  • Patent number: 10480095
    Abstract: A system and methods are provided for low temperature, rapid baking to remove impurities from a semiconductor surface prior to in-situ deposition. The system is configured with an upper bank of heat elements perpendicular to the gas flow path, such that when the substrate is heated, the temperature across the substrate can be maintained relatively uniform via zoned heating. Advantageously, a short, low temperature process is suitable for advanced, high density circuits with shallow junctions. Furthermore, throughput is greatly improved by the low temperature bake.

  • Patent number: 9593416
    Abstract: A precursor source vessel comprises a vessel body, a passage within the vessel body, and a valve attached to a surface of the body. An internal chamber is adapted to contain a chemical reactant, and the passage extends from outside the body to the chamber. The valve regulates flow through the passage. The vessel has inlet and outlet valves, and optionally a vent valve for venting internal gas. An external gas panel can include at least one valve fluidly interposed between the outlet valve and a substrate reaction chamber. Gas panel valves can each be positioned along a plane that is generally parallel to, and no more than about 10.0 cm from, a flat surface of the vessel. Filters in a vessel lid or wall filter gas flow through the vessel's valves. A quick-connection assembly allows fast and easy connection of the vessel to a gas panel.

  • Patent number: 9466574
    Abstract: Methods of forming a conductive metal layer over a dielectric layer using plasma enhanced atomic layer deposition (PEALD) are provided, along with related compositions and structures. A plasma barrier layer is deposited over the dielectric layer by a non-plasma atomic layer deposition (ALD) process prior to depositing the conductive layer by PEALD. The plasma barrier layer reduces or prevents deleterious effects of the plasma reactant in the PEALD process on the dielectric layer and can enhance adhesion. The same metal reactant can be used in both the non-plasma ALD process and the PEALD process.

  • Patent number: 9312131
    Abstract: Epitaxial layers are selectively formed in semiconductor windows by a cyclical process of repeated blanket deposition and selective etching. The blanket deposition phases leave non-epitaxial material over insulating regions, such as field oxide, and the selective etch phases preferentially remove non-epitaxial material while deposited epitaxial material builds up cycle-by-cycle. Quality of the epitaxial material improves relative to selective processes where no deposition occurs on insulators. Use of a germanium catalyst during the etch phases of the process aid etch rates and facilitate economical maintenance of isothermal and/or isobaric conditions throughout the cycles. Throughput and quality are improved by use of trisilane, formation of amorphous material over the insulating regions and minimizing the thickness ratio of amorphous:epitaxial material in each deposition phase.
