With a total of 4 patents to his name, Heo is recognized for his advancements in maskless exposure methods.

Latest Patents

His latest patents include a maskless exposure method and a maskless exposure device designed for performing this exposure method. The maskless exposure device features a stage on which a substrate is placed, an optical head, and an optical source part. The optical head is responsible for irradiating light onto the substrate, while the light source part supplies the optical head with the necessary light. The device operates by adjusting the light according to an average-focus distance, which is calculated by averaging the best-focus distances across multiple regions of the substrate.

Another notable patent involves a maskless exposure device that includes an exposure head equipped with a digital micro-mirror device and an exposure source. This innovative design allows the digital micro-mirror device to reflect a source beam from the exposure source onto the substrate. The system controller manages the digital micro-mirror device using a graphic data system file that contains data about the patterns to be formed on the substrate. This patent also describes a pattern that extends parallel to the scan direction of the exposure head, featuring alternating portions of varying widths.
