Charge trapping is a key factor determining the performance of charge trap flash memory devices. Nowadays, organic-inorganic hybrid materials have drawn much attention for the charge trap materials due to merging their advantages; functionality and electrical/thermal stabilities from organic and inorganic parts, respectively. A new kind of organic-inorganic hybrid polymer, silole-neopentasilane (SNPS), was invented and synthesized for realization of its charge trap properties. Organic portions consisting of (tetraphenyl)silole rings were responsible for negative charge (electron) trapping, while the Si-O-Si inorganic linkages provided the intrachain energy barrier for controlling electron transport. The SNPS was synthesized by solution process from dihydroxy (tetraphenyl)silole (DS) and dodecachloroneopentasilane (DCPS) with a catalyst of triethylamine. The molecular structure and weight of the SNPS were analyzed by 1H-nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), and gel permeation chromatography (GPC). Then, the SNPS thin films were fabricated by spin-coating onto Si-wafers. The electron trapping of the SNPS thin films was confirmed from the positive flat band shift (ΔVFB) in the capacitance-voltage (C-V) measurements performed within the metal-insulator-semiconductor (MIS) device structure.
