Patent ID: 10538840

Abstract:
A method for depositing film on a substrate (16) through pulsed laser deposition, which includes: generating at least two pulsed laser beams (4, 5, 6) with at least one laser (1), and directing the at least two laser beams (4, 5, 6) to different target spots (9, 10, 11) of a target (12), whereby the target (12) is ablated and at least two plasma plumes (13) are created. The plasma plumes (13) create a flow of target material towards the substrate (16) and the target material is deposited onto the substrate (16) at a deposition area (24). The plasma plumes (13) created by the at least two laser beams (4, 5, 6) are spatially and temporally superimposed, and the target spots (9, 10, 11) are separated from each other at a distance that allows a gas-dynamical interaction of the created plasma plumes (13).
