Abstract
A method of manufacturing a liquid crystal optical device such as a lens, a beam steering device or an optical image stabilization device is described. The method includes edge bonding a thin substrate onto a carrier substrate to obtain a combined substrate; manipulating the combined substrate by the carrier substrate for wafer level fabricating at least one liquid crystal optical device on the central portion of the first thin substrate. Each liquid crystal optical device includes liquid crystal cell walls. To form the at least one liquid crystal optical device a second thin substrate is provided and bonded to the combined substrate. The cell walls support and interconnect the thin first substrate to the second thin substrate. The at least one liquid crystal optical device is singulated by dicing the combined substrate within the peripheral bonding zone.
