A highly productive and user-friendly aligner, such as a microscope auto-move.
This is a manual exposure device compatible with 2-inch wafers. It is an exposure device where the operator manually sets the wafer. Using a 4-inch glass mask, the alignment marks of the photomask and the wafer are captured with a microscope, and alignment is performed while viewing the images displayed on the monitor, along with setting the exposure gap, allowing for exposure to take place. Additionally, when the exposure switch is pressed, the microscope automatically retracts, the lamp house moves to the designated position, and the exposure is carried out with the set light intensity, followed by automatic retraction.

basic information
Main Features 1. The parallel alignment of the photomask and wafer employs a method that levitates the wafer table using a layer of air and makes precise contact with the photomask through air springs built into the alignment mechanism. 2. The alignment microscope can move freely to make it easier to locate the alignment marks (with a locking mechanism). 3. The alignment microscope is a zoom-type high-magnification model equipped with LED lighting that allows color selection based on the resist. 4. To enhance work efficiency, the lamp house and alignment microscope automatically insert and retract, thereby improving productivity.
