摘要:
Epitaxial formation support structures and associated methods of manufacturing epitaxial formation support structures and solid state lighting devices are disclosed herein. In several embodiments, a method of manufacturing an epitaxial formation support substrate can include forming an uncured support substrate that has a first side, a second side opposite the first side, and coefficient of thermal expansion substantially similar to N-type gallium nitride. The method can further include positioning the first side of the uncured support substrate on a first surface of a first reference plate and positioning a second surface of a second reference plate on the second side to form a stack. The first and second surfaces can include uniformly flat portions. The method can also include firing the stack to sinter the uncured support substrate. At least side of the support substrate can form a planar surface that is substantially uniformly flat.
摘要:
Releasable semiconductor dice are deposited with a magnetic layer and held by magnetic forces to a magnetic or electromagnetic transfer stamp for the transfer of the dice from a host substrate directly or indirectly to a target substrate.
摘要:
A transfer-enabling apparatus, produced by a method of manufacturing, includes a substrate patterned with islands separated by trenches and an epitaxial layer, grown at least on the islands, providing semiconductor dice in such a configuration partially released from said substrate and suspended over the substrate, and interconnected, by anchors of epitaxial or other material that are attached to the substrate. The anchors are of width less than or equal to than the semiconductor dice and define fracture zones at connections of the anchors with the semiconductor dice.
