Multilayer Mirrors Imager for Magnetopause to Aurora Global Exploration (IMAGE) – “It’s a weather satellite for space storms” -Dr. James L. Burch Lithography and High-Resolution Microscopy
3
Ceramics and Glass Applications Use In Metal-Oxide Semiconductor devices Catalyst in for chemical reactions High-temperature superconductor YBCO produce phosphors, which provide the red color in color television tubes NASA rocket combustion chamber. The silver-colored lining is a highly robust alloy of Nickel, Chromium, Aluminum and Yttrium (Photo: NASA)
4
Reactively Sputtered Surface Anneal Cleaning Methods Measurement using Ellipsometry Identification and Record Keeping
5
Theories Tested Film oxidation Too thick New Deposition Blank Silicon Wafer- no growth Oxidation of Silicon Substrate Thickness decreased in furnace
6
Importance of Distance from VUV Lamp
7
Formation of an Ozonide
8
Water Expansion Ding Lamp Exposure
9
Necessity of VUV Interaction with Sample
10
Formation of Nitrogen Containing Product
11
Use TEM (Transmission Electron Microscope) to characterize new material being formed Figure out how to transfer the new material onto the delicate TEM grid Sputtering destroys grids VUV process destroys grids
