Embodiments of the invention generally relate to apparatuses for chemical vapor deposition (CVD) processes. In one embodiment, a heating lamp assembly for a vapor deposition reactor system is provided which includes a lamp housing disposed on an upper surface of a support base and containing a first lamp holder and a second lamp holder and a plurality of lamps extending from the first lamp holder to the second lamp holder. The plurality of lamps may have split filament lamps and/or non-split filament lamps, and in some examples, split and non-split filament may be alternately disposed between the first and second lamp holders. A reflector may be disposed on the upper surface of the support base between the first and second lamp holders. The reflector may contain gold or a gold alloy.

A system and method for displaying aircraft glide slope includes determining a glide slope deviation that is representative of a difference between a desired aircraft glide slope and an actual aircraft glide slope. A glide slope icon that is representative of the desired aircraft glide slope and a glide slope deviation icon that is representative of the determined glide slope deviation are simultaneously rendered on a display.

Embodiments of the invention generally relate to apparatuses and methods for producing epitaxial thin films and devices by epitaxial lift off (ELO) processes. In one embodiment, a method for forming thin film devices during an ELO process is provided which includes coupling a plurality of substrates to an elongated support tape, wherein each substrate contains an epitaxial film disposed over a sacrificial layer disposed over a wafer, exposing the substrates to an etchant during an etching process while moving the elongated support tape, and etching the sacrificial layers and peeling the epitaxial films from the wafers while moving the elongated support tape. Embodiments also include several apparatuses, continuous-type as well as a batch-type apparatuses, for forming the epitaxial thin films and devices, including an apparatus for removing the support tape and epitaxial films from the wafers on which the epitaxial films were grown.

Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. A photovoltaic (PV) device may incorporate front side and/or back side light trapping techniques in an effort to absorb as many of the photons incident on the front side of the PV device as possible in the absorber layer. The light trapping techniques may include a front side antireflective coating, multiple window layers, roughening or texturing on the front and/or the back sides, a back side diffuser for scattering the light, and/or a back side reflector for redirecting the light into the interior of the PV device. With such light trapping techniques, more light may be absorbed by the absorber layer for a given amount of incident light, thereby increasing the efficiency of the PV device.

Embodiments of the invention generally relate to a method for forming a multi-layered material during a continuous chemical vapor deposition (CVD) process. In one embodiment, a method for forming a multi-layered material during a continuous CVD process is provided which includes continuously advancing a plurality of wafers through a deposition system having at least four deposition zones. Multiple layers of materials are deposited on each wafer, such that one layer is deposited at each deposition zone. The methods provide advancing each wafer through each deposition zone while depositing a first layer from the first deposition zone, a second layer from the second deposition zone, a third layer from the third deposition zone, and a fourth layer from the fourth deposition zone. Embodiments described herein may be utilized to form an assortment of materials on wafers or substrates, especially for forming Group III/V materials on GaAs wafers.

A method of dynamically displaying lateral deviation in formats on a display is provided. The method comprises assigning one or more positional boundaries for displaying the lateral deviation information, wherein the one or more positional boundaries define areas on a display. The method also comprises calculating display positions of a lateral deviation symbology and determining if each calculated display position is allowed based on where the lateral deviation display would be located, if displayed at each calculated position, in relation to the one or more positional boundaries. The method further comprises, displaying the lateral deviation symbology at the calculated positions when the calculated positions are allowed, and displaying a lateral deviation indicator when the calculated positions are not allowed.

To manage data flow in generating profile models for use in optical metrology, a project data object is created. A first profile model data object is created. The first profile model data object corresponds to a first profile model defined using profile parameters. A version number is associated with the first profile model data object. The first profile model data object is linked with the project data object. At least a second profile model data object is created. The second profile model data object corresponds to a second profile model defined using profile parameters. The first and second profile models are different. Another version number is associated with the second profile model data object. The second profile model data object is linked with the project data object. The project data object, the first profile model data object, and the second profile model data object are stored. The version numbers associated with the first profile model data object and the second profile model data object are stored. The link between the first profile model data object and the project data object is stored. The link between the second profile model data object and the project data object is stored.

Methods and apparatus are provided for displaying terrain and attitude data symbology for an aircraft. The apparatus is a hybrid centered head-down display for an aircraft having a monitor configured to generate a display and a processor coupled to the display. The display has a centerline. The processor is configured to calculate a displayed drift angle limit, a displayed drift angle, align the centerline of the display with reference to the displayed drift angle, and generate on the display a first symbol corresponding to a terrain and a second symbol corresponding to an attitude of the aircraft. The processor is further configured to center the first symbol and the second symbol with reference to the centerline.
