Abstract: A semiconductor memory device includes a memory cell structure which includes a channel pattern, a bit line connected to a first portion of the channel pattern, a data storage structure connected to a second portion of the channel pattern, and a word line intersecting the channel pattern between the first portion and the second portion, a substrate which faces the memory cell structure in a first direction, the substrate including a first region and a second region different from each other, a first insulation pattern which defines an active region inside the first region, an active pattern which protrudes from the active region, a gate structure which intersects the active pattern, on the active pattern, a second insulation pattern inside the second region, and a through via which extends in the first direction and penetrates the second insulation pattern.

Abstract: The present invention relates to a fluorescent microscope and a remote control system thereof. The present invention reduces the size of the fluorescent microscope to facilitate transportation and management and be disposed in a narrow place such as the inside of the incubator or the clean bench, etc. and observes the samples through a remote control, thereby making it possible to improve the user convenience.
