Abstract
An integrated circuit structure is provided in which component isolation is achieved after all diffused junction formation is complete. An anisotropically etched moat provides isolation. The surfaces of the moat are lined with oxide and a planar wafer surface is restored by filling the moat with metal. The subsurface metal region can then be used as a conductor for component interconnection.
