Latest Patents
Chang-Woo Woo's latest patents include a wafer aligning apparatus and related methods. The first patent describes a wafer aligning apparatus that features a laser sensor generating a trigger signal. This apparatus includes a CCD camera that images a wafer in response to the trigger signal, a signal processing unit that calculates a center alignment correction value for the wafer, and a robot controller that uses this value to control the movement of a transfer robot. The laser sensor detects changes in reflected light, which helps in aligning the wafer accurately.
The second patent also focuses on a wafer aligning apparatus and method. In this embodiment, the apparatus comprises an imaging unit that captures an image of a wafer being transferred and converts it into digital signals. The signal processing unit then calculates a center alignment correction value by comparing these digital signals to a master image stored within the unit. The robot controller receives this correction value to ensure that the wafer is aligned correctly when it is delivered to a process chamber.
