METHOD OF FABRICATING AN ELECTROCHEMICAL DEVICE USING ULTRAFAST PULSED LASER DEPOSITION

摘要

A method of fabricating a multi-layered thin film electrochemical device is provided. The method comprises: providing a first target material in a chamber; providing a substrate in the chamber; emitting a first intermittent laser beam directed at the first target material to generate a first plasma, wherein each pulse of the first intermittent laser beam has a pulse duration of about 20 fs to about 500 ps; depositing the first plasma on the substrate to form a first thin film; providing a second target material in the chamber; emitting a second intermittent laser beam directed at the second target material to generate a second plasma, wherein each pulse of the second intermittent laser beam has a pulse duration of about 20 fs to about 500 ps; and depositing the second plasma on or above the first thin film to form a second thin film.
