Hot-wall cvd
WebApr 30, 2015 · Different reactors configurations (hot-wall, cold-wall, vertical or horizontal) have been proposed by CVD equipment manufacturers. However, hot-wall reactors … WebCVD-based reactors are configured as "Hot Wall" or "Cold Wall" reactors. Controlling the wall temperature allows for the prevention or minimization of vapour condensation on reactor walls. The substrate or the workpiece holders are heated to sufficiently high temperature to optimize the molecular disintegration of gases and vapours and reactive …
