    摘要: Methods and structures for interconnects in semiconductor devices are described. A method of forming a mask pattern for a metal layer in an interconnect can include searching a layout for a metal feature with a predetermined size and an interconnect layer aligned thereto, removing the metal feature from the layout to form a modified layout, and reforming the mask pattern using the modified layout. The metal interconnect may include a first pattern of metal lines, each having a minimum feature size in a layout view in no more than one dimension; a dielectric layer on or over the first pattern of metal lines, having a substantially planar horizontal upper surface; and vias or contacts in the dielectric layer, the vias or contacts contacting a top surface of the first pattern of metal lines and a top surface of silicon structures, vias, or contacts below the first pattern of metal lines.

    摘要: Methods for forming a bipolar junction transistor device are described herein. A method for forming the bipolar junction transistor device may include doping a first portion of a substrate with a first dopant to form a base pick-up region, and after doping the first portion of the substrate, doping a second portion of the substrate with a second dopant to form at least one emitter region. A bipolar junction transistor device may include a floating collector, in which case the bipolar junction transistor device may be operated as a diode for improved emitter current.
