CLAMPING SYSTEMS AND METHODS FOR SEMICONDUCTOR PROCESSING
A new clamping system is described. The system comprises an electrode configured to generate an electric field to provide a clamping force, and a capping layer coupled to the electrode. The capping layer is configured to reduce a local maximum in the electric field strength, located at or near the edge of the electrode. The capping layer causes a redistribution of electric field lines around the edge of the electrode, as material of the capping layer is configured to store more electric energy, which locally reduces the electric field strength. This local reduction in electric field strength reduces or prevents "hot spots" in a clamp, which facilitates increased clamping pressure, reduces the risk of clamp failure, reduces or prevents residual clamp holding forces, and has other advantages.

INTEGRATED OPTICS DISTANCE, LEVELING AND TILT SENSOR
The present system(s) and method(s) use an integrated photonic sensor to determine tilt angle present at the metrology region or mark. The integrated photonic sensor uses two pairs of grating couplers, each pair having an emitting grating coupler and a capturing grating coupler. The positions of the grating couplers may be fixed where a first capturing grating coupler will capture a peak captured light value of its paired emitting grating coupler when the angle of tilt at the region is a positive angle, and a second capturing grating coupler will capture a peak captured light value of its paired emitting grating coupler when the angle of tilt at the region is a negative angle. Using this fixed configuration and knowing the tilt angles at which peak coupling efficiencies would be captured, a ratio is computed using the two captured light values. A tilt angle is determined using this ratio.

A system and method for determining a position of one or more semiconductor donor dies relative to one or more carrier marks on a carrier of the one or more semiconductor donor dies; and aligning the one or more semiconductor donor dies to one or more corresponding acceptor locations, referenced to the one or more carrier marks, for bonding, based on the position.
Existing die-to-wafer bonding tools use guided alignment to position the dies. A donor die position and its bonding location on an acceptor wafer are measured, and used as input for a bonding transfer mechanism. The measurements and the transfer mechanism contribute to placement errors. Die-to-wafer bonding accuracy requirements are increasing, with placement accuracy down to 50 nm and below often required. Achieving this accuracy with existing die-to-wafer bonding tools is challenging. As a result, new systems and methods for die bonding self-alignment have been developed. As with guided alignment, a transfer mechanism moves the donor die in proximity to a desired acceptor location on an acceptor wafer, but then a self-alignment mechanism controls a relative position between the die and the acceptor wafer during the bonding. This enhances bonding placement accuracy compared to existing die-to-wafer bonding tools, among other advantages.

Systems and methods for providing variable spot size and variable focus at a substrate are described. Sets of variable focal length lenses can be added to an alignment system to allow for adjustment of the spot size and focus. A variable focal length lens is a liquid lens that is tunable based on application of voltage across the lens. Toggling the voltage changes the water-oil interface in the liquid lens, which in turn changes the direction of light passing through. For example, turning on the voltage across the lens shifts the light output direction to converging at a focal point. As a result, variable focal length lenses provide adjustment to compensate for the fixed spot size and focus shortcomings of the prior art. Furthermore, variable focal length lenses can also be applied to compensate for spot shift and higher order diffraction orders.

VIBRATION CORRECTION FOR INTERFEROMETRIC OR HOLOGRAPHIC METROLOGY
Interferometric or holographic metrology systems may be used to determine overlay, alignment, and/or other metrics. Light scattered into different diffraction orders is detected by a first radiation sensor, together with two reference beams. The reference beams are carefully matched to two illumination paths from the two sources, such that a total interference pattern forms a hologram that encodes measurement information. Computational processing of the hologram determines metrology values. However, vibrations from metrology system stage settling and/or other sources cause path length shifts in the diffracted radiation. This negatively affects sensor performance. Advantageously, a second radiation sensor having a relatively higher frame rate is used to measure a phase shift from vibrations in near-real-time and make corrections for the vibrations.
