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 11):
A method for maintaining temperature consistency in an ion implantation system, the method comprising:\n determining an operation of a heated chuck as being in one of a first mode and a second mode, wherein the first mode is associated with a high temperature ion implantation into a workpiece at a first temperature, wherein the first temperature is predetermined, and wherein the second mode is associated with a quasi-room temperature ion implantation into the workpiece at a second temperature; determining the second temperature based on one or more of a thermal budget associated with the workpiece, an implant energy associated an the ion beam impacting the workpiece, and an initial temperature of the workpiece when the workpiece resides in a first chamber; heating the heated chuck to the first temperature when the ion implantation system is in the first mode; heating the heated chuck to the second temperature when the operation of the ion implantation system is in the second mode; transferring the workpiece from the first chamber to the heated chuck; implanting ions into the workpiece on the heated chuck; and transferring the workpiece from the heated chuck to the first chamber, therein generally removing implant energy associated with the implantation of ions into the workpiece from the heated chuck when the heated chuck is operated in the second mode.
