Abstract:
An ion implantation system has a first chamber and a process chamber with a heated chuck. A controller transfers the workpiece between the heated chuck and first chamber and selectively energizes the heated chuck first and second modes. In the first and second modes, the heated chuck is heated to a first and second temperature, respectively. The first temperature is predetermined. The second temperature is variable, whereby the controller determines the second temperature based on a thermal budget, an implant energy, and/or an initial temperature of the workpiece in the first chamber, and generally maintains the second temperature in the second mode. Transferring the workpiece from the heated chuck to the first chamber removes implant energy from the process chamber in the second mode. Heat may be further transferred from the heated chuck to a cooling platen by a transfer of the workpiece therebetween to sequentially cool the heated chuck.

Claim (Index 16):
An ion implantation system, comprising:\n an ion implantation apparatus configured to direct an ion beam toward a process chamber; a first chamber operably coupled to the process chamber; a heated chuck positioned within the process chamber, wherein the heated chuck is configured to selectively clamp a workpiece to a clamping surface thereof, wherein the heated chuck comprises a heating apparatus configured to selectively heat the clamping surface of the heated chuck; a workpiece transfer apparatus configured to transfer the workpiece between the heated chuck and the first chamber; and a controller configured to selectively transfer the workpiece between the heated chuck and the first chamber via the workpiece transfer apparatus, and wherein the controller is configured to selectively energize the heating apparatus to operate the heated chuck in each of a first mode and a second mode, wherein in the first mode, the heating apparatus heats the clamping surface to a first temperature, and wherein in the second mode, the heating apparatus heats the clamping surface to a second temperature, and wherein the first temperature is predetermined and associated with a high temperature ion implantation, and wherein the second temperature is associated with a quasi-room temperature ion implantation, wherein the controller is configured to determine the second temperature based on a thermal budget associated with the workpiece, an implant energy associated with the ion beam impacting the workpiece, and an initial temperature of the workpiece when the workpiece resides in the first chamber, wherein the controller is configured to generally maintain the second temperature on the heated chuck in the second mode, and wherein transferring the workpiece from the heated chuck to the first chamber generally removes the implant energy from the process chamber when the heated chuck is operated in the second mode.
