A wafer treating method for making adhesive chips is provided. A liquid adhesive with two-stage property is coated on a surface of a wafer. Then, the wafer is pre-cured to make the liquid adhesive transform an adhesive film having B-stage property which has a glass transition temperature between -40 and 175 degree C., for example. After positioning the wafer, the wafer is singulated to form a plurality of chips with adhesive for chip-to-chip stacking, chip-to-substrate or chip-to-lead frame attaching.
