    摘要: A method of fabricating a waveguide device is disclosed. The method includes providing a substrate having an elector-interconnection region and a waveguide region and forming a patterned dielectric layer and a patterned redistribution layer (RDL) over the substrate in the electro-interconnection region. The method also includes bonding the patterned RDL to a vertical-cavity surface-emitting laser (VCSEL) through a bonding stack. A reflecting-mirror trench is formed in the substrate in the waveguide region, and a reflecting layer is formed over a reflecting-mirror region inside the waveguide region. The method further includes forming and patterning a bottom cladding layer in a wave-tunnel region inside the waveguide region and forming and patterning a core layer and a top cladding layer in the waveguide region.

    摘要: The present disclosure is directed to a method of manufacturing an interconnect structure in which a low-k dielectric layer is formed over a semiconductor substrate followed by formation of a copper or copper alloy layer over the low-k dielectric layer. The copper or copper alloy layer is patterned and etched to form a copper body having recesses, which are then filled with a low-k dielectric material. The method allows for formation of a damascene structures without encountering the various problems presented by non-planar features and by porus low-K dielectric damage.

    摘要: The present disclosure provides a method for fabricating an integrated circuit. The method includes forming an energy removable film (ERF) on a substrate; forming a first dielectric layer on the ERF; patterning the ERF and first dielectric layer to form a trench in the ERF and the first dielectric layer; filling a conductive material in the trench; forming a ceiling layer on the first dielectric layer and conductive material filled in the trench; and applying energy to the ERF to form air gaps in the ERF after the forming of the ceiling layer.
