Effect of F doping on capacitance-voltage characteristics of SiCOH low-k films metal-insulator-semiconductor structure

Abstract

This paper investigates the capacitance-voltage (C-V) characteristics of F doping SiCOH low dielectric constant films metal-insulator-semiconductor structure. The F doping SiCOH films are deposited by decamethylcyclopentasiloxane (DMCPS) and trifluromethane (CHF3) electron cyclotron resonance plasmas. With the CHF{sub 3}/DMCPS flow rate ratio from 0 to 0.52, the positive excursion of C-V curves and the increase of flat-band voltage V{sub FB} from -6.1 V to 32.2 V are obtained. The excursion of C-V curves and the shift of V{sub FB} are related to the change of defects density and type at the Si/SiCOH interface due to the decrease of Si and O concentrations, and the increase of F concentration. At the CHF{sub 3}/DMCPS flow rate ratio is 0.12, the compensation of F-bonding dangling bond to Si dangling bond leads to a small V{sub FB} of 2.0 V.
