Latest Patents
One of his latest patents is a bonding system and inspection method for inspecting combined substrates. This innovative bonding system includes a bonding device, an inspection device, and a controller. The bonding device is responsible for forming a combined substrate by bonding a first substrate and a second substrate together. The inspection device then inspects the combined substrate to ensure quality and precision. The controller plays a vital role in managing the inspection process, featuring a measurement controller, a comparison unit, and a re-measurement controller. The measurement controller directs the inspection device to measure the combined substrate at a specified number of measurement points. The comparison unit evaluates the inspection results, particularly focusing on the deviation between the two substrates. If necessary, the re-measurement controller prompts the inspection device to conduct further measurements at additional points to ensure accuracy.
Another notable patent involves a bonding system that consists of a first holder and a second holder, which are positioned apart in a vertical direction. This system includes a position adjuster that allows for horizontal adjustments between the two substrates. A pressing unit is utilized to bond the substrates together, while a measuring unit assesses any position deviations between alignment marks on both substrates. The position adjustment controller ensures that the bonding process is optimized based on previous measurements.
