    摘要: Transfer methods disclosed herein include transferring micro-LEDs from a first carrier to a second carrier. The methods include bonding the micro-LEDs to the first carrier using a first releasable bonding layer that releases when exposed to actinic light. The micro-LEDs are then secured to a second carrier. The first bonding layer is then irradiated through the first releasable bonding layer through the first carrier with the actinic light to release the micro- LEDs from the first carrier. The second carrier can be a display backplane having bonding pads and the micro-LEDs can be secured to the bonding pads. The actinic light can be provided in the form of a scanning actinic light beam. The display backplane can be used to form a micro-LED display. Methods disclosed herein can be used to transfer other devices, such as non-LED light-emitting devices, sensing devices, and microelectromechanical devices, from a first carrier to a second carrier.

    摘要: Method and apparatus for processing a substrate (44) with an energetic particle beam (42). Features (66) on the substrate (44) are oriented relative to the energetic particle beam (42) and the substrate is scanned through the energetic particle beam (42). The substrate is periodically indexed about its azimuthal axis of symmetry (122), while shielded from exposure to the energetic particle beam (42), to reorient the features relative to the major dimension of the beam. When the substrate is shielded, the energetic particle particle beam is turned off.

    摘要: Apparatuses for reducing radiation thermometry bias errors in enclosures such as CVD reactors. In one embodiment, a radiation thermometer utilizes an off-focus telecentric lens arrangement. The off-focus telecentric arrangement is focused at infinity, but is utilized to capture radiation from a relatively proximate target (e.g., within a couple meters) that is out of focus. The capture of collimated radiation from the target diminishes the contribution of stray radiation. In another embodiment, scattered radiation originating from a designated segment of a peripheral heating element can be reduced locally by one of several mechanisms, including reducing the emission (e.g., operating temperature) of the designated segment, or capturing or deflecting a portion of the radiation originating from the designated segment. Radiation thermometers fixed proximate an axis that extends from the center of the wafer carrier and across the designated segment are subject to less stray radiation, thus providing a more reliable temperature reading.

    摘要: A method of in-situ pyrometer calibration for a wafer treatment reactor such as a CVD reactor 12 desirably includes the steps of positioning a calibrating pyrometer 80 at a first calibrating position A and heating the reactor until the reactor reaches a pyrometer calibration temperature. The method desirably further includes rotating a support element 40 about a rotational axis 42, and while the support element is rotating about the rotational axis, obtaining first operating temperature measurements from a first operating pyrometer 71 installed at a first operating position 1R, and obtaining first calibrating temperature measurements from the calibrating pyrometer 80. Both the calibrating pyrometer 80 and the first operating pyrometer 71 desirably are adapted to receive radiation from a first portion of the wafer support element 40 at a first radial distance D1 from the rotational axis 42 of the wafer support element.
