  • Publication number: 20160023436
    Abstract: The invention broadly relates to release layer compositions that enable thin wafer handling during microelectronics manufacturing. Preferred release layers are formed from compositions comprising a polyamic acid or polyimide dissolved or dispersed in a solvent system, followed by curing and/or solvent removal at about 250° C. to about 350° C. for less than about 10 minutes, yielding a thin film. This process forms the release compositions into polyimide release layers that can be used in temporary bonding processes, and laser debonded after the desired processing has been carried out.

  • Patent number: 9224631
    Abstract: Multiple bonding layer schemes that temporarily join semiconductor substrates are provided. In the inventive bonding scheme, at least one of the layers is directly in contact with the semiconductor substrate and at least two layers within the scheme are in direct contact with one another. The present invention provides several processing options as the different layers within the multilayer structure perform specific functions. More importantly, it will improve performance of the thin-wafer handling solution by providing higher thermal stability, greater compatibility with harsh backside processing steps, protection of bumps on the front side of the wafer by encapsulation, lower stress in the debonding step, and fewer defects on the front side.

  • Patent number: 9203896
    Abstract: The present invention discloses a method and an apparatus for data interaction, and the method includes: obtaining required times of data interaction between valid applications in a background application mode and a network; selecting a minimum required time from the current required times as a target required time of data interaction, and starting timing; when the target required time expires, obtaining each valid application whose current required time of data interaction is between two consecutive target required times, and determining the valid application as a target application; and activating a packet data protocol PDP, establishing a data link between the target application and the network, and performing data interaction, and then restarting timing.

  • Patent number: 9125303
    Abstract: One embodiment of a power supply input routing apparatus can include a multilayer printed circuit board configured to accept only an alternating current (AC) line voltage, return and ground signals. The AC power jumper board can advantageously route AC power from one section of the power supply to another without burdening the power supply design with extra layer requirements or negatively increasing power supply area. Embodiments including an electronic device having a power supply as above are also disclosed.

  • Patent number: 9117757
    Abstract: Novel compositions and methods of using those compositions to form high refractive index coatings are provided. The compositions comprise a mixture of two silicone polymers, a catalyst, and an inhibitor for the catalyst. The preferred catalyst comprises platinum. Unlike prior art silicone systems, the inventive composition can be provided in a one-part form due to a substantially improved pot life. The compositions can be spin- or spray-applied, followed by baking to crosslink the polymers and form a cured layer. The inventive cured layers have high refractive indices and light transmissions.

  • Publication number: 20150106638
    Abstract: The embodiments discussed herein relate to systems, methods, and apparatus for controlling power consumption of a computing device in a standby or sleep mode. During the standby or sleep mode an external device can be plugged into the computing device. The external device can be provided power from a standby power supply until a determination is made as to whether a main power supply is operating. The determination can be based on comparing the output of the main power supply to an output of the standby power supply. If the main power supply is operating, a switch in the computing device can close to allow the main power supply to provide power to the external device. Moreover, in some embodiments, the switch can close based exclusively on a current demand of the external device from the standby power supply.

  • Patent number: 8940104
    Abstract: A cleaning composition for removing temporary wafer bonding material is provided. The cleaning composition comprises an alkylarylsulfonic acid and an aliphatic alcohol dispersed or dissolved in a hydrocarbon solvent system. Methods of separating bonded substrates and cleaning debonded substrates using the cleaning composition are also provided. The invention is particularly useful for temporary bonding materials and adhesives. The methods generally comprise contacting the bonding material with the cleaning solution for time periods sufficient to dissolve the desired amount of bonding material for separation and/or cleaning of the substrates.
