Abstract: A semiconductor device includes: a fin-type active region extending on a substrate in a first direction that is parallel to an upper surface of the substrate; and a source/drain region in a recess region extending into the fin-type active region, wherein the source/drain region includes: a first source/drain material layer; a second source/drain material layer on the first source/drain material layer; and a first dopant diffusion barrier layer on an interface between the first source/drain material layer and the second source/drain material layer.

Abstract: An integrated circuit (IC) device including fin-type active regions parallel to each other on a substrate, the fin-type active regions extending in a first lateral direction, a first nanosheet stack apart from a fin top surface of a first fin-type active region selected from the fin-type active regions, the first nanosheet stack including at least one nanosheet facing the fin top surface of the first fin-type active region, a gate structure surrounding the first nanosheet stack, the gate structure extending in a second lateral direction, a first source/drain region in contact with one sidewall of the first nanosheet stack, and a second source/drain region in contact with another sidewall of the first nanosheet stack , wherein a greatest width of the first source/drain region is less than a greatest width of the second source/drain region in the second lateral direction may be provided.

Abstract: A bottle which allows for an additive to be held in a container within the receptacle of the bottle separately from the contents held in the receptacle of the bottle until the time for mixture desired by the user. The bottle having a receptacle and a mouth leading into the receptacle. The bottle having the container in the receptacle. The container being formed to hold a substance therein and release the substance into the receptacle when the container is pressed with at least a predetermined amount of pressure. The container having a first member and a second member overlapping at least a portion of the first member in a slideable engagement to define a cavity therein. The second member having an opening formed through the surface, which is sufficiently sized to allow for a discharge of a substance contained in the cavity to be discharged therethrough. A cover is formed on the second member closing the opening.

Abstract: There are prepared acrylates and methacrylates of the formula ##STR1## wherein R is hydrogen or methyl, y is 1 to 3, z is 0 to 2, y+z is 3, and wherein A is the unit (I) ##STR2## wherein x is 0 to 4, or the unit (II) ##STR3## with the proviso that when A is unit II, then z is zero. The novel siloxane compounds can be copolymerized with (1) a monoethylenically unsaturated monomer having a polymerizable carbon-to-carbon double bond, and (2) a cross-linking agent having at least two polymerizable, ethylenically unsaturated bonds. The resulting copolymers have high oxygen permeability and proper hydrophilic property. They can be made substantially water non-absorptive. Contact lenses fabricated from such copolymers can, if desired, be worn continuously for long periods of time.
