NanoFab Tool: Tousimis Autosamdri-815 Series B

      The Tousimis Supercritical Autosamdri-815 Series B critical point dryer utilizes liquid carbon dioxide (LCO2) to dry substrates in a controlled manner in order to release suspended and floating structures on microelectromechanical systems. The critical point dryer uses high temperature and pressure to transition from liquid to gas without crossing a phase boundary, thereby removing the surface tension between the sample and the surrounding liquid. It can accommodate substrates ranging from 25 mm diameter wafers down to small pieces.

Specifications/Capabilities
      
                          Small sample chamber allows quick drying time.
	Chamber illumination with viewing window to monitor processes.
	Automatic processing for repeatable results.
	High pressure LCO2 used as drying fluid.
              Usage Information
        
Supported Sample Sizes
                                Maximum wafer diameter: 25 mm (1 in).
	Small pieces supported: Yes.
              Typical Applications
      
                          Microelectromechanical systems (MEMS).
	Drying suspended and floating structures.
	Nondestructive drying of membranes.Back to the NanoFab Equipment List
