Which issue arises if dopant concentration exceeds the solubility limit during semiconductor fabrication?

💡 Explanation

Second-phase precipitates form because exceeding the solubility limit introduces excess dopant atoms into the crystal lattice. This segregation causes phase separation; rather than increasing dopant effectiveness, unwanted precipitates form, because active dopant concentration remains limited.
