    Abstract: A flow inlet element (22) for a chemical vapor deposition reactor (10) is formed from a plurality of elongated tubular elements (64, 65) extending side-by-side with one another in a plane transverse to the upstream to downstream direction of the reactor. The tubular elements have inlets for ejecting gas in the downstream direction. A wafer carrier (14) rotates around an upstream to downstream axis. The gas distribution elements may provide a pattern of gas distribution which is asymmetrical with respect to a medial plane (108) extending through the axis.

    Abstract: A method of in-situ pyrometer calibration for a wafer treatment reactor such as a CVD reactor 12 desirably includes the steps of positioning a calibrating pyrometer 80 at a first calibrating position A and heating the reactor until the reactor reaches a pyrometer calibration temperature. The method desirably further includes rotating a support element 40 about a rotational axis 42, and while the support element is rotating about the rotational axis, obtaining first operating temperature measurements from a first operating pyrometer 71 installed at a first operating position 1R, and obtaining first calibrating temperature measurements from the calibrating pyrometer 80. Both the calibrating pyrometer 80 and the first operating pyrometer 71 desirably are adapted to receive radiation from a first portion of the wafer support element 40 at a first radial distance D1 from the rotational axis 42 of the wafer support element.

    Abstract: The presently disclosed technology provides a responsive ion beam source power supply system (200, 300, 400) capable of handling fault events without relying on conventional protection circuitry (e.g., fuses and breakers) so that physical power supply hardware intervention by a user is minimized for typical fault conditions and the ion beam source power supply system (200, 300, 400) may recover automatically after experiencing a fault condition. The presently disclosed technology further discloses an ion beam source power supply system (200, 300, 400) capable of detecting and diagnosing fault states, autonomously implementing command decisions to preserve or protect the function of other ion source modules or sub-systems, and/or mitigating or recovering from the disruptive fault event and returning the ion beam source system (100) to desired user settings.

    Abstract: Non-elliptical ion beams (508) and plumes (510) of sputtered material can yield a relatively uniform wear pattern on a destination target (504) and a uniform deposition of sputtered material on a substrate assembly (506). The non-elliptical ion beams (508) and plumes (510) of sputtered material impinge on rotating destination targets (504) and substrate assemblies (506). A first example ion beam grid (302) and a second example ion beam grid (304) each have patterns of holes with an offset between corresponding holes. The quantity and direction of offset determines the quantity and direction of steering individual beamlets passing through corresponding holes in the first and second ion beam grids (302, 304). The beamlet steering as a whole creates a non-elliptical current density distribution within a cross- section of an ion beam (508) and generates a sputtered material plume (510) that deposits a uniform distribution of sputtered material onto a rotating substrate assembly (506).

    Abstract: A wafer carrier (32) used in wafer treatments such as chemical vapor deposition has pockets (40,240) for holding the wafers and support surfaces for supporting the wafers above the floors of the pockets. The carrier is provided with locks (50,250) for restraining wafers against upward movement away from the support surfaces (56, 254). Constraining the wafers against upward movement limits the effect of wafer distortion on the spacing between the wafer and the floor surfaces, and thus limits the effects of wafer distortion on heat transfer. The carrier may include a main portion (38) and minor portions (44) having higher thermal conductivity than the main portion, the minor portions being disposed below the pockets.
