Abstract:
Embodiments of the invention relate to apparatuses and methods for depositing materials on substrates during atomic layer deposition processes. In one embodiment, a chamber for processing substrates is provided which includes a chamber lid assembly containing an expanding channel extending along a central axis at a central portion of the chamber lid assembly and a tapered bottom surface extending from the expanding channel to a peripheral portion of the chamber lid assembly. The tapered bottom surface may be shaped and sized to substantially cover the substrate receiving surface. The chamber lid assembly further contains a conduit coupled to a gas passageway, another conduit coupled to another gas passageway, and both gas passageways circumvent the expanding channel. Each of the passageways has a plurality of inlets extending into the expanding channel and the inlets are positioned to provide a circular gas flow through the expanding channel.

Embodiments of the invention relate to apparatuses and methods for depositing materials on substrates during atomic layer deposition processes. In one embodiment, a chamber for processing substrates is provided which includes a chamber lid assembly containing a centrally positioned gas dispersing channel, wherein a converging portion of the gas dispersing channel tapers towards a central axis of the gas dispersing channel and a diverging portion of the gas dispersing channel tapers away from the central axis. The chamber lid assembly further contains a tapered bottom surface extending from the diverging portion of the gas dispersing channel to a peripheral portion of the chamber lid assembly, wherein the tapered bottom surface is shaped and sized to substantially cover the substrate and two conduits are coupled to gas inlets within the converging portion of the gas dispersing channel and positioned to provide a circular gas flow through the gas dispersing channel.

Abstract:
A process kit for use in a physical vapor deposition (PVD) chamber, along with a PVD chamber having a non-contact process kit are provided. In one embodiment, a process kit includes a generally cylindrical shield that has a substantially flat cylindrical body, at least one elongated cylindrical ring extending downward from the body, and a mounting portion extending upwards from an upper surface of the body. In another embodiment, a process kit includes a generally cylindrical deposition ring. The deposition ring includes a substantially flat cylindrical body, at least one downwardly extending u-channel coupled to an outer portion of the body, an inner wall extending upward from an upper surface of an inner region of the body, and a substrate support ledge extending radially inward from the inner wall.

Abstract:
The present disclosure provides methods for etching through-silicon vias (TSVs) in a substrate. The method employs a cyclic polymer passivation layer deposition, depassivation process and plasma etching process. By alternating the duration performed in the plasma etching process and the polymer passivation deposition process during the TSVs formation process, a good sidewall profile and via depth control may be obtained.

Methods and apparatus for in-situ plasma cleaning of a deposition chamber are provided. In one embodiment a method for plasma cleaning a deposition chamber without breaking vacuum is provided. The method comprises positioning a substrate on a susceptor disposed in the chamber and circumscribed by an electrically floating deposition ring, depositing a metal film on the substrate and the deposition ring in the chamber, grounding the metal film deposited on the deposition ring without breaking vacuum, and removing contaminants from the chamber with a plasma formed in the chamber without resputtering the metal film on the grounded deposition ring and without breaking vacuum.
