The IBD (Ion Beam Deposition) System

The IBD comes equipped with a Commonwealth 12 cm DC ion source for uniform etching and an 8 cm ion source for ion beam deposition. The target selector contains 4 materials at any given time (currently: Al203, SiO2, C, Cu). The stage is chiller-cooled and has automatic stage spin.

Intlvac Nanoquest Ion Etch System w/ Endpoint Detector

The Intlvac Ion Etch system features a Commonwealth 12 cm DC ion source for uniform etching over wide areas. An attached Hiden SIMS detector allows real-time detection of etched material making this tool ideal for mill-stop with accuracies less than 1 nm. Stage angle and spin are stepper motor controlled with stage angle accuracy of .1 degrees.

AJA 7-Gun Sputtering System

The AJA is a load-locked seven gun magnetron sputtering system with 1 RF and 5 DC power supplies. Typical base pressures are around 4x10-9 torr. Additional gas options are nitrogen, oxygen, and hydrogen. The system is capable of in-situ annealing up to 450 C.

D7 Growth and Characterization Chamber

This chamber is, in fact, many connected chambers which can be valved off from each other. The various chambers include an electron-gun evaporator, a 5-gun magnetron sputter system, and two STMs for surface topography and LDOS information as well as for BEEM (Ballistic Electron Emission Microscopy). Samples can be loaded into a vacuum jacket for transfer into the XPS.

XPS with Loadlock

We use X-Ray Photoelectron Spectroscopy (XPS) for thin-film surface characterization. It utilizes monochromated X-Rays to eject core secondary electrons which are collected and energy-analyzed. Careful analysis of the data can reveal quantitative information on film surface stoichiometry and bonding. This system has base pressure of 9x10-10 and can accomodate vacuum sample transfer.
