Abstract:
A process for fabricating an electro-optic device comprising:providing a first substrate having a first layer of semiconductor material and a second layer of semiconductor material separated by a layer of an oxidized semiconductor material;forming a cavity in the first layer of semiconductor material wherein the cavity terminates at the layer of oxidized semiconductor material;defining a mirror element in the second layer of semiconductor material wherein the mirror element has a location in the second layer of material that corresponds to the location of the cavity in the first layer of material and wherein the mirror element has first and second major surfaces;removing the layer of oxidized material between the mirror element and the cavity;providing a second semiconductor substrate having electrodes formed thereon; placing the first substrate in contact with the second substrate so that the electrodes on the second substrate are under the mirror element in the first substrate and disposed in the cavity in the first substrate; andbonding the first substrate to the second substrate.
