  • Patent number: 11508751
    Abstract: A semiconductor device includes an active fin on a substrate, a gate electrode and intersecting the active fin, gate spacer layers on both side walls of the gate electrode, and a source/drain region in a recess region of the active fin at at least one side of the gate electrode. The source/drain region may include a base layer in contact with the active fin, and having an inner end and an outer end opposing each other in the first direction on an inner sidewall of the recess region. The source/drain region may include a first layer on the base layer. The first layer may include germanium (Ge) having a concentration higher than a concentration of germanium (Ge) included in the base layer. The outer end of the base layer may contact the first layer, and may have a shape convex toward outside of the gate electrode on a plane.

  • Publication number: 20220275260
    Abstract: The present disclosure provides a surface protective film which is used in a process of fabricating an encapsulation layer for an organic light-emitting diode, and makes it possible to prevent bubbles from being generated in the protective film or the surface smoothness of the protective film from being degraded, due to solvent volatilization from the protective film. Specifically, the present disclosure provides a surface protective film including an adhesive layer provided on one surface of a substrate layer, wherein the adhesive layer includes a cured product of an adhesive composition including: a urethane-based resin having a photoreactive group at the end or side chain thereof; a monofunctional (meth)acrylate monomer; a crosslinking agent having two or more photoreactive groups at the end thereof; a photoinitiator; and a photoreactive siloxane additive, the adhesive composition being solvent-free.
