N₂ Blow-Off Dispense

Direct drying gas toward the wafer center to help clear remaining liquid after developing or rinsing. Recipe-controlled timing and adjustable flow let the blow-off step work with the spin sequence.

  • Center-focused gas drying
  • Standard developer or AccuScan™ arm installation
  • Adjustable flow
  • DataStream™ recipe control

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

Select your configuration.

Choose the fixed developer installation or the AccuScan™ arm installation.

Product Information

Overview

N₂ blow-off directs a focused gas jet toward the spinning wafer to assist drying from the center outward. It helps move residual process liquid away from the center as part of the final drying sequence.


Key Capabilities

Adjust the gas flow and coordinate the start time and duration with DataStream™ recipe steps. Match the drying sequence to substrate size, remaining liquid, and spin conditions.


Equipment Compatibility

Choose the standard developer installation or the version mounted on an AccuScan™ developer arm. Both configurations use the dispense control box for automated gas delivery.

Choose the Installation

Select N-1-L for standard N₂ blow-off on an Apogee® developer, or N-1-AS for N₂ blow-off on the AccuScan™ developer arm. These are the two available configurations.


Match the Drying Step to the Process

Confirm the developer model, substrate size, and wet-process sequence. Set gas flow, start time, duration, and spin conditions to suit the remaining liquid and drying requirements. The AccuScan™ configuration requires a compatible arm; the arm and dispense control box are specified separately.

  • N₂ blow-off nozzle, mounted on the developer lid or AccuScan™ arm for the selected configuration
  • Blow-off valve with 6 ft of ⅛″ PTFE (Teflon) tubing attached
  • 6 ft of green poly tubing to pneumatically trigger the valve

The assembly connects to the dispense control box.

Purchased separately: The dispense control box and, for N-1-AS, the AccuScan™ developer arm.
