The following invention pertains to the introduction of a gas (or fluid) around
a SPM probe or nanotool to control chemical activity e.g. oxygen to promote
oxidation, argon to inhibit oxidation or clean dry air (CDA) to inhibit moisture
to control static charging due to the action of the probe or nanotools and to provide
vacuum at and around the tip and substrate area. The invention can also produce
electrical current for use with active electronic devices on, in or near the body
of the device. In addition by use of a fluid like water, certain oils, and other
liquids in conjunction with specific tip structure either electric discharge machining
can be used at the tip area on the tip itself (in conjunction with a form structure
on the work piece) or on a work piece beneath the tip to shape, polish and remove
material at very small scales (10 microns to 1 nm or less).
