Spin coating device and method
A spin coating device and method. The spin coating device includes a rotatable rotary shaft and sucker fixed on an end portion of the shaft, and an electromagnetic induction device below the sucker which includes an annular magnet fixed below the sucker, coil group formed by a first and second coil, and strip-shaped magnet fixed at the rotary shaft. A base on the sucker has a notch. The unbalanced centrifugal force during rotation of the sucker causes vibration. The electromagnetic induction device enables the centrifugal force generated during rotation of the sucker to be in balance with the magnetic force generated by the electromagnetic induction device to adjust the levelness of the sucker surface. The device does not need manual manipulation, enables the sucker to be more stable, reduces damage to the equipment due to vibration, and improves the effect of photoresist spin-coating while saving time and labor.

Metal spring anchor for advanced packaging
An Fan-out packaging system, comprising dedicated frame with associated movable metallic spring feature(s) for incoming known-good-die (KGD), is invented. The movable spring anchor(s) along with the boundaries of the frame locks the KGD in its designated position during EMC implementation and subsequent processes. In this system/approach, the position accuracy of KGDs during the wafer reconstitution process will be mostly dominated by the dicing accuracy. The proposed system is a very low cost approach as it does not need the expensive software/tool set and does not have a low throughput site-to-site lithography correction during exposure after metrology is carried out for every flash field. This system is particularly useful for chiplet consisting of component chips from different technologies and from substrate made of different material. The frames can be further used as part of function component for the packaged system either as electromagnetic shield, or heat dissipation/heat sink, or even RF antenna as well as other passive devices or active components.
