摘要:
The present invention relates to dilute aqueous solutions containing phosphoric acid and methods for cleaning plasma etch residue from semiconductor substrates including such dilute aqueous solutions. The solution according to the invention may advantageous contain an alkaline compound, one or more other acid compounds, and/or a fluoride-containing compound and may optionally contain additional components such as organic solvents, chelating agents, amines, and/or surfactants.
摘要:
A composition for the stripping of photoresist and the cleaning of residues from substrates, and for silicon oxide etch, comprising from about 0.01 percent by weight to about 10 percent by weight of one or more fluoride compounds, from about 10 percent by weight to about 95% by weight of a sulfoxide or sulfone solvent, and from about 20 percent by weight to about 50 percent by weight water. The composition may contain corrosion inhibitors, chelating agents, co-solvents, basic amine compounds, surfactants, acids and bases.

A linear accelerator drift tube is formed by a casting technique. Coolant circualting grooves are integrally formed in the central body of the drift tube as well as face plates. This minimizes the temperature of the drift tube in an operating environment thereby maximizing the R.F. efficiency of the unit. The face plates are attached to the central body of the drift tube by means of a solder/electroform joining. The stem of the drift tube includes concentric passages integrally formed in the cast central body which enables efficient circulation of coolant through the drift tube.

A first embodiment of an ammunition clip reloading device comprises an L-shaped member attachable to the pin associated with the spring of a conventional clip. An outwardly extending portion of the member is designed to receive the thumb of a user so as to depress the clip spring to thus make the loading of ammunition substantially easier. A second embodiment of the invention comprises a thumb manipulated slide member positionable over a conventional ammunition clip. An adjustable guide extends above the body portion of the member and is operable to push a bullet into the clip in response to a downward pressure by the user's thumb.
