    Abstract: A method is disclosed for isolating device regions in a heterostructure that includes at least one layer of a strained semiconductor material. The method includes the steps of forming a trench in the at least one layer of strained semiconductor material using an etch chemistry that is selected to etch different layers of said heterostructure sufficiently similarly that said trench includes walls that are substantially straight, and depositing a dielectric material in the trench.
