argon ion beam milling ppt

Ion Beam - an overview | ScienceDirect Topics

Ion beam machining (IBM) is an atomic-bit machining process, which is used to machine a product with high resolution of the order of 0.1 μm. Ions of inert gases like argon with high kinematic energy of the order of 10 KeV are used to bombard and eject atoms from workpiece surface by elastic collision [17].

Scalable Fabrication of Metallic Nanogaps at the Sub-10 nm Level

Patterning by ion beams is known as Focused Ion Beam milling and, like EBM, has the advantage of not requiring a resist (see Figure 7a). In a typical set-up, liquid gallium wets a positively biased tungsten needle, causing a beam of Ga + ions to be ejected from the tip. The ions strike a target, causing atoms of the target to sputter from the ...

In essence, an ion beam source is a plasma source having a set of grids that enable extraction of a stream of ions. The three main parts of the ion beam source are the discharge chamber, the grids and the neutraliser. Ion production is done in the discharge chamber by subjecting a gas like argon to an RF field.

Sputtering - Wikipedia

In physics, sputtering is a phenomenon in which microscopic particles of a solid material are ejected from its surface, after the material is itself bombarded by energetic particles of a plasma or gas. It occurs naturally in outer space, and can be an unwelcome source of wear in precision components. However, the fact that it can be made to act on extremely fine layers of material is utilised ...

Ion Beam Polishing of Sample Surfaces - Leica Microsystems

Ion milling can be used to reduce the roughness of sample surfaces. Small angles less than 6° with respect to the sample surface are necessary. The high voltage depends on the material to be prepared. The reason for the levelling effect is the different milling angle of flat and rough surface areas. The milling rate is lower for small angles.
