Ion-beam Sculpting - Basis

Basis

The first step in ion sculpting is to make either a through hole or a blind hole, most commonly using an focused ion beam (FIB). The holes are commonly ~100 nm, but can be made much smaller. This step may or may not be done at room temperature, with a low temperature of -120 C. Next, there are three common techniques to now 'sculpt' the hole: broad area ion exposure, TEM exposure, and FIB exposure. Holes can be closed completely, but also they can be left open at a lower limit of 1 - 10 nm.

Famous quotes containing the word basis:

    Self-alienation is the source of all degradation as well as, on the contrary, the basis of all true elevation. The first step will be a look inward, an isolating contemplation of our self. Whoever remains standing here proceeds only halfway. The second step must be an active look outward, an autonomous, determined observation of the outer world.
    Novalis [Friedrich Von Hardenberg] (1772–1801)

    Reason looks at necessity as the basis of the world; reason is able to turn chance in your favor and use it. Only by having reason remain strong and unshakable can we be called a god of the earth.
    Johann Wolfgang Von Goethe (1749–1832)

    Brutus. How many times shall Caesar bleed in sport,
    That now on Pompey’s basis lies along,
    No worthier than the dust!
    Cassius. So oft as that shall be,
    So often shall the knot of us be called
    The men that gave their country liberty.
    William Shakespeare (1564–1616)
