Facility for Avalanche Selenium Technologies (FAST)

Facility for Advanced Selenium Technologies

The Facility for Avalanche Selenium Technologies (FAST) has a wide variety of thin-film fabrication and circuit characterization tools specializing in amorphous selenium research for medical imaging applications.

The FAST lab is equipped with a class 10000 cleanroom which houses our deposition equipment, wet processing station, and device characterization tools.

Deposition Equipment

The FAST lab is equipped with a customized MBraun ProVap physical vapor deposition (PVD) tool for evaporation of thin-film amorphous selenium (a-Se) and its alloys.
Capabilities:

Deposition equipment

  • The PVD system is equipped with three low-temperature organic, one high-temperature organic, and one open-boat thermal sources.
  • A quartz lamp is available inside the vacuum chamber for heating the substrate during deposition.
  • Each source has a dedicated power supply to enable co-deposition.

Wet Processing Station

Our LabCrafters fume hood is dedicated for a wide range of chemical processes.
Capabilities:

Wet Processing Station

  • Organic polymer deposition
  • Laurell W-650Mz spin processor
  • Programmable Torrey Pines Scientific hot plate

Device Characterization

The clean room can be darkened for device characterization and transient photoconductivity measurements.
We are capable to perform both optical and x-ray time-of-flight (TOF) measurements in both low-field and high-field avalanche regions.
Capabilities:

Device Characterization

  • Tektronix 1GHz oscilloscope
  • Tektronix 100 MHz function generator
  • 50 ps pulsed laser source
  • High-Voltage (5 kV) power supply
  • 100 ns pulsed LED source
  • 50 ns pulsed 70 kVp x-ray source
