Abstract:
1. A method of depositing a layer on a semiconductor substrate, comprising: providing a reaction chamber having a first side section and a second side section located opposite one another, the side sections each having facing planar surfaces, wherein at least one of the side sections is heated to a temperature higher than about 200° C.; placing the substrate in the reaction chamber between the first and second side sections; applying two gas streams, in opposing directions, from the first and second side sections to two opposing planar sides of the semiconductor substrate, wherein a spacing between each of the first and second side sections and the semiconductor substrate is about 2 mm or less, wherein facing planar surfaces of the side sections extend completely across the opposing planar sides of the semiconductor substrate, wherein at least one of the gas streams provides first and second reactants in a sequence of alternating, separated pulses for an atomic layer deposition (ALD) process; and maintaining the reaction chamber pressure at about atmospheric pressure while applying the two gas streams.
