摘要
The present invention provides a reaction chamber to monitor a metal ion in solution during the formation of a metal-sulfide layer on a substrate. The reaction chamber houses a solution of an ammonium ion, a metal ion and a buffer. The reaction chamber includes an anion-selective electrode in the solution to monitor the metal ion that measures the metal ion during metal-ammonium complex formation, metal-thiourea complex formation, metal sulfide composition formation, metal sulfide layer formation or a combination thereof.
