摘要:
The present invention relates to a method for providing a copper seed layer on top of a barrier layer wherein said seed layer is deposited onto said barrier layer from an aqueous electroless copper plating bath comprising a water-soluble source for Cu(II) ions, a reducing agent for Cu(II) ions, at least one complexing agent for Cu(II) ions and at least one source for hydroxide ions selected from the group consisting of RbOH, CsOH and mixtures thereof. The resulting copper seed layer has a homogeneous thickness distribution and a smooth outer surface which are both desired properties.
摘要:
In a processing system for electroplating semiconductor wafers and similar substrates, the contact ring of the electroplating processor is removed from the rotor of the processor and replaced with a previously deplated contact ring. This allows the contact ring to be deplated in ring service module of the system, while the processor continues to operate. Wafer throughput is improved. The contact ring may be attached to a chuck for moving the contact ring between the processors and the ring service module, with the chuck quickly attachable and releasable to the rotor.
摘要:
A method for electroplating a wafer detects plating bath failure based on a voltage change. The method is useful in plating wafers having TSV features. Voltage of each anode of a plating processor may be monitored. An abrupt drop in voltage signals a bath failure resulting from conversion of an accelerator such as SPS to it's by products MPS. Bath failure is delayed or avoided by current pulsing or current ramping. An improved plating bath has a catholyte with a very low acid concentration.
