Abstract: The partial deposit films on p-silicon wafers were formed from three kinds of plating solution: chloro-platinic acid, potassium tetranitroplatinate and diammine platinium dinitrate under Nd: YAG laser irradiation.The compositions and properties of the depositswere investigated by AES, SEM and XPS techniques.The Pt deposits have ohmic contactwith p-type silicon.

Key words: platinium plating, laser induced deposition, p-silicon
