Sputter deposition - Wikipedia

WebSputter deposition is a physical vapor deposition (PVD) method of thin film deposition by the phenomenon of sputtering. This involves ejecting material from a "target" that is a source onto a "substrate" such as a silicon wafer. Resputtering is re-emission of the deposited material during the deposition process by ion or atom bombardment. Web1 Aug 2016 · The higher gas pressure during sputtering (≈ 10 − 1 Pa compared to 10 − 3 Pa for E-beam) implies an increased collision probability of particles that are moving towards the substrate. The resulting wide angular distribution of the particle drift velocity leads to a covering of the sidewalls of the photoresist lines (see Fig. 1).In this case, the removal of … fisher tips

Web1 Oct 2002 · Conventionally to utilise the lift-off technique a highly directional metal deposition is required, e.g. evaporation. The reason for this is because conformal coverage will protect the photoresist from the dissolving solvent. If the photoresist cannot be dissolved then the metal will not lift-off. Web17 May 2024 · The fabrication process is schematically depicted in ﬁgure 1. The AlO x pattern for the mask was prepared by standard photolithography and lift-off, resulting (after lift-off) in a pattern such as in ﬁgure 1(a), consisting of voids 3×100μm2 on an area of 1cm2.
