8x Scrubber

The C&D Wafer Scrubber is a fully automatic cleaner designed to scrub with brush and/or high pressure arm, rinse, and spin dry substrates.

The brush and high pressure scrub operations are performed at a lower processing position while rinse, blow-off, and final dry operations occur at a middle spindle position in the chamber. This dual level spinning process and the large diameter process enclosure reduce splash and spray onto the substrate and the handling mechanism. Splash back onto the substrate is virtually eliminated.

The Scrubber module is also offered on the P9000 cluster system, and can be paired up with up to 5 Scrubber modules, for extremely high throughput requirements. The P9000 variant also features the use of digital spindle controllers and brushless motors, which allow for highly precise spin speeds, higher spin torque, and programmable brush forces.

Lift-Off System

C&D offers both the P9000 and P8000 Liftoff Systems, which are fully automated and designed for metal lift-off application. The cassette to cassette design offers a reduced overall system footprint. C&D uses a low pressure spray to soak the wafer for a programmed duration – this is followed by a high pressure fine needle spray. The programmed arm sweeps across the wafer to evenly lift off unwanted metal.

The state-of-the-art liftoff module is highly versatile, and can be implemented with many different features to improve efficiency and capability. Up to 5 separate modules can be outfitted into a single P9000 cluster system to maximize throughput capability.

SynchroSpin® Coating System

C&D is proud to introduce the SynchroSpin­® Coating System as one of the customizable modules for our P9000 family of products.

The SynchroSpin­® Coating System is C&D’s state-of-the-art coating system variant that features the simultaneous rotation of both top and bottom of the closed coat bowl for a more controlled environment in which the photoresist is spread across the substrate during the spin coating processes.

The concurrent rotation of both top and bottom of the wafer allows for lower turbulence around the rotating substrate, and results in an improvement in coating planarization and greatly reduced chemical consumption through waste.

The specially designed coater insert is also equipped with an integrated backside automatic wash function.

Used as a standalone coater, or together with other standard coater modules, your next P9000 tool will keep up with exacting requirements in today’s semiconductor industry.

Ultrasonic Coating System

C&D is proud to introduce Ultrasonic Spray Coating to the offerings available on the P9000 family of products. Offered both in standalone or as a drop in module for one of our cluster tools, the C&D ultrasonic coating system is able to more uniformly coat substrates with complex structures that may have high levels of varying topography.

Using a ultrasonic signal generator, the C&D coating system will mist the desired chemistries using parameters finely calibrated to the specific physical properties of the photoresist. Compressed nitrogen is used not as a propellant of the solution, but solely as a shaping spray to direct the photoresist atomized by the ultrasonic frequencies. This results in a much more uniform coating for complex geometries and topographic substrates, and requires a greatly reduced amount photoresist than traditional checmical coating methods.
