Latest Patents

Hang Ran holds a patent for a "Spin Coating Device and Method." This invention features a spin coating device that includes a rotatable rotary shaft and a sucker fixed on one end of the shaft. The device is equipped with an electromagnetic induction device located below the sucker, which consists of an annular magnet, a coil group formed by a first and second coil, and a strip-shaped magnet fixed at the rotary shaft. The design incorporates a base on the sucker with a notch, allowing for improved stability during operation. The unbalanced centrifugal force generated during the rotation of the sucker causes vibration, which the electromagnetic induction device counteracts. This innovation allows for a balanced centrifugal force and magnetic force, enhancing the levelness of the sucker surface. The device minimizes manual manipulation, increases stability, reduces equipment damage from vibration, and improves the photoresist spin-coating effect while saving time and labor.
