Title: Innovations of Jonathan Phillip Singer
Introduction
Jonathan Phillip Singer is an accomplished inventor based in Cambridge, MA. He has made significant contributions to the field of lithography, holding 2 patents that showcase his innovative approaches to thin film patterning and complex structure fabrication.
Latest Patents
One of his latest patents is titled "Developer Free Positive Tone Lithography by Thermal Direct Write." This method involves lithographic patterning of thin films, where a thin film is deposited on a substrate and exposed to optical energy from a focused laser. This exposure induces a thermal gradient in the film through optical absorption, allowing the film to soften via a melting or glass transition process. The thermal gradient then induces a directional dewetting, enabling developer-free positive tone lithography and metrology of the thin film based on the morphology of the resultant features.
Another notable patent is the "Hybrid Lithographic Method for Fabricating Complex Multidimensional Structures." This method fabricates intricate structures by depositing a photoresist onto a substrate, which includes a predominantly thermal band of optical absorption. A three-dimensional pattern is generated within the resist using a specific wavelength of light to activate a photoinitiator, producing a latently photostructured resist. Focused laser spike annealing is then applied to accelerate the photoinduced reaction, allowing for three-dimensional direct writing within the resist to define features beyond the interference pattern.
