Abstract: A lift-off method for transferring an optical device layer in an optical device wafer to a transfer substrate, the optical device layer being formed on the front side of an epitaxy substrate through a buffer layer. A transfer substrate is bonded through a bonding layer to the front side of the optical device layer of the optical device wafer, thereby forming a composite substrate. A pulsed laser beam having a wavelength transmissive to the epitaxy substrate and absorptive to the buffer layer is applied from the back side of the epitaxy substrate to the buffer layer, thereby breaking the buffer layer, and the epitaxy substrate is peeled from the optical device layer, thereby transferring the optical device layer to the transfer substrate. Ultrasonic vibration is applied to the composite substrate in transferring the optical device layer.

Abstract: The present technology discloses a system, for joining workpieces using energy, such as ultrasonic energy, where the energy concentrates at a location within a weld area, promoting sequential melting of a plurality of energy directors. The system can be configured so that the sequential melting begins at the center of the weld area and progresses outwards. Sequential melting may occur through use of a welding tip configured to reduce air pockets, a tapering the height of a plurality of energy directors, and/or tapering the energy directors themselves, all of which reduce the size of an energy transfer area produced by thermal energy. The present technology also includes a method for joining workpieces using energy such as ultrasonic energy that concentrates at a location within a weld area causing sequential melting of a plurality of energy directors using the aforementioned features.

Abstract: A sonotrode and anvil are adapted for ultrasonic welding of work pieces, to produce a narrower weld region that exhibits greater durability, permitting use of less material per package. The horn-to-anvil contact is through a plurality of energy directors arranged into a three-dimensional grid pattern to be capable of distributed vibration-transmissive contact. The energy directors include a series of plateau surfaces regularly spaced apart in a first direction, and in a second direction that is orthogonal to the first direction, to form the grid pattern. The energy directors of the horn are configured to interlock with the energy directors of the anvil. The rectangular-shaped plateaus are spaced apart by angled side-surfaces that form valleys. A stepped transition to a corresponding region of reduced height for the energy directors of the sonotrode and anvil may form a cosmetic seal region with a lesser integrity, in addition to the main barrier seal.

Abstract: Advanced ultrasonic welding components of co-pending application Ser. No. 12/925,652 are readily incorporated into new form-fill-seal machines, but owners of existing machines utilizing heat-seal stations were unsuccessful at swapping the sealing packages. Retrofit kits to a replace heat sealing station with an advanced ultrasonic sonotrode and anvil comprise: a housing; a linear rail fixed thereto; first and second bearing carriages being slidable upon the rail; and first and second fluidic muscles. Each of the fluidic muscles is mounted with a first end fixed to a respective housing wall, and a second end fixed to a respective bearing carriage, permitting actuation of each carriage through pressurization and depressurization of the muscles. The advanced anvil and sonotrode may be secured to respective carriages.
