Abstract

Methods for monolithic integrated circuit construction are presented wherein component device-isolating region self-alignment is provided and also, where an element of the device is provided through independent dopant provision steps to allow design flexibility in providing that device element and associated integrated circuit devices. The method is especially applicable to bipolar device construction.
