An IC wafer and the method of making the IC wafer, the IC wafer includes an integrated circuit layer having a plurality of solder pads and an insulated layer arranged thereon, a plurality of through holes cut through the insulated layer corresponding to the solder pads respectively for the implantation of a package layer, and an electromagnetic shielding layer formed on the top surface of the insulated layer and electrically isolated from the solder pads of the integrated circuit layer for electromagnetic sheilding. Thus, the integrated circuit does not require any further shielding mask, simplifying the fabrication. Further, the design of the through holes facilitates further packaging process.
