Abstract:
A post-CMP (Chemical-Mechanical Polishing) semiconductor substrate cleaning apparatus including a plurality of stations, comprising:a first QDR (Quick Dump Rinse) DI water bath for receiving a cassette of semiconductor substrates from a previous CMP processing station, for keeping said semiconductor substrates submerged in DI water following CMP and before transmission to a next processing station and for performing at least one rinsing and dumping operation on said semiconductor substrates in flowing DI water;a loader mechanism for transferring said semiconductor substrates from the cassette to a single substrate processing chuck;a chuck clean bath for cleaning the single substrate processing chuck;a chemical bath for receiving semiconductor substrates;a second QDR (Quick Dump Rinse) DI water bath for receiving semiconductor substrates from said chemical bath and for performing at least one rinsing and dumping operation on said semiconductor substrates in flowing DI water;a semiconductor substrate dryer; andan unloader mechanisim for transferring said semiconductor substrates from the single substrate processing chuck to a cassette.
