The UNT Nanofabrication Cleanroom has a wide selection of processing tools, including
dual e-Beam, thermal evaporation and sputtering systems for thin film development,
and two RIE systems for metal and dielectric material etching of MEMS structures.
Sub-micron features are defined with a JEOL JSM-7001F SEM/EBL system with 3nm beam
resolution and a Heidelberg DWL66fs maskless laser writer for photomask pattern writing.
Four wet benches, HMDS 15 oven and spin coater hood with tabletop spin coater (Laurell
WS-650Mz) are used for lithography process. For characterization analysis, the cleanroom
is equipped with a J.A. Woolam M-2000V Ellipsometer and Nikon 66 microscope.
For current availible tools, please check Tool Status. For tool scheduling, please check UNT FOM.

The Laurell WS-650 Spin Coater is compact and packed with advanced features. This
650-series coater system will accommodate up to ø150mm wafers and 5" × 5" (127mm ×
127mm) substrates, and features a maximum rotational speed of 12,000 RPM (based on
a ø100mm silicon wafer).
Oerlikon Ion Assist Ebeam and Sputtering system:
Substrate heater: up 1000 degree C.
Nano-Master, Inc. NEE-4000 Electron Beam Evaporation Systems come in a dual chamber
configuration consisting of the main chamber where platen is located and a secondary
chamber for housing the e-beam source. This configuration with a gate valve between
two chambers may be used as a load lock to keep the e-beam source pockets in vacuum
while substrate is loaded and unloaded from the main chamber substrate holder or platen.
On other applications where automatic loading and unloading of wafers is needed, it
can be achieved through a third load lock chamber that may be attached to the left
face of the cube. Co-evaporation capability with multiple e-beam sources and ability
to program compositions or compositional gradients through PC control can be provided.
