For Preventing pattern collapse

Compact Supercritical Dryer

A pattern collapses when liquid surrounding the pattern in various fabrication processes dries up.
Supercritical drying can prevent the pattern collapse.

Benefits / Features

Novel supercritical process

  • The new solvent; non-flammable, and low-toxic fluorocarbon liquid (HFE), which is different from conventional high-pressure CO2 gas, is used as a supercritical material.
  • Critical pressure of HFE is about one-third of that of CO2. It enables the downsizing of system.
  • High zeta potential of HFE avoids particle adhesion.

Simple operation

  • Process is started by only pushing a start button after filling the chamber with HFE.
  • No additional high-pressure gas cylinder is necessary.

Space saving

  • The footprint is less than 1m2 , e.g., for laboratory use.

Easy Customization

  • Simple device configuration enables customers to design the chamber with a various size.

Safety devices

  • High safety is maintained by a door lock system, an overheat protector, safety valves for overpressure, etc.
