Plasma etching/Gases. The type and ratio of gases used in a plasma etch is chosen depending on the material being etched, the masking material, and the etch stop material. Ideally, the gas mixture will react readily with the material being etched, while reacting minimally with materials that should not be etched, thus achieving high selectivity.

A final milling process at a 2 kV accelerating voltage was performed to remove approximately the top 20 nm of damaged material produced by the high-energy Ga + ion implantation. TEM methods

Ion Milling • Uses a broad-beam Kaufman-type ion source which can separate the energizing plasma from the substrates. – Can reduce plasma damage. Allows a more intense plasma to be used as the source, e.g. an inductively coupled source. – Can increase the milling etch rate. Higher acceleration energies can be achieved.

The vertical milling machine is a precision tool used for shaping and fabrication by the removal of stock typically from metallic work pieces. Plastics and other materials can also be machined on the mill depending upon tooling and material. Mill controls may be manually operated, computer numerical controlled (CNC), or a combination of both.

Fuel Dumping. When information is received that an aircraft plans to dump fuel, determine the route and altitude it will fly and the weather conditions in which the operation will be conducted. Except when it is dumping fuel for emergency reasons, an aircraft in either VFR or IFR conditions may be requested to fly a different route.
