摘要:
Embodiments of the invention provide a cluster tool configured to deposit a material onto a substrate surface by using one or more electroless, electrochemical plating, CVD and/or ALD processing chambers. In one aspect, a ruthenium-containing catalytic layer is formed. Embodiments of the invention provide a hybrid deposition system configured to deposit a seed layer on a substrate with an electroless process and to subsequently fill interconnect features on the substrate with an ECP cell. Other aspects provide an electroless deposition system configured to deposit a seed layer on a substrate, fill interconnect features on a substrate, or sequentially deposit both a seed layer and fill interconnect features on the substrate. One embodiment provides an electroless deposition system configured to form a capping layer over substrate interconnects. The system includes a vapor dryer for pre- and post-deposition cleaning of substrates as well as a brush box chamber for post-deposition cleaning.

A lifting mechanism includes a plurality of lift pins which may be driven separately and independently upward to engage an alignment surface of the chamber using ambient atmospheric pressure as the chamber is evacuated by a pump. In the illustrated embodiment, each lift pin includes a piston which is exposed to the internal chamber pressure on one side of the piston, and is exposed to the external ambient pressure on the other side of the piston. As the pump evacuates the chamber, the internal chamber pressure decreases, causing each lift pin piston to drive the associated lift pin upward. Once all the lift pins have securely engaged the alignment surface, the lift pins may be clamped to a linking mechanism to permit a motor to actuate the lift pins during processing operations.

Embodiments of the invention generally provide a fluid processing chamber, sensors and a controller and method for using the same. The fluid processing chamber includes an inlet region, a processing region and an outlet region. The inlet region generally contains one or more sensors and an external controller to monitor the characteristics of the processing fluid at the inlet to the processing region. The outlet region generally contains one or more sensors and an external controller to monitor the characteristics of the processing fluid leaving the processing region of the chamber. In one embodiment the processing region contains one or more sensors and an external controller to monitor the characteristics of the processing fluid in the processing region. The sensors may include, for example, an ORP probe, a temperature sensor, a conductivity sensor, a dissolved hydrogen sensor, a dissolved oxygen sensor, and a pH sensor. The fluid processing chamber is generally useful for all process steps done to deposit an electroless deposited film on a substrate including, for example, all pre-clean process steps (substrate preparation steps), all electroless activation process steps, all electroless deposition steps, and all post electroless deposition cleaning steps.

摘要:
A plasma applicator having a tube that is surrounded by a cooling jacket such that a volume is defined proximate the tube. The volume is filled with a thermal transfer medium to couple heat from the tube to the cooling jacket. The cooling jacket contains an aperture through which energy is transmitted to a process gas contained in the tube. As such, the process gas is infused with energy and a plasma is formed in the tube.
