Abstract: Aspects of the present disclosure control aging of a signal path in an idle mode to mitigate aging. In one example, an input of the signal path is alternately parked low and high over multiple idle periods to balance the aging of devices (e.g., transistors) in the signal path. In another example, a clock signal (e.g., a clock signal with a low frequency) is input to the signal path during idle periods to balance the aging of devices (e.g., transistors) in the signal path. In another example, the input of the signal path is parked high or low during each idle period based on an aging pattern.

Abstract: An integrated circuit with BEOL interconnects may comprise: a substrate including a semiconductor device; a first layer of dielectric over the surface of the substrate, the first layer of dielectric including a filled via for making electrical contact to the semiconductor device; and a second layer of dielectric on the first layer of dielectric, the second layer of dielectric including a trench running perpendicular to the longitudinal axis of the filled via, the trench being filled with an interconnect line, the interconnect line comprising cross-linked carbon nanotubes and being physically and electrically connected to the filled via. Cross-linked CNTs are grown on catalyst particles on the bottom of the trench using growth conditions including a partial pressure of precursor gas greater than the transition partial pressure at which carbon nanotube growth transitions from a parallel carbon nanotube growth mode to a cross-linked carbon nanotube growth mode.

Abstract: Methods and apparatus for removing oxide from a surface, the surface comprising at least one of silicon and germanium, are provided. The method and apparatus are particularly suitable for removing native oxide from a metal silicide layer of a contact structure. The method and apparatus advantageously integrate both the etch stop layer etching process and the native oxide removal process in a single chamber, thereby eliminating native oxide growth or other contaminates redeposit during the substrate transfer processes. Furthermore, the method and the apparatus also provides the improved three-step chemical reaction process to efficiently remove native oxide from the metal silicide layer without adversely altering the geometry of the contact structure and the critical dimension of the trenches or vias formed in the contact structure.

Abstract: The present invention generally provides a method and apparatus for forming a doped layer on a substrate to improve uniformity of subsequent deposition thereover. Preferably, the layer is deposited by a sputtering process, such as physical vapor deposition (PVD) or Ionized Metal Plasma (IMP) PVD, using a doped target of conductive material. Preferably, the conductive material, such as copper, is alloyed with a dopant, such as phosphorus, boron, indium, tin, beryllium, or combinations thereof, to improve deposition uniformity of the doped layer over the substrate surface and to reduce oxidation of the conductive material. It is believed that the addition of a dopant, such as phosphorus, stabilizes the conductive material surface, such as a copper surface, and lessens the surface diffusivity of the conductive material.

Abstract: The present invention generally provides a method for stabilizing a halogen-doped silicon oxide film, particularly a fluorinated silicon oxide film. The invention also provides a method for preventing loosely bonded halogen atoms from reacting with components of the barrier layer during subsequent processing of the substrate. The invention provides a hydrogen plasma treatment of the halogen-doped silicon oxide film without subjecting the substrate to a heated environment that may damage the substrate and the structures formed on the substrate. The invention also improves the adhesion strength between the halogen-doped silicon oxide film and the barrier layer. Furthermore, the hydrogen plasma treatment can be practiced in a variety of plasma processing chambers of an integrated process sequence, including pre-clean chambers, physical vapor deposition chambers, chemical vapor deposition chambers, etch chambers and other plasma processing chambers.

Abstract: The present invention provides a method and apparatus for forming a copper layer on a substrate, preferably using a sputtering process. The sputtering process involves bombarding a conductive member of enhanced hardness with ions to dislodge the copper from the conductive member. The hardness of the target may be enhanced by alloying the copper conductive member with another material and/or mechanically working the material of the conductive member during its manufacturing process in order to improve conductive member and film qualities. The copper may be alloyed with magnesium, zinc, aluminum, iron, nickel, silicon and any combination thereof.

Abstract: Coils for use within high density plasma chambers are provided that do not electrically disconnect or short circuit following repeated depositions and that produce films having reduced in-film defect densities. To reduce in-film defect densities, dielectric inclusion content, porosity, grain size and surface roughness of a coil are reduced, while the mechanical strength of the coil is increased so as to both decrease defect generation and thermal creep rate (e.g., to prevent electrical disconnection or short circuiting of the coil following repeated depositions).
