Introduction

Douglas Joseph Van Den Broeke is an accomplished inventor based in Sunnyvale, CA. He has made significant contributions to the field of lithography, holding 2 patents that showcase his innovative approach to technology.

Latest Patents

His latest patents include a "Mura Reduction Method," which presents a system, methods, and a non-transitory computer-readable medium for digital lithography aimed at reducing mura in substrate sections. This invention ensures that the boundary lines of the digital lithography remain invisible. The system comprises a processing unit that prints a virtual mask file provided by a controller, which receives data and converts it into a virtual mask file with an exposure pattern for the lithographic process. The exposure pattern consists of multiple sections that interact seamlessly to create an invisible boundary.

Another notable patent is the "Universal Metrology File, Protocol, and Process for Maskless Lithography Systems." This invention relates to a system, software application, and method that updates various parameters within a lithography environment. The file utilized in this process is readable by all components, facilitating communication and ensuring that the mask pattern corresponds accurately to the intended design. This innovation enhances the calibration of maskless lithography devices and corrects process parameters for precise writing on substrates.
