Abstract
An apparatus for chemical deposition of layers of different materials with pulsed automated dosing of a hot gas phase of volatile metal-organic compounds (precursors) admitted into a reaction chamber is described. The apparatus has three channels for dosing the gas precursor phase and three channels for dosing reacting gases. As an example, a technique for depositing HfO2 films on a (100)Si substrate is presented, and the deposited films are analyzed. It is shown, that this apparatus can be used to deposit layers on complex 3D systems with a large aspect ratio using an example of the deposition of HfO2 layers on the inner surfaces of channels of a microchannel plate.
