Abstract
Strain-free mounting and uniform heating of deposition substrates are achieved by coating the backside of the substrate such as a GaAs substrate with a reflective layer. A reflective environment formed, for example, by tantalum foils allows reflections between the reflective surface of the substrate and the reflective surface of the environment. These multiple reflections, in turn, produce uniform heating of the substrate.
