  • Publication number: 20230006105
    Abstract: A micro light-emitting device includes an epitaxial structure, a first electrode, a second electrode and a conductive layer. The epitaxial structure includes a first-type semiconductor layer, a light-emitting layer, and a second-type semiconductor layer. The first-type semiconductor layer includes a first portion and a second portion. A bottom area of the first portion is smaller than a top area of the second portion. A thickness of the second portion is greater than 10% of a thickness of the first-type semiconductor layer. The first electrode is disposed on the epitaxial structure and located on the first portion of the first-type semiconductor layer. The second electrode is disposed on the epitaxial structure. The conductive layer is disposed between the first electrode and the first portion, wherein an orthographic projection area of the conductive layer on the first portion is greater than or equal to 90% of an area of the first portion.

  • Publication number: 20220293503
    Abstract: In some implementations, one or more semiconductor processing tools may form a metal cap on a metal gate. The one or more semiconductor processing tools may form one or more dielectric layers on the metal cap. The one or more semiconductor processing tools may form a recess to the metal cap within the one or more dielectric layers. The one or more semiconductor processing tools may perform a bottom-up deposition of metal material on the metal cap to form a metal plug within the recess and directly on the metal cap.
