An electrostatic zipping actuator includes a primary electrode, a secondary electrode overlying the primary electrode, a dielectric layer located between and abutting at least a portion of the primary electrode and the secondary electrode, and a dielectric fluid disposed at least at a junction between the dielectric layer and one of the electrodes, where an average total thickness of the dielectric layer is less than approximately 10 micrometers.

A pick-up head assembly comprises a body of a liquid crystalline elastomer (LCE) that undergoes a reversible expansion when exposed to a first frequency of light and contracts when exposed to a second frequency of light. Selective portions of the LCE in the pick-up head assembly are irradiated with the first frequency to cause an expansion in the selective portions. The adhesive forces of the expanded portions of the LCE are used to pick-up semiconductor devices from a first substrate. The semiconductor devices are placed on a second substrate by exposing the expanded portions of the LCE to the second frequency of light, causing the expanded portions to contract.

The disclosed method of manufacturing may include positioning a membrane on top of a channeled layer where the channeled layer includes a shim portion that is dimensioned to limit the amount of compression appliable to the membrane. The membrane may be positioned at a juncture in the channeled layer. The method may next include positioning a transmission housing layer membrane and the channeled layer. The method may also include fastening the channeled layer, the membrane, and the transmission housing layer together. The channeled layer, the membrane, and the transmission housing layer may be held together with at least one fastening member. Various other methods, systems, and computer-readable media are also disclosed.

Fluidic control: clamped membrane structure

A method and system for assembling a device by picking up semiconductor devices from a carrier substrate and placing the semiconductor devices onto a target substrate. The transfer of the semiconductor devices uses fluid as a transfer medium. The fluid enters a fluid channel of a pickup head, causing the pickup head to expand, make contact with, and attach to an aligned semiconductor device. After the semiconductor device is aligned with and placed onto the target substrate, at least a portion of the fluid is removed from the pickup head to release the semiconductor device onto the target substrate. The semiconductor device bonds to the target substrate.
