Abstract

Official abstract text for this publication.

A workpiece is implanted to affect growth of a compound semiconductor, such as GaN. Implanted regions of a workpiece increase, reduce, or prevent growth of this compound semiconductor. Combinations of implants may be performed to cause increased growth in certain regions of the workpiece, such as between regions where growth is reduced. Growth also may be reduced or prevented at the periphery of the workpiece.

First claim

Opening claim text (preview).

What is claimed is: 1. A method of workpiece processing comprising: selecting a first species of ion such that said first species reduces a rate of compound semiconductor growth on regions in a workpiece implanted with said first species; implanting a first plurality of implanted regions in a workpiece with said first species using a mask disposed above and a distance from said workpiece; and growing a compound semiconductor on said workpiece after said implanting, w…
