Abstract
Localized epitaxial growth of GaAs from a silicon monocrystalline substrate to provide a three-dimensional Si-GaAs structure and method. The silicon has an insulating layer deposited thereover and a window is opened through the layer to expose a small area of the underlying silicon from which silicon is epitaxially grown until the window is nearly full whereupon a thin buffer layer such as germanium is epitaxially grown over the epi-silicon to fill the window. Al.sub.x Ga.sub.1-x As (where x.gtoreq.0) is then locally epitaxially grown from the buffer layer and it grows laterally as well as vertically to cover the surrounding insulating layer surface and provide a site for high frequency electronics.
