Chemically-strengthened thin glass having modified curvature and a method for making the same. The method includes providing a thin glass substrate which has host alkali ions situated in its surface regions, and possesses a treatment-advantaged surface region and a treatment-disadvantaged surface region located opposing each other; conducting a step of ion-exchange with invasive alkali ions having an average ionic radius larger than the average ionic radius of the host alkali ions, thereby producing a chemically-strengthened substrate which is characterized by an undesired curvature (warpage), and then conducting a step of reverse ion-exchange with reversing alkali ions having an average ionic radius equal to, or smaller than, the average ionic radius of the host alkali ions before ion-exchange, so as to produce a chemically-strengthened substrate having either less curvature or having a predetermined profile of curvature, which is not present in the chemically-strengthened glass substrate prior to reverse ion-exchange.
