Methods for forming contact plugs with reduced corrosion |
| abstract |
A method includes forming an ILD to cover a gate stack of a transistor. The ILD and the gate stack are parts of a wafer. The ILD is etched to form a contact opening, and a source/drain region of the transistor or a gate electrode in the gate stack is exposed through the contact opening. A conductive capping layer is formed to extend into the contact opening. A metal-containing material is plated on the conductive capping layer in a plating solution using electrochemical plating. The metal-containing material has a portion filling the contact opening. The plating solution has a sulfur content lower than about 100 ppm. A planarization is performed on the wafer to remove excess portions of the metal-containing material. A remaining portion of the metal-containing material and a remaining portion of the conductive capping layer in combination form a contact plug. |
