Abstract

In this paper we report the role of the a-Si:H on the electrical behaviour of Metal/ a-Si:H / Metal memory devices. We have investigated layers deposited at 250°C by the glow discharge method with various doping concentrations, from undoped up to 104vppm of either diborane or phosphine in silane. We have found that the a-Si:H layer affects the initial forming process and the subsequent OFF state resistance. The hydrogen contents of the films have been measured and are found to correlate, for the p-type samples, with the forming voltage.
