Intelligent Semiconductor Device Laboratory (ISDL)

Welcome to the ISDL in Pukyong National University (PKNU) !!

Research Introduction (연구 소개)

뉴로모픽 시스템은 생물학적 신경계를 모방하여 기존 폰 노이만 구조 기반 컴퓨팅 시스템보다 높은 연산 효율을 구현할 수 있는 차세대 기술로 주목받고 있습니다. 우리 연구실은 뉴로모픽 시스템의 핵심 구성 요소인 시냅틱 소자(synaptic device) 기술을 연구하고 있습니다.
우리 연구실은 시냅틱 박막 트랜지스터(Synaptic Thin-Film Transistor, Syn-TFT) 및 시냅틱 패스 트랜지스터(Synaptic Pass-Transistor, SPT) 구조를 기반으로 인공지능 연산에 적합한 뉴로모픽 반도체 소자를 개발하고 있습니다. 또한, 차세대 지능형 반도체 소자인 멤리스터(Memristor), 임계 스위칭 소자(Threshold Switching Device, TS Device) 등 다양한 신개념 소자의 설계, 공정 및 특성 연구를 수행하고 있습니다.
이를 통해 높은 에너지 효율과 연산 성능을 갖는 차세대 인공지능 반도체 및 뉴로모픽 시스템 구현을 목표로 합니다.
