  • Patent number: 10748781
    Abstract: A method of catalyst-assisted chemical etching with a vapor-phase etchant has been developed. In one approach, a semiconductor substrate including a patterned titanium nitride layer thereon is heated, and an oxidant and an acid are evaporated to form a vapor-phase etchant comprising an oxidant vapor and an acid vapor. The semiconductor substrate and the patterned titanium nitride layer are exposed to the vapor-phase etchant during the heating of the semiconductor substrate. The vapor-phase etchant diffuses through the patterned titanium nitride layer, and titanium nitride-covered regions of the semiconductor substrate are etched. Thus, an etched semiconductor structure is formed.

  • Patent number: 10741705
    Abstract: An optoelectronic device with an antireflective surface comprises a semiconductor substrate having a textured surface including a plurality of surface protrusions and/or indentations. A first electrode is in contact with the semiconductor substrate and spaced apart from a second electrode that is also in contact with the semiconductor substrate. The textured surface is fabricated by inverse metal-assisted chemical etching, and thus the semiconductor substrate is substantially devoid of ion-induced defects.

  • Publication number: 20190234256
    Abstract: Disclosed herein are an oil pump control valve and, specifically, an oil pump control valve allowing a discharge port and the inside of a solenoid part to communicate with each other through a spool so as to relieve pressure inside the solenoid part. A spool flow path, a vent hole, and a spool notch are formed so as to allow the solenoid part to communicate with the outside regardless of the flow of fluids when the valve is operated, thereby enabling the internal pressure of the solenoid part to be relieved. In addition, the spool and a rod are integrated such that the axial misalignment of the spool can be prevented and a holder has different diameter such that the flow of fluids can be controlled even during an abnormal power shutdown.

  • Patent number: 10134599
    Abstract: A method of metal-assisted chemical etching comprises forming an array of discrete metal features on a surface of a semiconductor structure, where each discrete metal feature comprises a porous metal body with a plurality of pores extending therethrough and terminating at the surface of the semiconductor structure. The semiconductor structure is exposed to an etchant, and the discrete metal features sink into the semiconductor structure as metal-covered surface regions are etched. Simultaneously, uncovered surface regions are extruded through the pores to form anchoring structures for the discrete metal features. The anchoring structures inhibit detouring or delamination of the discrete metal features during etching. During continued exposure to the etchant, the anchoring structures are gradually removed, leaving an array of holes in the semiconductor structure.
