Customer ServiceIn solid source diffusion, the boat carrying the silicon wafers is loaded into the diffusion tube alongside the solid source (e.g. SiP) comprising of a phosphorus and silicon oxide, in the instance of n -type diffusion . The source can either be loaded in the boat with the wafers, or else in a separate platinum carrier.
SVSOL-ALPD® is a solution for the PV industry demand for a high-throughput without compromising the wafer uniformity. The SV-SOL standard “controlled pressure” solution for Phosphorus/Boron difusion is combined with vacuum pump and tight sealing enough to achieve low pressure environment in the process tube during dopant deposition.
Further heating allows the diffusion of the phosphorus atoms into the surface. Gaseous source diffusion is a process where a gaseous dopant source—such as phosphorus oxychloride, phosphorus pentoxide or phosphorus tribromide—is directly introduced with other carrier gases into the diffusion tube.
