  • Publication number: 20080206902
    Abstract: A substrate is disposed within a processing chamber. A nitrogen precursor and a group-III precursor are flowed into the processing chamber. A layer is deposited over the substrate with a thermal chemical-vapor-deposition process at an elevated temperature within the processing chamber using the nitrogen precursor and the group-III precursor. Light beams are directed to a surface of the layer and light spots corresponding to reflections of the light beams are received from the surface at a position-sensitive detector. Positions of the light spots on the position-sensitive detector are determined from photocurrent induced in a photodiode in the position-sensitive detector. A curvature of the layer is determined from the positions of the light spots.

  • Patent number: 7413272
    Abstract: The present invention provides methods and apparatus for controlling the quantity of fluid output (e.g., drop size) by individual nozzles of a print head to a very high precision at a frequency equal to the frequency at which fluid is normally dispensed.

In at least one embodiment, the pixel data includes pixels represented by N bits, and the N bits may represent a drop size for the pixel and a union of the N bits may represent a nozzle status. A print head may be controlled based on the pixel data, and the print head may include nozzles that are each adapted to deposit at least one drop size quantity of a fluid on a substrate.

  • Patent number: 7413627
    Abstract: An improved deposition chamber (2) includes a housing (4) defining a chamber (18) which houses a substrate support (14). A mixture of oxygen and SiF4 is delivered through a set of first nozzles (34) and silane is delivered through a set of second nozzles (34a) into the chamber around the periphery (40) of the substrate support. Silane (or a mixture of silane and SiF4) and oxygen are separately injected into the chamber generally centrally above the substrate from orifices (64, 76). The uniform dispersal of the gases coupled with the use of optimal flow rates for each gas results in uniformly low (under 3.4) dielectric constant across the film.

  • Publication number: 20080190765
    Abstract: The invention relates to a magnetron with a planar target and a planar magnet system. The planar magnet system comprises a bar-shaped first magnet pole with enlarged ends and a frame-shaped second magnet pole, wherein a relative movement between the magnet poles and the target is such that every point of the magnet system moving with the target being stationary moves on a circular path. If the magnet system is stationary, each point of the target moves on such a circular path. During the relative movement with respect to one another the magnet system and the target are in parallel planes. The diameter of the circular path corresponds to the mean distance between two parallel arms of a plasma tube, which during the sputter operation develops between the first and the second magnet pole. Thereby that the magnets in the curve region of the plasma tube are disposed such that the pole lines form at this site a circle arc or a circular area, holes in the target are avoided.

The etching may be done with argon ions, preferably inductively excited by an RF coil around the chamber, or by copper ions, which may be formed with high target power and intense magnetron or by use of the RF coil. Two or more cycles of deposition/etch may be performed. A final flash deposition may be performed with high copper ionization and low wafer biasing.

  • Patent number: 7410737
    Abstract: A method to extend the process monitoring capabilities of a semiconductor wafer optical inspection system so as to be able to detect low-resolution effects of process variations over the surface of a wafer at much higher sensitivity than heretofore possible. The method consists, in essence, of grouping sensed pixels by geometric blocks over the inspected surface and comparing each block with a corresponding one from another die on the same wager, from another wager of from a stored model image. In one embodiment of the invention, pixel values are compared directly and differences are thresholded at a considerably lower level than during a defects detection process. In another embodiment, there is calculated a signature for each block, based on the sensed light intensity values, and corresponding signatures are compared.
