 In this study, we fabricate Si/SiGe core-shell Junctionless accumulation mode (JAM)FinFET devices through a rapid and novel process with four main steps, i.e. e-beam lithography definition, sputter deposition, alloy combination annealing, and chemical solution etching. The height of Si core is 30 nm and the thickness of Si/SiGe core-shell is about 2 nm. After finishing the fabrication of devices, we widely studied the electrical characteristics of poly Si/SiGe core-shell JAM FinFET transistors from a view of different Lg and Wch. A poly-Si/SiGe core -shell JAMFETs was successfully demonstrated and it also exhibits  a superior subthreshold swing of 81mV/dec and high on/off ratio > 105 when annealing for 1hr at 600°C. The thermal diffusion process condition for this study are 1hr at 600°C and 6hr at 700°C for comparison. The annealing condition at 700oC for 6 hours shows undesired electrical characteristics against the other. Results suggests that from over thermal budget causes a plenty of Ge to precipitate against to form SiGe thin film. Annealing JAMFETs at low temperature shows outstanding Subthreshold swing and better swing condition when compared to its counterpart i.e. at higher temperature. This new process can still fabricate a comparable performance to classical planar FinFET in driving current.

New Generation

As a new-generation green composite, core-shell structure nature fibers/ polymer composites (NFPC) has been recently developed and used to enhance performance characteristics of composites. The shell layer, made of thermopolymers unfilled or filled with minerals or nature fibers and other additives, plays a critical role in enhancing overall composite properties. The co-extrusion technology for different structural and material combinations are, however, needed to achieve desired processing. In this paper, co-extrusion technology and core-shell structure NFPC have been discussed by systematically studying the effect of structure on properties of NFPC. The result of this paper can help provide a fundamental base for developing new functional applications of core-shell structure NFPCs.
