Overview
PLD (Pulsed Laser Deposition) is a physical deposition method that utilizes a high energy
focused laser. Conceptually and experimentally. PLD is extremely simple. It consists of a
target holder and a substrate holder housed in a vacuum chamber. A set of optical
components focus and raster a high-power laser (the external source) into a
concentrated beam over the target surface which vaporizes target materials to
ultimately deposite thin film.
Advantages
≻ Allows for the use of various targets and for the in-situ deposition of multi-layers
≻ Consists of simple hardware
≻ Simple system maintenance
≻ Various aspect of beam-target-substrate positioning
≻ Temperature uniformity of substrate
≻ Pyrometer Port
≻ Laser strength measurement port
≻ Ellipsometry port
