Autosamdri®-815B, Series B

  • The Supercritical Autosamdri®-815B, Series B System was developed by Dr. A. J. Tousimis and our team of long-standing associates within the tousimis® SAMDRI design group.

  • Smooth operation and precise control are the Supercritical Autosamdri®-815B´s trademark; wafer holders and inserts are provided that allow anti-stiction processing up to 5 pieces of either 4", 3", 2" wafers or 10mm square die per process run!
  • Process up to 4" wafers
  • Automatic Supercritical Point Dryer
  • Minimal Facility Utility Requirements
  • Made in U.S.A.

  • Microprocessor controller allows for complete automatic processing.*
  • All internal surfaces are inert to CO2 and ultra pure alcohols.*
  • Repeatable operating parameters insuring reproducibility of results.*
  • Integrated temperature controls.*
  • Internal rupture disc built in for safety. *
  • Processes up to 5 x 4" diam. wafers per run; comes with additional HF compatible wafer holders to process 5 x 3", 5 x 2" diameter wafers or 5 x 10mm square die (Tousimis HF compatible Wafer Holders* can be used to transport and process your wafers and die from HF).
  • All electronic components meet CE, UL and/or U.S. Military Specifications.
  • Static pressure control module pre-set for automatic safe pressure stability.
  • 0.08µm internal filtration system delivers clean filtered LCO2 to process chamber. *
  • Under-lit chamber with viewing window facilitates operator chamber status viewing.
  • An efficient adiabatic cooling system*, capable of cooling the chamber from ambient room temperature to near 0°C, in less than 3 minutes and maintains temperature automatically during both FILL and PURGE modes.*
  • LED's instantly indicate process mode at a glance.*
  • Clean room static-free compatible design.
  • For added safety and convenience, the U.S. Patented SOTER™ condenser* quietly captures exhaust and alcohols.
  • Unique chamber inserts* allow variance of chamber I.D. This maximizes efficiency in LCO2 consumption and processing time.
  • Cabinet: 14.25" (36.2cm) Width x 11.75" (29.8cm) Height x 25" (63.5cm) Length
  • System Set-Up Area Required: 42" (107cm) Width x 30" (76cm) Depth
  • Chamber size: 4.50" I.D. x 1.25" depth Chamber volume: 326 ml
  • Temperature gauge range: -30°C to 60°C, Pressure gauge range: 0 to 2,000psi
  • 120V/50-60Hz (Other voltage units also available. Please Inquire)
  • LCO2 flow is controlled through Micro Metering Valves with Vernier handles for easily controlled flow rates.*
  • LCO2 High Pressure braided stainless steel inert Teflon® lined hose. 10ft (~ 3m) long for clean room operation (at a nominal charge, other lengths available upon request).
  • Double T-Filter Assembly (#8785) pre-installed onto the chamber LCO2 supply high-pressure hose. Flows LCO2 twice thru 0.5µm filters with 99.5% particulate retention prior to LCO2 entering Autosamdri®-815B.
  • New SOTER™ Condenser* connects to exhaust hose. Captures all alcohol and deadens exhaust noise.*
  • Static free Exhaust Tubing for all exhaust outlets.
  • Internal stainless and nickel scintered filtration systems incorporated to protect lines, wafers, and valves down to 0.08µm.
  • Spare Chamber O-ring (3), Chamber Lamps (2), and 5A Slo-Blow Fuses (2).
  • 3 Chamber Inserts.* Enables original chamber ID reduction down to smaller chamber ID sizes for a range including: 4", 3", 2", and 1.25" !
  • 4", 3", 2" diameter Wafer Holders and 10mm square Die Holder included. Holders are HF compatible and can hold up to 5 wafers or die each.
