Latest Patents

One of his latest inventions, a **seamless, maskless lithography system using spatial light modulator**, revolutionizes traditional lithography by removing the need for masks. It employs a programmable Spatial Light Modulator (SLM) equipped with high parallel processing capabilities. By illuminating the SLM with a radiation source—preferably a pulsed laser or a shuttered lamp—this invention creates a patterning image projected onto a substrate. The use of a Deformable Micromirror Device (DMD) allows for reflective pixel selection, while alternative options like a Liquid Crystal Light Valve (LCLV) enable pass-through pixel selection. The system enhances efficiency through error correction, pixel selection control, and seamless scanning, making it suitable for rapid prototyping and flexible manufacturing.

Another notable patent from Hoffman is the **zoom illumination system for use in photolithography**, which allows for dynamic control over the size of the illumination field incident to a scattering optical element. This system includes various optical components, such as an optical source, beam conditioner, and zoom array integrator (ZAI), ensuring telecentric illumination is maintained throughout the zoom range. This innovation optimizes the photolithographic process, improving imaging fidelity and manufacturing efficiency.
