Abstract: A semiconductor device is provided. The semiconductor device includes an active region, a first source/drain region disposed on the active region, a first contact on the first source/drain region, a second source/drain region spaced apart from the first source/drain region and disposed on the active region, a second contact on the second source/drain region and a first gate electrode disposed on the active region. The first gate electrode includes a first ring portion, which surrounds the first contact, but the second contact extends outside the first ring portion.

Abstract: A semiconductor memory device includes: a substrate including a first region and a second region, the first region includes a peripheral circuit and a first active region (FAR), and the second region includes memory cell blocks. The FAR includes a FAR first extension extending in a first direction, a FAR second extension extending in a second direction, and a FAR third extension extending in a third direction. The FAR first extension, the FAR second extension, and the FAR third extension form an angle greater than 90 degrees relative to one another. The device includes a first pass transistor circuit configured to transmit driving signals, and the first pass transistor circuit includes a FAR first gate structure on the FAR first extension, a FAR second gate structure on the FAR second extension, a FAR third gate structure on the FAR third extension, and a first shared source/drain.

Abstract: The present invention relates to a photocurable hemostatic composition and, specifically, to a photocurable liquid hemostatic composition containing a hyaluronic acid-based photocrosslinkable compound and a photoinitiator as active ingredients, and to a hemostatic agent of a film or sponge formulation freeze-dried from the composition, wherein, by increasing the degree of substitution of a photocrosslinkable functional group, the composition can quickly form a gel or a film adhesive layer within a few seconds during light radiation, and the resulting gel remains in a body more stably for a long time, thus enhancing hemostasis and tissue regeneration effects.

Abstract: A mold for producing a hydrogel support for a 3-dimensional (3D) cell culture, includes: an upper mold comprising a base and a plurality of upper unit molds protruding downward from the base to form accommodating portions of a female type corresponding to shapes of hydrogel supports, having through holes at bottoms thereof, and patterned at a lower portion of the base; a lower mold where a plurality of lower unit molds are patterned, the plurality of lower unit molds formed in a female type to respectively accommodate the plurality of upper unit molds protruding downward and having sealed lower portions; and an ejecting unit for separating, from the accommodating portions of the plurality of upper unit molds, the hydrogel supports that are coagulated after being inserted into the through holes respectively formed in the plurality of upper unit molds.

Abstract: Disclosed is an apparatus for manufacturing a microneedle patch, including: a silicon mold mounted on an upper surface to mold a material for the microneedle patch; a carrier of which the silicon mold is mounted on an inside of the upper surface; an upper block which is assembled with the carrier to form a chamber in which the material and the silicon mold are accommodated; an air cylinder which is connected to the upper surface of the upper block to transmit power so that the upper block descends to be assembled with the carrier and ascends to be separated from the carrier; and a pressing portion which is connected to a side surface of the upper block so as to press the chamber or ventilate the chamber while the upper block and the carrier are assembled with each other.
