Abstract: We report on the investigation of electrical properties of polycrystalline 3C-SiC thin films deposited on oxidized Si by low pressure chemical vapor deposition (LPCVD) to obtain bi-layer structures [Si(100)/SiO2/poly 3C-SiC] for pressure sensors and micro-electromechanical system (MEMS) applications. Polycrystalline 3C-SiC films have been preliminary characterized in their compositional, structural, morphological and electrical properties. Moreover, metal contact definition has been carefully optimized by transmission line method (TLM) analyses performed at different temperatures. We focuses the attention on the evaluation of the bulk resistivity (ρ), the specific contact resistivity (ρc) and their behavior dependence on the temperature because these are the characteristics of major importance for the fabrication of pressure sensors or MEMS.

Abstract: This paper reports on the defects created in a 6H-SiC p-type substrate by a process of ion implantation and a quite low temperature annealing (1300 °C), suitable for the realization of the source/drain regions of a MOSFET because it does not give rise to step bunching phenomena. Current voltage measurements showed the presence of a group of diodes featured by excess current. The effects of defects under the implanted layer on the transport properties of the diodes were investigated by DLTS: four hole traps were detected in all the measured diodes; besides, a broadened peak around 550 K was detected in the diodes that show excess current.
