Abstract
This invention relates to a method for securing a carrier by gas pressurization to inhibit warpage of the carrier. The method includes following steps: provide a carrier with an upper surface and a lower surface which are opposite to each other; providing an evacuable jig with an apertured surface on which a plurality of apertures are provided; placing and securing one of the upper and lower surfaces of the carrier on the apertured surface in a manner of facing the apertured surface, wherein the surface of the carrier faced to the apertured surface is defined as a first surface, and the other surface opposed to the first surface is defined as a second surface; and gas pressurizing a chamber and evacuating the jig positioned in the chamber, to form a pressure difference between the first surface and the second surface of the carrier, whereby the carrier is pressed on the jig, wherein the chamber is pressurized to a predetermined pressure greater than a standard atmospheric pressure.
