    摘要: Processing for a silicon photonics wafer is provided. A silicon photonics wafer that includes an active silicon photonics layer, a thin buried oxide layer, and a silicon substrate is received. The thin buried oxide layer is located between the active silicon photonics layer and the silicon substrate. An electrical CMOS wafer that includes an active electrical layer is also received. The active silicon photonics layer of the silicon photonics wafer is flip chip bonded to the active electrical layer of the electrical CMOS wafer. The silicon substrate is removed exposing a backside surface of the thin buried oxide layer. A low-optical refractive index backing wafer is added to the exposed backside surface of the thin buried oxide layer. The low-optical refractive index backing wafer is a glass substrate or silicon substrate wafer. The silicon substrate wafer includes a thick oxide layer that is attached to the thin buried oxide layer.

    摘要: A bright-field, particle position determining optical system is disclosed that uses both phase shift and extinction signals to determine particle trajectories. In a first embodiment, a pair of orthogonally polarized beams are positioned along an axis that intersects a particle's flow path at an acute angle. An optical system recombines the beams after they exit the flow path, the combined beams manifesting an elliptical polarization if a particle intersects one of the beams. Bright field detectors detect polarization components of the combined beam, provide a phase shift signal between the beam's orthogonal components and provide corresponding signals to a processor. The processor determines a signal asymmetry from the phase shift signal that is indicative of a particle's position in the flow path. Another embodiment of the invention examines a signal resulting from the beam's phase shift and determines a correction factor that is dependent upon the distance of the particle from the focal plane of the beams. Another embodiment employs a dithering system for cyclically moving one or more optical beams across a particle to further enable its trajectory or position to be determined.

    摘要: A method and structure for controlling a manufacturing tool includes measuring different manufacturing parameters of the tool, transforming a plurality of time series of the manufacturing parameters into intermediate variables based on restrictions and historical reference statistics, generating a surrogate variable based on the intermediate variables, if the surrogate variable exceeds a predetermined limit, identifying a first intermediate variable, of the intermediate variables, that caused the surrogate variable to exceed the predetermined limit and identifying a first manufacturing parameter associated with the first intermediate variable, and inhibiting further operation of the tool until the first manufacturing parameter has been modified to bring the surrogate value within the predetermined limit.

    摘要: An optical inspection system for patterned semiconductor wafers generates a dark field image of the wafer by applying a collimated beam of monochrome light at an incident angle with respect to the surface of the wafer of between 8.degree. and a maximum angle defined by the numerical aperture of the imaging system and collecting the light which is scattered at angles approximately normal to the surface of the wafer and within the numerical aperture of the imaging system. In addition, the incident light is at an angle of 45.degree. in the surface plane of the wafer with respect to the rectangular lines which predominate in the pattern. Before forming the dark field image, the collected light is passed through a Fourier transform filter which substantially attenuates spatial frequency components corresponding to the pattern. In the resultant dark field image, defects in the pattern and contaminating particles are accentuated relative to the pattern features.
