 + 
 +The sputtering of thin films has some advantages over vapor deposition: 
 +  - Sputtered films **adhere more strongly** to substrates than vapor deposited films, due to the high kinetic energies with which the atoms impinge upon the substrate (1-100 eV for sputtering, 0.1-0.5 eV for evaporation). 
 +  - Sputtered films are typically denser and more uniform. 
 +  - The sputtering process is more versatile. The target may be composed of alloys or composite materials in addition to pure metals. Furthermore, //reactive sputtering// is a well established technique for creating compound materials such as NbTiN. 
 +  - Both conductive (metals, alloys) and nonconductive (dielectrics, insulators) films may be deposited. (Although 
 +  - The process may be used in a reverse mode just to clean the surface of the substrates prior to sputtering. 
 +  - Sputtering is isotropic, thus covering step-edges, whereas vapor deposition is line-of-sight, enabling techniques such as //shadow evaporation//

 +====== Calibrations ====== 
 + 
 +For machines that do not have [[Quartz_Crystal_Monitors|quartz crystal monitors]] (which most sputtering system generally don't, while vapor deposition systems generally do have this), thickness calibrations are necessary every once in a while. Such calibrations can be found on the page of each deposition system. 
 +It is crucial to include **all** relevant information about the process.
