Written by: Richard Bothell and Justin Bothell, Atlas Technologies; Glen Tisdale, Judith Offerle, UHV Aluminum Company Achieving sub-micron feature sizes on a production basis requires an understanding of the complete processing environment including the vacuum reactor itself. Molecular level chemical contamination demands that all processes factor in the vacuum environment. The vacuum system base pressures are a critical parameter in determining the environmental contribution to wafer contamination. Actual processing levels may be decades above the base pressure, but the base pressure establishes the environmental noise of the system.

Our customers at Dynavac were crucial participants in a compelling project for NASA’s Magnetospheric Multiscale Mission at the Goddard Space Center. The Solar Terrestrial Probes mission were scheduled to fly four identically instrumented satellites to investigate how the sun and Earth’s magnetic fields transfer energy from one to the other. This transfer, called Magnetic Reconnection, affects space weather and by studying it, scientists at NASA gained the ability to observe how this process affects systems like communications networks, GPS navigation, and power grids back on Earth. Dynavac, an industry leader in the design and manufacture of thermal vacuum systems, supplied the project with aluminum cryopanel assemblies that allowed for thermal isolation of the satellites while they went through space simulation exercises in the lab prior to their journey in space. Each assembly was comprised of multiple panels joined together to form a thermally controlled and uniform test area. Aluminum extrusion was welded to each of the panels in a serpentine pattern which ultimately connected to stainless steel lines that delivered the liquids and gases to the assembly.  Dynavac uses Atlas ATCR fittings to provide a compatible, demountable transition from the aluminum lines to their stainless-steel counterparts. Atlas has supplied Dynavac with thousands of ATCR fittings for the manufacture of their equipment.

Several Atlas aluminum vacuum chambers with breadboards installed at Max Born in Berlin are used for the generation and application of ultra short x-ray pulses via a frequency conversion process called high order harmonic generation. The purpose is to record films of atoms and molecules on their natural time scales from the femtosecond (10^-15 seconds) to the attosecond (10^-18 seconds) range to capture atomic and molecular reactions. Reliable vacuum is essential to the process because the pulses absorb air. The rectangular shape and accompanying breadboard allows the team to strategically and simultaneously position several optical elements for ease of filtering and focusing on the x-ray pulses. This permits additional laser pulses, from the near-infrared to the ultraviolet regime, to overlap with the x-ray pulses in order to make the atomic and molecular recordings.  Aluminum, says Dr. Bernd Schϋtte of Max Born, is the material of choice for the chambers because “it is cost effective and its low weight eases the handling of the chambers.”
