Sacrificial Capping Layer For Passivation Using Plasma-Based Implant Process
An apparatus and method of processing a workpiece is disclosed, where a sacrificial capping layer is created on a top surface of a workpiece. That workpiece is then exposed to an ion implantation process, where select species are used to passivate the workpiece. While the implant process is ongoing, radicals and excited species etch the sacrificial capping layer. This reduces the amount of etching that the workpiece experiences. In certain embodiments, the thickness of the sacrificial capping layer is selected based on the total time used for the implant process and the etch rate. The total time used for the implant process may be a function of desired dose, bias voltage, plasma power and other parameters. In some embodiments, the sacrificial capping layer is applied prior to the implant process. In other embodiments, material is added to the sacrificial capping layer during the implant process.

FORMING AN OXIDE VOLUME WITHIN A FIN
Embodiments of the present disclosure may generally relate to systems, apparatus, and/or processes to form volumes of oxide within a fin, such as a Si fin. In embodiments, this may be accomplished by applying a catalytic oxidant material on a side of a fin and then annealing to form a volume of oxide. In embodiments, this may be accomplished by using a plasma implant technique or a beam-line implant technique to introduce oxygen ions into an area of the fin and then annealing to form a volume of oxide. Processes described here may be used manufacture a transistor, a stacked transistor, or a three-dimensional (3-D) monolithic stacked transistor.
