sputter
v.
eject bits of food or water from the mouth while making explosive sounds; make popping or exploding sounds
Sputtering
Sputtering is a process whereby
particles are ejected from a solid target material due to bombardment of the target by energetic
particles. It only happens when the kinetic energy of the incoming particles is much higher than conventional thermal energies (
» 1
eV). This process can lead, during prolonged ion or plasma bombardment of a material, to significant erosion of materials, and can thus be harmful. On the other hand, it is commonly utilized for
thin-film deposition, etching and analytical techniques.

About
Sputtering
a process used to deposit materials where a plasma is used to generate ions, the ions are attracted to a target, the ions impact the target and physically knock loose target atoms, and the atoms knocked loose condense out on wafers placed in the chamber depositing a film. Sputtering is primarily used to deposit metal films. Sputtering is preferred over evaporation because sputtering will transfer a metal alloy from a target to a wafer with roughly the same composition on the wafer as in the target. Evaporation deposits elements at different rates depending on vapor pressure so the film on the wafer may not match the composition of the target. See also, tech brief on
Sputtering.
