How do RF and DC sputtered metallic thin films differ?

WebSep 26, 2024 · The RF voltage induces oscillations in the particles, with the light electrons accelerating faster and moving further; they are said to have greater mobility. Consequently more electrons bump into the target than do ions. The target picks up their negative charge and hence gains a negative DC bias. WebMar 11, 2014 · Typically, RF makes a better thin film than DC, pulsed DC, or AC. The RF-sputtered film will be smoother and have better packing density. RF also deposits the film at about 20% of the DC rate.If you want to sputter using DC, pulsed DC, or AC, you must … lemon bars with shortbread crust recipe https://sienapassioneefollia.com
