  • Patent number: 10889097
    Abstract: The present disclosure relates to a debonding apparatus. In some embodiments, the debonding apparatus comprises a wafer chuck configured to hold a pair of bonded substrates on a chuck top surface. The debonding apparatus further comprises a pair of separating blades including a first separating blade and a second separating blade placed at edges of the pair of bonded substrates. The first separating blade has a first thickness that is smaller than a second thickness of the second separating blade. The debonding apparatus further comprises a flex wafer assembly configured to pull the pair of bonded substrates upwardly to separate a second substrate from a first substrate of the pair of bonded substrate. By providing unbalanced initial torques on opposite sides of the bonded substrate pair, edge defects and wafer breakage are reduced.

  • Publication number: 20200085073
    Abstract: Food products and systems and methods for their production involve microfiltration (“MF”) of fluid skim to form a MF retentate, combining the MF retentate with cream and subjecting the combination to ultrafiltration (“UF”) to form a UF retentate. Prior to UF, the composition is formed of non-acidified components. Following UF, the UF retentate is acidified and forms a food product including a high solids content. The solids content may be further increased using evaporation. The resulting cheese or cheese base contains a lower whey protein ratio in a fat:casein:whey protein ratio compared to systems and methods that do not employ MF.

  • Patent number: 10155369
    Abstract: The present disclosure relates to a method for debonding a pair of bonded substrates. In the method, a debonding apparatus is provided comprising a wafer chuck, a flex wafer assembly, and a set of separating blades. The pair of bonded substrates is placed upon the wafer chuck so that a first substrate of the bonded substrate pair is in contact with a chuck top surface. The flex wafer assembly is placed above the bonded substrate pair so that its first surface is in contact with an upper surface of a second substrate of the bonded substrate pair. A pair of separating blades having different thicknesses is inserted between the first and second substrates from edges of the pair of bonded substrates diametrically opposite to each other while the second substrate is concurrently pulled upward until the flex wafer assembly flexes the second substrate from the first substrate. By providing unbalanced initial torques on opposite sides of the bonded substrate pair, edge defects and wafer breakage are reduced.

  • Patent number: 10104731
    Abstract: A dimmable driver for an LED light fixture allows multiple types of dimmers to be used with the light fixture. The dimmable driver may be disconnected from one type of dimmer and subsequently connected to another type of dimmer without having to replace or otherwise adjust the driver for each dimmer. Multiple types of dimmers may be connected to dimmable driver at the same time and the dimmable driver may use dimming signals from one or several of these dimmers. In some embodiments, the dimmable driver is configured to accommodate a step dimmer, a 0-10 V dimmer, and a phase-cut dimmer. Other dimmers and dimming protocols may be accommodated by the dimmable driver in alternative embodiments. Such an arrangement maximizes flexibility for lighting specifiers, contractors, and distributors while minimizing potential errors, costs, delays, and obsolete inventory.
