Latest Patents

One of his latest patents is a method of fabricating a flip chip semiconductor device utilizing a polymer layer to reduce thermal expansion coefficient differential. This improved flip chip assembly allows for a semiconductor chip with a specific thermal expansion coefficient to be directly mounted on a circuit substrate with a different thermal expansion coefficient. By incorporating a base layer made of polymer material, the effective thermal expansion coefficient of the solder bumps is modified to better match that of the substrate, thereby minimizing thermal expansion issues at the junction.

Another significant patent is related to an optical grating fabrication process. This process employs real-time measurement of grating characteristics, such as grating period chirp and reflectivity, as feedback to enhance the writing process. By launching a test beam through the optical medium during the writing process, Deshmukh can measure specific characteristics and generate a corrective apodization refractive index profile. This closed-loop approach allows for the creation of gratings with finely tuned characteristics, improving their overall performance.
