  • Publication number: 20180297324
    Abstract: A method of controllably bonding a thin sheet having a thin sheet bonding surface with a carrier having a carrier bonding surface, by depositing a carbonaceous surface modification layer onto at least one of the thin sheet bonding surface and the carrier bonding surface, incorporating polar groups with the surface modification layer, and then bonding the thin sheet bonding surface to the carrier bonding surface via the surface modification layer. The surface modification layer may include a bulk carbonaceous layer having a first polar group concentration and a surface layer having a second polar group concentration, wherein the second polar group concentration is higher than the first polar group concentration. The surface modification layer deposition and the treatment thereof may be performed by plasma polymerization techniques.

  • Publication number: 20170352553
    Abstract: Methods of forming vias in substrates having at least one damage region extending from a first surface etching the at least one damage region of the substrate to form a via in the substrate, wherein the via extends through the thickness T of the substrate while the first surface of the substrate is masked. The mask is removed from the first surface of the substrate after etching and upon removal of the mask the first surface of the substrate has a surface roughness (Rq) of about less than 1.0 nm.

  • Publication number: 20140079087
    Abstract: A method of fabricating a laser diode structure is provided where a photolithographic process is utilized to form at least a portion of an axially extending waveguide structure such that a patterned photoresist remnant resides over the axially extending waveguide structure following the photolithographic process. A patterned isolated opening and a lift-off photoresist portion are formed in the patterned photoresist remnant by subjecting the patterned photoresist remnant to an additional photolithographic process such that the lift-off photoresist portion remains in residence over the axially extending waveguide structure following the additional photolithographic process. An insulating layer is formed over the patterned isolated opening and the lift-off photoresist portion.
