Abstract: Disclosed is a field effect transistor including an insulating film disposed between a source/drain region and a substrate. Since the insulating film prevents current leakage under a channel, it is not necessary to form a punch-through stopper. Further disclosed is a method of forming a field effect transistor.

Abstract: A touch sensor-antenna module according to exemplary embodiments of the present invention includes a substrate layer, a touch sensor electrode layer disposed on a central portion of an upper surface of the substrate layer, and antenna patterns disposed on a peripheral portion of the upper surface of the substrate layer at the same level as that of the touch sensor electrode layer. Mutual interference between the touch sensor electrode layer and the antenna pattern may be reduced to improve signal reliability and process efficiency.

Abstract: Provided is a system and method for estimating an end-to-end delay between blockchain nodes in peer-to-peer (P2P) networks. The system includes a coordinate system construction unit configured to designate an origin node and anchor nodes among participating nodes having a distributed ledger of P2P networks, construct a first coordinate system of a predetermined dimension by exchanging control messages between the origin node and the anchor nodes and the participating nodes, and construct a second coordinate system of another predetermined dimension and a dimension determination unit configured to determine a dimension to be applied to the current P2P networks by comparing dimension-specific delays or control message overheads of the first coordinate system and the second coordinate system.

Abstract: A two-terminal atom-based switching device having a fast operating speed and high durability and a manufacturing method thereof are disclosed. It is possible to reduce a forming voltage during positive voltage forming by forming an oxygen vacancy percolation path through negative voltage forming, which is first forming, and forming high binding energy and low formation energy between oxygen vacancies and metal ions implanted through positive voltage forming which is second forming after the negative voltage forming. Further, since a significant amount of metal ions implanted into the insulating layer through negative voltage application switching after the positive voltage forming is removed, the volatility of the two-terminal atom-based switching device may be improved, and a stuck-on failure phenomenon in the durability may be prevented.
