A substrate, a cathode electrode formed on the substrate, a gate insulating layer which is formed on the cathode electrode and has a through hole corresponding to part of the cathode electrode, a gate electrode which has a gate hole corresponding to the through hole and is formed on the gate insulating layer, and an emitter formed on the gate electrode exposed to the bottom of the through hole. In the NAND type flash memory device, a memory cell array is divided into a plurality of blocks, and a data inputoutput path is selectively controlled by a predetermined data rate option and introduced addresses to perform data inputoutput operations at a \xd78 or \xd716 speed in one chip. In one embodiment the axially movable member has a central post which is slidably guided by a tripod at the outer end of the axial passage. Based on the present disclosure, the network could reduce the paging overhead by require the MTC device to acquire the EAB-SIB only when it needs the EAB information. In this regard, according to one example embodiment, a microball delivery assembly includes a mask with at least two microball holder to hold at least two different sizes of microball that may correspond with at least two different-sized openings on a substrate, to provide simultaneous delivery of different-sized microballs upon a substrate. At least one electrical connector is configured to connect one end of a first LED PCB to an end of a second said LED PCB such that the first and second LED PCBs are electrically connected end-to-end.
