substrate 10 from a first end to a second end of thesubstrate 10. We flow liquids (e.g., chemicals) thru the first manifold (blade) 24 and firstliquid nozzles 50 onto thesubstrate 10. As the second manifold passes over the substrate, the second manifold removes the chemicals and other contaminants from the substrate with a vacuum through the second manifold (blade) 28 andsecond drying nozzles 60. Preferably both the first and second blades pass over the entire substrate surface. - In the first (forward) pass/step (and all other passes or steps), either the substrate moves and the blades are stationary, or the manifolds are stationary and the substrate moves. The wafer can be moved on the transportation means 20. Alternatively, both the substrate and the manifolds can move. When we state that the manifold moves relative to the wafer or wafer transporter, it is understood that either the manifold or the wafer/wafer transporter moves or both.
- B. Optional Back-Up Step
- In an optional (back-up) step, we pass the first and
second blades 24 28 over the substrate from the second end to the first end of thesubstrate 10. - C. Second Pass/Step—Rinse/Dry Step
- In a second (forward) pass step, we pass the first and
second blades 24 28 over the substrate from a first end to a second end. We flow second liquid (e.g., water) from the liquid source through the first manifold (blade) 24 and firstliquid nozzles 50 onto thesubstrate 10. We remove the liquid (expelled by the first nozzles) from the substrate by using a vacuum or a gas blown through the second manifold (blade) 28 andsecond nozzles 60. - The second example device embodiment is a wafer cleaning tool that has a first wafer scrubber manifold with capillary jet nozzles on the bottom.
-
FIG. 2A shows an apparatus for cleaning asubstrate 210. Thesubstrate chuck 216 supports asubstrate 210. A rotation means 218 rotates thesubstrate 210. - The rotation means can comprise the following. A
substrate chuck 216 can be vacuum activated and is mounted on arotatable spindle 217. Thespindle 217 can be operatively connected to an electric motor. A speed controller is operatively connected to the motor for rotating the spindle at a selected variable speed. - A. Wafer Scrubber Manifold has CJ Nozzles
- A tubular 222 or circular 223 manifold (blade) preferably has a central passageway(s) in communication with spaced-apart capillary jet (CJ) nozzles 226 on the bottom of the
blade 222. The manifold/blade can be placed just above the wafer/substrate. - B. Capillary Jet Nozzles
-
FIG. 2B shows a view of the bottom of the CJ nozzles 226 in thewafer scrubber manifold 222. -
FIG. 2B shows a blade type manifold design. -
FIG. 2D shows a side view of around type manifold 223.FIG. 2D is a side view of thecircular manifold 223 shown inFIG. 2C .FIG. 2D shows theboundary distance 227. -
FIG. 2C shows a bottom view of around type manifold 223 design. This round or circular manifold/blade 223 can be placed just above the wafer/substrate. - Very dense capillary jet (CJ) nozzles 226 on the bottom of the shower head (manifold) 222 are spaced as densely as possible to cover the entire bottom surface or at least the area corresponding to the substrate to be cleaned.
- The CJ nozzles preferably have an opening with a size less than 0.1 micron or about equal to 0.1 micron. The idea is that the jet coming out of a 0.1 micron opening is small/“sharp” enough to dislodge similar sized particles on each area of the surface of the substrate.
- The pressure of the liquid should be strong enough to dislodge particle/residues.
- The (manifold)
shower head 222 223 is preferably kept as close as possible to the wafer (close to the boundary layer) for maximum effect. - The tubular
capillary jet device 222 is configured to orient the capillary nozzles to direct the jet stream of liquid to the surface of the substrate at an angle of incidence with respect to the surface of the wafer of not more than about 10 degrees. - The capillary jet nozzles preferably point in an approximately vertical direction (within +/− 10 degrees of vertical) to the surface of the substrate.
- There are preferably at least 1 or more rows of CJ nozzles 226. The nozzles can also have other orientations. The exact number or row and nozzles should be optimized for the particular process.
- For the round (circular or cylindrical) manifold in
FIG. 2C , theround manifold 223 should be slightly bigger (for better coverage) than thewafer 10 size when it is placed directly over the wafer surface. The round manifold has a bottom shape that can be slightly larger than the wafer to be cleaned. The round manifold has a bottom shape that can completely cover the wafer to be cleaned. - C. Arm
- An arm is connected (directly or indirectly) to or attached to the tubular manifold. Indirectly connected means that another object(s) can be connected to the manifold and to the arm. For example, referring to
FIG. 2A ,arm 230 is connected to or attached to thetubular manifold 222. Theretractable arm 230 preferably has a center passageway connected to a center passageway in the tubularcapillary jet device 222 connected to thecapillary jet nozzles 226. Theretractable arm 230 can be attached to a retracting means to move the retractable arm back and forth. The retracting means can be a mechanical assembly. - The arm can have arm supports 231.
- In operation the manifold can be moved back and forth across the wafer or the wafer is moved relative to the manifold.
- D. Liquid Source
- The
liquid source 236 is connected to the manifold. The liquid source can supply water or a chemical and, most preferably, supplies water. - The
liquid source 236 and the capillary jet nozzles are adapted to inject the water jet steam. - A liquid (e.g., water)
source 236 is connected to aretractable arm 230 that communicates with the capillary jet nozzles to produce a jet stream ofliquid 240. - A retraction means can move the manifold 222 over the substrate in a linear direction.
- E. Retraction Means
- The retraction means that moves the manifold to pass over the wafer can be comprised of a motor mechanism. The retraction means can be connected to the
arm 230. - In a second example method embodiment, the 2nd example device embodiment (
FIGS. 2A , 2B, 2C and 2D) is used in a method to clean and dry substrates. - The example method can be described as follows.
- We provide the equipment described above for the second device embodiment.
- A. Rotate the Substrate Upon the Substrate Chuck
- We rotate the
substrate 210 upon thesubstrate chuck 216. - B. Direct a Stream of Liquid from the Capillary Jet Nozzles onto the Surface of the Substrate
- We direct a stream of liquid 240 from the
capillary jet nozzles 226 onto the surface of thesubstrate 210. Water or a liquid from theliquid source 236 passes through thearm 230,manifold 222 andCJ nozzles 226 onto the substrate. - C. Manifold Across the Entire Substrate
- We move the
retractable arm 230 and tubularcapillary jet device 222 across theentire substrate 210 in a first direction and back in an opposite direction. - The stream of
fluid 240 from thecapillary jet nozzles 226 has a pressure on the substrate surface. The stream cleans the surface of the substrate. - The method can also comprise withdrawing the manifold so the manifold is not over the substrate. Then we can spin the substrate using the substrate chuck to dry the substrate.
- D. Non-Limiting Example Embodiments
- Given the variety of embodiments of the present invention just described, the above description and illustrations should not be taken as limiting the scope of the present invention defined by the claims.
- While the invention has been particularly shown and described with reference to the preferred embodiments thereof, it will be understood by those skilled in the art that various changes in form and details may be made without departing from the spirit and scope of the invention. It is intended to cover various modifications and similar arrangements and procedures, and the scope of the appended claims, therefore, should be accorded the broadest interpretation so as to encompass all such modifications and similar arrangements and procedures.
