  • Nano-floating gate memory (NFGM) devices were fabricated by using the low temperature poly-Si thin films crystallized by ELA and the $In_2O_3$ nano-particles embedded in polyimide layers as charge storage. Memory effect due to the charging effects of $In_2O_3$ nano-particles in polyimide layer was observed from the TFT NFGM. The post-annealing in 3% diluted hydrogen $(H_2/N_2)$ ambient improved the retention characteristics of $In_2O_3$ nano-particles embedded poly-Si TFT NFGM by reducing the interfacial states as well as grain boundary trapping states.

  • 본 연구는 비정질실리콘 박막트랜지스터를 비휘발성 메모리소자로 제작함으로써 스위칭 소자로 사용되는 박막 트랜지스터(TFT)의 응용범위를 확대시키고, 비정질 실리콘 사용에 따라 대면적화에 적합하고 아울러 값싼 기판을 사용할 수 있게 한 비정질 실리콘 비휘발성 메모리소자에 관한 것이다. 이와 같은 본 연구는 유리기판과 그 유리기판위에 증착시켜 패터닝한 게이트, 그 게이트를 덮어씌운 제1 절연층, 그 제1 절연층위에 증착시켜 패터닝한 플로우팅 게이트와 그 플로우팅 게이트를 덮어씌운 제2 절연층, 그 제2 절연층위에 비정질실리콘을 증착시킨 액티브층과 그 액티브층위에 n+ 비정질실리콘을 증착시켜 패터닝한 소오스/드레인층 그리고 소오스/드레인층 위에 증착시킨 소오스/드레인층 전극으로 비정질실리콘 박막트랜지스터 비휘발성 메모리소자를 구성한다.

  • Here we report the architecture for a non-volatile n-type memory paper field-effect transistor. The device is built using the hybrid integration of natural cellulose fibers (pine and eucalyptus fibers embedded in an ionic resin), which act simultaneously as substrate and gate dielectric, with amorphous GIZO and IZO oxides as gate and channel layers, respectively. This is complemented by the use of continuous patterned metal layers as source/drain electrodes.

  • 1T-DRAM cell with solid phase (SPC) crystallized poly-Si thin film transistor was fabricated and electrical characteristics were evaluated. The fabricated device showed kink effect by negative back bias. Kink current is due to the floating body effect and it can be used to memory operation. Current difference between "1" state and "0" state was defined and the memory properties can be improved by using gate induced drain leakage (GIDL) current.

  • Reported herein is the architecture for a nonvolatile n-type memory paper field-effect transistor. The device was built via the hybrid integration of natural cellulose fibers (pine and eucalyptus fibers embedded in resin with ionic additives), which act simultaneously as substrate and gate dielectric, using passive and active semiconductors, respectively, as well as amorphous indium zinc and gallium indium zinc oxides for the gate electrode and channel layer, respectively. This was complemented by the use of continuous patterned metal layers as source/drain electrodes.
