallery mode generator.
