摘要： Embodiments of the invention are provided for a thin film stack containing a plurality of epitaxial stacks disposed on a substrate and a method for forming such a thin film stack. In one embodiment, the epitaxial stack contains a first sacrificial layer disposed over the substrate, a first epitaxial film disposed over the first sacrificial layer, a second sacrificial layer disposed over the first epitaxial film, and a second epitaxial film disposed over the second sacrificial layer. The thin film stack may further contain additional epitaxial films disposed over sacrificial layers. Generally, the epitaxial films contain gallium arsenide alloys and the sacrificial layers contain aluminum arsenide alloys. Methods provide the removal of the epitaxial films from the substrate by etching away the sacrificial layers during an epitaxial lift off (ELO) process. The epitaxial films are useful as photovoltaic cells, laser diodes, or other devices or materials.

摘要： Embodiments of the invention generally relate to a chemical vapor deposition system and related method of use. In one embodiment, the system includes a reactor lid assembly having a body, a track assembly having a body and a guide path located along the body, and a heating assembly operable to heat the substrate as the substrate moves along the guide path. The body of the lid assembly and the body of the track assembly are coupled together to form a gap that is configured to receive a substrate. In another embodiment, a method of forming layers on a substrate using the chemical vapor deposition system includes introducing the substrate into a guide path, depositing a first layer on the substrate and depositing a second layer on the substrate, while the substrate moves along the guide path; and preventing mixing of gases between the first deposition step and the second deposition step.

摘要： A method and system for dicing semiconductor devices from semiconductor thin films. A semiconductor film, backed by a metal layer, is bonded by an adhesive layer to a flexible translucent substrate. Reference features define device boundaries. An ultraviolet laser beam is aligned to the reference features and cuts through the semiconductor film, the metal layer and partially into the adhesive layer, cutting a frontside street along a real or imaginary scribe line on the cutting path. An infrared laser beam is aligned to the trough of the frontside street from the back surface of the flexible substrate, or the scribe lines are mapped to the back surface of the flexible substrate. The infrared laser beam cuts through the flexible substrate and the majority of the thickness of the adhesive layer, cutting a backside street along the scribe line. The backside street overlaps or cuts through to the frontside street, thereby separating the semiconductor devices.

摘要： There is provided a method for determining the in-band noise in agile multichannel Dense Wavelength Division Multiplexing (DWDM) optical systems, where the interchannel noise is not representative of the in-band noise in the optical channel. The method relies on the analysis of two observations of the same input optical signal. In the two observations, the linear relationship between the optical signal contribution and the optical noise contribution (i.e. the observed OSNR) is different, which allows the discrimination of the signal and noise contributions in the input optical signal. In a first approach, the two observations are provided by polarization analysis of the input optical signal. In a second, the input optical signal is obtained using two different integration widths.

摘要： Embodiments for displaying first and second images to a pilot of an aircraft are presented. The embodiments include, but are not limited to, obtaining a first image signal and a second image signal, commanding a display unit to display a first image on a display screen corresponding to the first signal, and computing an image moving velocity of the first image. The method further comprises estimating an image flow velocity for the second image based on the second image signal and comparing the image moving velocity of the first image to the image flow velocity of the second image. After the comparison, the display unit is commanded to display the second image overlaid on the first image, and commanding the display unit to establish an intensity of the second image within a predefined range based upon the comparison.
