Organic field-effect transistors (OFETs) are of interest for use in widely area electronic applications. We fabricated a copper phthalocyanine (CuPc) based field-effect transistor with different metal electrode. The CuPc FET made a top-contact type and the substrate temperature was room temperature. The source and drain electrodes were used an Au and Al materials. The CuPc thickness was 40nm, and the channel length was $50{\mu}m$, channel device was width was 3mm. We observed a typical current-voltage (I-V) characteristics in CuPc FET with different electrode materials.

TCAD 시뮬레이션을 이용하여 소스영역으로 오버랩된(overlapped) 게이트를 가진 터널링 전계효과 트랜지스터(Tunnel Field-Effect Transistor; TFET)의 오버랩된 게이트 길이에 따른 터널링 전류 특성을 조사하였다. 터널링은 크게 라인터널링과 포인트 터널링으로 구분되는데, 라인터널링이 포인트터널링보다 subthreshold swing(SS), on-current에서 더 높은 성능을 보인다. 본 논문은 Silicon, Germanium, Si-Ge Hetero TFET구조에서 게이트 길이를 소스영역으로 오버랩될 경우에 포인트 터널링과 라인터널링의 효과를 조사해서 SS와 on-current에 최적합한 구조의 가이드라인을 제시한다.

피드백 전계 효과 트랜지스터(feedback field-effect transistor; FBFET)로 구성된 모놀리식 3차원 정적 랜덤 액세스 메모리(monolithic 3-dimensional static random access memory; M3D-SRAM)에 대해 TCAD(technology computer-aided design) 프로그램을 사용하여 전기적 특성을 조사하였다. FBFET로 구성된 M3D-SRAM(M3D-SRAM-FBFET)는 FDSOI(fully depleted silicon on insulator) 구조의 N형 FBFET와 N형 MOSFET(metal oxide semiconductor field effect transistor)로 이루어져 있으며 각각 하부와 상부에 위치한다. M3D-SRAM-FBFET의 메모리 동작 시, 공급 전압이 1.9 V에서 감소함에 따라 읽기 전류가 낮아졌으며, 공급 전압이 1.6 V 일 때 읽기 전류가 약 10배 감소하였다.

A novel body-tied silicon-on-insulator(SOI) n-channel metal-oxide-semiconductor field-effect transistor with grounded body electrode named GBSOI nMOSFET has been developed by wafer bonding and etch-back technology. It has no floating body effect such as kink phenomena on the drain current curves, single-transistor latch and drain current overshoot inherent in a normal SOI device with floating body. We have characterized the interface trap density, kink phenomena on the drain current ($I_{DS}-V_{DS}$) curves, substrate resistance effect on the $I_{DS}-V_{DS}$ curves, subthreshold current characteristics and single transistor latch of these transistors. We have confirmed that the GBSOI structure is suitable for high-speed and low-voltage VLSI circuits.

The next generation electronics need to not only be smaller but also be more flexible. To meet such demands, electronic devices using two dimensional (2D) atomic crystals have been studied intensely. Especially, graphene which have unprecedented performance fulfillments in versatile research fields leads a parade of 2D atomic crystals. In this talk, I will introduce the electrical characterization and applications of graphene for prominently electrical transistors realization. Even the rising 2D atomic crystals such as hexagonal boron nitride (h-BN), molybdenum disulfide (MoS2) and organic thin film for field effect transistor (FET) toward competent enhancement will be mentioned.

In this paper, two competing mechanisms determining drain current of tunneling field-effect transistors (TFETs) have been investigated such as band-to-band tunneling and drift. Based on the results, the characteristics of TFETs have been discussed in the tunneling-dominant and drift-dominant region.
