Abstract
A method for binding a micro device to a substrate is provided. The method includes: locally showering a gas on a portion of the substrate, wherein the gas has a water vapor pressure higher than an ambient water vapor pressure; and placing the micro device over the portion of the substrate after a part of water in the gas is condensed to form a liquid layer on the portion of the substrate and contacting the micro device with the liquid layer, so that the micro device is gripped by a capillary force produced by the liquid layer and is substantially held in a position within a controllable region on the substrate.
