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.

Naomaster Dual Ebeam deposition system

Dual Ebeam Evaporator

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.
