Preface: Special Issue on Large Scale Integration

The interests of the solid-state circuits community have been focused on integrated circuits during the past several years. Through a potent combination of technological and economic factors, the development of digital integrated circuits has progressed at a particularly rapid rate during this petiod. At present, large scale integration represents the region of singular importance in the field of digital integrated circuits. Typically, large scale integration consists of the combination of a multiplicity of circuit elements within a basic cell and the further combination of a multiplicity of cells in a monolithic structure to form a highly complex integrated circuit or an integrated equipment component. A most significant feature of an integrated equipment component is the uniquely intimate interdependence of its material, device, circuit, and system-design considerations. Recognizing this interdependence, the central position of large scale integration in electronics and its salient importance in solid-state circuits, the purpose of this issue is to act as an expose of advanced work being done in this field.
