AccuScan™ Stream Dispense

AccuScan™ is a major capability upgrade for your Apogee® spin coater. Bring radial stream dispensing and high-precision edge bead removal into one automated coating sequence, with control over where material lands, how the nozzle moves, and when each dispense takes place.

  • Radial stream dispense from the center toward the wafer edge
  • High-precision EBR with programmable edge positioning
  • 0.1 mm position resolution and ±50 µm positioning accuracy
  • Recipe-controlled arm speeds from 0–50 mm/s
  • Up to three dispense nozzles for coating and edge-treatment steps
  • Off-wafer pre-dispense and a drip-free park position

A major upgrade in process control

Requires a four-position dispense control box, sold separately. One box supports up to four dispenses. Need more than four dispenses? Add four-position dispense control boxes to expand your system.

Product Information

Full Control Over Your Dispense Method

AccuScan™ gives you programmable control over how material is dispensed and where it lands on the wafer. Use the arm in five ways, with nozzle position and motion defined around your process:

  • Radial dispense: Move the stream from the center toward the wafer edge while dispensing, with control over the start position, end position, and arm speed.
  • Precision edge bead removal: Position the solvent stream accurately at the wafer perimeter to create the desired edge exclusion.
  • Off-wafer pre-dispense: Dispense away from the wafer before moving into position for the coating step.
  • Center dispense: Move the nozzle to the wafer center for a conventional fixed-position dispense, then retract the arm.
  • Annular coating: Dispense at an offset from the center to coat a ring-shaped area while leaving the wafer center uncoated.

Recipe Control and Integrated Design

DataStream™ coordinates arm movement and dispense selection within the process sequence. Up to three nozzles provide options for multiple coating materials or a dedicated edge-treatment fluid. Off-wafer pre-dispense clears the nozzle before on-wafer delivery, and the arm parks away from the wafer between processes.

Cleanroom-compatible construction combines an acetal arm with a hub-less lid design. AccuScan™ operates without an external power supply.

Tool and Process Requirements

Choose the AccuScan™ option for your Apogee® 200 or Apogee® 450 spin coater, then define your wafer size, coating material, viscosity, and dispense sequence. For radial dispensing, define the intended start and end positions. For EBR, include the solvent and desired edge exclusion so nozzle placement and delivery can be configured around the application.

Dispense Hardware and Material Supply

Cartridge dispense, pressure can dispense, and dispense pumps provide different approaches to material storage and delivery. Choose the supply around batch size, refill frequency, chemistry, and viscosity, then pair it with the appropriate tubing, valve, and tip.

For pressure can supply, choose a 1, 2, 3, 5, or 10 gallon reservoir and standard stainless steel or PFA-coated construction to suit the material, usage, and refill frequency.

X-Pro pressure can storage: 1- and 2-gallon pressure cans fit inside the X-Pro in the designated storage area. Pressure cans larger than 2 gallons must be located outside the X-Pro.

The AccuScan™ arm is supplied pre-mounted with nozzles and assorted tips. Dispense systems and the control box are required and sold separately. Review nozzle selection, radial motion, fixed dispense positions, pre-dispense, and edge-treatment steps as one sequence so the configuration supports the complete process.
