Title: OPTICAL ASSEMBLIES INCLUDING A SPACER ADHERING DIRECTLY TO A SUBSTRATE
Abstract:
This disclosure describes optical assemblies that can be fabricated, for example, using wafer-level processes. The process can include providing a wafer stack that includes an optics wafer, and molding spacers directly onto the surface of the optics wafer. The spacers can be molded, for example, using a vacuum injection technique such that they adhere to the optics wafer without adhesive.
