Claim Text:
1. A hydride vapor phase epitaxy (HVPE) crystal growth reactor apparatus that provides for the growth of group III-nitride materials comprising: a crystal growth chamber that includes an outer reactor tube made of quartz; a seed holder supported inside the outer reactor tube, the seed holder including a top surface that defines a cavity in which a seed is positioned; a protective flexible material liner applied over the top surface of the seed holder, the protective flexible material liner defining a window that generally corresponds to a shape and size of the cavity defined by the top surface of the seed holder; a storage roll from which the protective flexible material liner or a portion thereof is unrolled; and a take-up roll onto which the protective flexible material liner or a portion thereof is rolled after a growth of group III-nitride material in which the protective flexible material liner collected a parasitic deposit of the group III-nitride material.
