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

System Control
Pumping
The figure shows the pumping screen. Pumping
screens have valves and pumps. The pump and
valve are easily operated with one touch |
|
|
Servo
The picture shows the servo screen. When you press the target button on this screen, target is rotated and you can see the target you selected. It also includes a target trigger function.
|
Shutter
This screen shows the shutter screen. There are buttons on the screen to operate the substrate shutter, the gas valve, and the sputter gun shutter. |
|
|
Gauge Control
This screen shows the gauge control screen. There are buttons on the screen to operate the guage on/off, set point set, Ion gauge on/off. |
Interlock
This picture shows the interlock screen. Basically, the interlock is set so that it does not work when you deviate from the correct method of use for your safety. |
