    Abstract: Methods and apparatus for determining whether a substrate includes an unacceptably high amount of oxide on its surface are described. The substrate is typically a substrate that is to be electroplated. The determination may be made directly in an electroplating apparatus, during an initial portion of an electroplating process. The determination may involve immersing the substrate in electrolyte with a particular applied voltage or applied current provided during or soon after immersion, and recording a current response or voltage response over this same timeframe. The applied current or applied voltage may be zero or non-zero. By comparing the current response or voltage response to a threshold current, threshold voltage, or threshold time, it can be determined whether the substrate included an unacceptably high amount of oxide on its surface. The threshold current, threshold voltage, and/or threshold time may be selected based on a calibration procedure.

    Abstract: A system for controlling the operation of apparatus for electroplating semiconductor substrates includes operating in a high mode of operation in which an off-the-shelf power supply provides current or voltage that is directly used to produce the channel control signal and in a low mode of operation in which the off-the-shelf power supply biases a circuit that provides a current or voltage to produce the channel control signal.

    Abstract: The invention relates to an aqueous plating bath composition and a method for depositing a palladium layer by electroless plating onto a substrate. The aqueous plating bath composition according to the invention comprises a source for palladium ions, a reducing agent for palladium ions and an unsaturated compound. The aqueous plating bath composition according to the invention has an improved stability against undesired decomposition due to the unsaturated compounds while keeping the deposition rate for palladium at the desired satisfying value. The aqueous plating bath composition has also a prolonged life time. The unsaturated compounds of the invention allow for adjusting the deposition rate to a satisfying range over the bath life time and for electrolessly depositing palladium layers at lower temperatures.

    Abstract: An electroplating system includes a processor has a vessel having a first or upper compartment and a second or lower compartment containing catholyte and anolyte, respectively, with an processor anionic membrane between them. An inert anode is located in the second compartment. A replenisher is connected to the vessel via catholyte return and supply lines and anolyte return and supply lines, to circulate catholyte and anolyte through compartments in the replenisher separated by a replenisher anionic membrane. The replenisher adds metal ions into the catholyte by moving ions from a bulk metal source, and moves anions from the anolyte through the anionic membrane and into the catholyte. Concentrations or metal ions and anions in the catholyte and the anolyte remain balanced.
