Derived forms of sputter sputterer , noun. Word Origin for sputter C from Dutch sputteren, of imitative origin.

Emoji Challenge! When energetic ions collide with atoms of a target material, an exchange of momentum takes place between them. These ions, known as "incident ions", set off collision cascades in the target.

Such cascades can take many paths; some recoil back toward the surface of the target. If a collision cascade reaches the surface of the target, and its remaining energy is greater than the target's surface binding energy , an atom will be ejected.

This process is known as "sputtering". If the target is thin on an atomic scale , the collision cascade can reach through to its back side; the atoms ejected in this fashion are said to escape the surface binding energy "in transmission".

The average number of atoms ejected from the target per incident ion is called the "sputter yield". The sputter yield depends on several things: the angle at which ions collide with the surface of the material, how much energy they strike it with, their masses, the masses of the target atoms, and the target's surface binding energy.

If the target possesses a crystal structure, the orientation of its axes with respect to the surface is an important factor.

The ions that cause sputtering come from a variety of sources -- they can come from plasma , specially constructed ion sources , particle accelerators , outer space e.

A model for describing sputtering in the cascade regime for amorphous flat targets is Thompson's analytical model. Another mechanism of physical sputtering is called "heat spike sputtering".

This can occur when the solid is dense enough, and the incoming ion heavy enough, that collisions occur very close to each other.

In this case, the binary collision approximation is no longer valid, and the collisional process should be understood as a many-body process.

The dense collisions induce a heat spike also called thermal spike , which essentially melts a small portion of the crystal. The heat spike sputtering often increases nonlinearly with energy, and can for small cluster ions lead to dramatic sputtering yields per cluster of the order of 10, Physical sputtering has a well-defined minimum energy threshold, equal to or larger than the ion energy at which the maximum energy transfer from the ion to a target atom equals the binding energy of a surface atom.

That is to say, it can only happen when an ion is capable of transferring more energy into the target than is required for an atom to break free from its surface.

This threshold is typically somewhere in the range of ten to a hundred eV. Preferential sputtering can occur at the start when a multicomponent solid target is bombarded and there is no solid state diffusion.

If the energy transfer is more efficient to one of the target components, or it is less strongly bound to the solid, it will sputter more efficiently than the other.

If in an AB alloy the component A is sputtered preferentially, the surface of the solid will, during prolonged bombardment, become enriched in the B component, thereby increasing the probability that B is sputtered such that the composition of the sputtered material will ultimately return to AB.

The term electronic sputtering can mean either sputtering induced by energetic electrons for example in a transmission electron microscope , or sputtering due to very high-energy or highly charged heavy ions that lose energy to the solid, mostly by electronic stopping power , where the electronic excitations cause sputtering.

One example of this is Jupiter's ice-covered moon Europa , where a MeV sulfur ion from Jupiter's magnetosphere can eject up to 10, H 2 O molecules.

In the case of multiple charged projectile ions a particular form of electronic sputtering can take place that has been termed potential sputtering.

This sputtering process is characterized by a strong dependence of the observed sputtering yields on the charge state of the impinging ion and can already take place at ion impact energies well below the physical sputtering threshold.

Potential sputtering has only been observed for certain target species [13] and requires a minimum potential energy.

Removing atoms by sputtering with an inert gas is called ion milling or ion etching. Sputtering can also play a role in reactive-ion etching RIE , a plasma process carried out with chemically active ions and radicals, for which the sputtering yield may be enhanced significantly compared to pure physical sputtering.

Reactive ions are frequently used in secondary ion mass spectrometry SIMS equipment to enhance the sputter rates.

The mechanisms causing the sputtering enhancement are not always well understood, although the case of fluorine etching of Si has been modeled well theoretically.

Sputtering observed to occur below the threshold energy of physical sputtering is also often called chemical sputtering.

At elevated temperatures, chemical sputtering of carbon can be understood to be due to the incoming ions weakening bonds in the sample, which then desorb by thermal activation.

When done with direct current DC sputtering , voltages of kV are used. When done with alternating current RF sputtering , frequencies are around the 14MHz range.

Surfaces of solids can be cleaned from contaminants by using physical sputtering in a vacuum. Sputter cleaning is often used in surface science , vacuum deposition and ion plating.

In Farnsworth, Schlier, George, and Burger reported using sputter cleaning in an ultra-high-vacuum system to prepare ultra-clean surfaces for low-energy electron-diffraction LEED studies.

When the surfaces to be cleaned are large, a similar technique, plasma cleaning , can be used. Sputter cleaning has some potential problems such as overheating, gas incorporation in the surface region, bombardment radiation damage in the surface region, and the roughening of the surface, particularly if over done.

It is important to have a clean plasma in order to not continually recontaminate the surface during sputter cleaning.

Redeposition of sputtered material on the substrate can also give problems, especially at high sputtering pressures.

Sputtering of the surface of a compound or alloy material can result in the surface composition being changed. Often the species with the least mass or the highest vapor pressure is the one preferentially sputtered from the surface.

Sputter deposition is a method of depositing thin films by sputtering that involves eroding material from a "target" source onto a "substrate" e.

SiO 2 during the deposition also by ion bombardment. Sputtered atoms are ejected into the gas phase but are not in their thermodynamic equilibrium state, and tend to deposit on all surfaces in the vacuum chamber.

A substrate such as a wafer placed in the chamber will be coated with a thin film. Sputtering deposition usually uses an argon plasma because argon, a noble gas, will not react with the target material.

In the semiconductor industry sputtering is used to etch the target. Sputter etching is chosen in cases where a high degree of etching anisotropy is needed and selectivity is not a concern.

One major drawback of this technique is wafer damage and high voltage use. Another application of sputtering is to etch away the target material.

One such example occurs in secondary ion mass spectrometry SIMS , where the target sample is sputtered at a constant rate.

As the target is sputtered, the concentration and identity of sputtered atoms are measured using mass spectrometry. Furthermore, because the sputtering continually etches deeper into the sample, concentration profiles as a function of depth can be measured.

Sputtering is one of the forms of space weathering, a process that changes the physical and chemical properties of airless bodies, such as asteroids and the Moon.

On icy moons, especially Europa , sputtering of photolyzed water from the surface leads to net loss of hydrogen and accumulation of oxygen-rich materials that may be important for life.

Sputtering is also one of the possible ways that Mars has lost most of its atmosphere and that Mercury continually replenishes its tenuous surface-bounded exosphere.
