    摘要: Warping of a clamping ring, by which a series of semiconductor wafers is held to a wafer holder for vapor deposition of coatings onto the wafers, is retarded by providing a clamping ring formed of the material having a coefficient of thermal expansion that is approximately the same as or close to that of the coating material being deposited onto the wafers. Preferably also, the material of which the ring is formed has a high modulus of elasticity, high thermal conductivity and a high yield strength. For the deposition of tantalum and gold, which is useful for providing backside thermal conductivity on semiconductor wafers, a clamping ring of molybdenum is preferred. The onset of excessive warping is delayed by replacing clamping rings with clamping rings formed of a material having a thermal expansion coefficient closer to that of the material to be deposited, and preferably having the other preferred properties. Preferably, the clamping ring is one having a generally circular opening that is slightly smaller than the wafers to be clamped and that has a flat edge on the inner edge of the ring corresponding to the orientation flat found on the outer edge of an industry standard wafer, so that the ring engages the wafer during clamping around the entire outer rim of the wafer. A ring having a small number of discrete mounting points for spring attachment to the holder, and having a set of latches connected thereto, is preferred.

    摘要: A substrate support platform has a substrate engaging surface which defines a first channel for introducing and distributing a thermal transfer gas to a first region of the engaging surface, and a second channel, nonintersecting with the first channel, for introducing and distributing a thermal transfer gas to a second region of the engaging surface. A gas delivery system is independently connected between a gas source and the first and second channels, for independently providing (via valved connections) a thermal transfer gas to the first and second channels, so that gas delivery may be limited to one of the channels, or gas may be delivered to both of the channels in case a substrate is placed over either or both of the associated regions. A pressure measuring device is independently coupled to each of the channels via measuring ports, permitting measurement and control of gas pressure from the gas source.

    摘要: A device for rotating a substrate in a complex motion within a chamber which during a sputtering process. The device includes a first support element positioned within the chamber. The first support element includes a first rotating structure which is affixed between a platform for supporting the substrate and a first magnet positioned adjacent to the inner wall surface. Further, the first rotating structure is adapted to rotate about a first axis. The device further includes a second support element positioned outside of the chamber. The second support element includes a second rotating structure affixed between a planet gear adapted for engagement with a sun gear outside of the chamber and a second magnet positioned adjacent the outer wall surface and spaced apart from the first magnet. This causes the formation of a magnetic bond between the first and second magnets. Further, the second rotating structure is adapted to rotate about the first axis thereby enabling the first and second rotating structures to rotate in unison about the first axis. In addition, the device includes a drive element affixed to the first and second support elements, wherein rotation of the drive element causes a first rotation of the first and second rotating elements and thus the substrate about a center axis. This also causes a second rotation wherein the engagement of the sun gear and the planet gear causes simultaneous rotation of the substrate about the first axis.

    摘要: A compact and economical physical vapor deposition (PVD) module for depositing thin film multi-layers with extreme control of thickness, uniformity and surface smoothness. The module includes multiple deposition sources positioned in a conical cluster with confocal arrangement about a single common deposition zone that is defined by a deposition aperture and a substrate carrier with two independently controlled (rotation and scanning) substrate motions. A substrate carrier rotates the substrate at high speed and translates the substrate through the deposition zone. The module lacks a shutter for controlling the film deposition process. Methods of depositing thin film multi-layers are also described.

    摘要: A method and system for producing a film (preferably a thin film with highly uniform or highly accurate custom graded thickness) on a flat or graded substrate (such as concave or convex optics), by sweeping the substrate across a vapor deposition source operated with time-varying flux distribution. In preferred embodiments, the source is operated with time-varying power applied thereto during each sweep of the substrate to achieve the time-varying flux distribution as a function of time. A user selects a source flux modulation recipe for achieving a predetermined desired thickness profile of the deposited film. The method relies on precise modulation of the deposition flux to which a substrate is exposed to provide a desired coating thickness distribution.
