  • Patent number: 12165936
    Abstract: A method includes determining a target etching depth for etching a plurality of dielectric regions in a wafer. The wafer includes a plurality of protruding semiconductor fins and the plurality of dielectric regions between the plurality of protruding semiconductor fins. The method further includes etching the plurality of dielectric regions, projecting a light beam on the wafer, and generating a spectrum from a reflected light reflected from the wafer, determining an end point for etching based on the spectrum. The end point is an expected time point. The plurality of dielectric regions are etched to the target etching depth. The etching of the plurality of dielectric regions is stopped at the end point.

  • Patent number: 12159807
    Abstract: In a method of manufacturing a semiconductor device, sacrificial patterns are formed over a hard mask layer disposed over a substrate, sidewall patterns are formed on sidewalls of the sacrificial patterns, the sacrificial patterns are removed, thereby leaving the sidewall patterns as first hard mask patterns, the hard mask layer is patterned by using the first hard mask patters as an etching mask, thereby forming second hard mask patterns, and the substrate is patterned by using the second hard mask patterns as an etching mask, thereby forming fin structures. Each of the first sacrificial patterns has a tapered shape having a top smaller than a bottom.

  • Patent number: 12080587
    Abstract: An apparatus includes a susceptor and a non-reactive gas source. The susceptor has through holes and a wafer support surface. Each through hole includes a lift pin and a lift pin head. The lift pin has a vertical degree of motion in the through hole to lift up or place a wafer on the susceptor. The lift pin head has at least one flow channel structure running from its first surface at least partially exposed to a bottom side of the susceptor through its second surface exposed to a top side of the susceptor wherein the lift pin. The non-reactive gas source is configured to flow a gas to a backside of the wafer through the flow channel structure through the bottom side of the susceptor.

  • Publication number: 20240274668
    Abstract: In a method of manufacturing a semiconductor device including a Fin FET, a fin structure extending in a first direction is formed over a substrate. An isolation insulating layer is formed over the substrate so that an upper portion of the fin structure is exposed from the isolation insulating layer. A gate structure extending in a second direction crossing the first direction is formed over a part of the fin structure. A fin mask layer is formed on sidewalls of a source/drain region of the fin structure. The source/drain region of the fin structure is recessed by a plasma etching process. An epitaxial source/drain structure is formed over the recessed fin structure. In the recessing the source/drain region of the fin structure, the plasma process comprises applying pulsed bias voltage and RF voltage with pulsed power.
