The ion mill generates high-energy particles to remove material off the surface of a specimen, similar to how sand and dust particles wear away at rocks in a canyon to create a smooth surface. Relative to other techniques, ion milling creates much less surface damage, [1] which makes it perfect for surface-sensitive analytical techniques. This ...
Ion milling, or sputter etching, uses lower pressures, often as low as 10 −4 Torr (10 mPa). It bombards the wafer with energetic ions of noble gases, often Ar +, which knock atoms from the substrate by transferring momentum. Because the etching is performed by ions, which approach the wafer approximately from one direction, this process is ...
Veeco Instruments Inc. is a global capital equipment supplier, headquartered in the U.S., that designs and builds processing systems used in semiconductor and compound semiconductor manufacturing, data storage and scientific markets for applications such as advanced packaging, photonics, power electronics and display technologies.
A milled printed circuit board. Printed circuit board milling (also: isolation milling) is the milling process used for removing areas of copper from a sheet of printed circuit board (PCB) material to recreate the pads, signal traces and structures according to patterns from a digital circuit board plan known as a layout file.

FIB systems operate in a similar fashion to a scanning electron microscope (SEM) except, rather than a beam of electrons and as the name implies, FIB systems use a finely focused beam of ions (usually gallium) that can be operated at low beam currents for imaging or at high beam currents for site specific sputtering or milling. As the diagram ...
Ion implantation setup with mass separator. Ion implantation equipment typically consists of an ion source, where ions of the desired element are produced, an accelerator, where the ions are electrostatically accelerated to a high energy or using radiofrequency, and a target chamber, where the ions impinge on a target, which is the material to be implanted.
Reactive-ion etching (RIE) is an etching technology used in microfabrication. RIE is a type of dry etching which has different characteristics than wet etching . RIE uses chemically reactive plasma to remove material deposited on wafers .
