Title: Innovations of Madhumita Sengupta
Introduction
Madhumita Sengupta is an accomplished inventor based in Sunnyvale, California. She has made significant contributions to the field of imaging and charged particle beam systems. With a total of three patents to her name, her work showcases her expertise and innovative spirit.
Latest Patents
One of her latest patents is focused on the sub-resolution alignment of images. This invention involves aligning a plurality of images, including a first image and a second image with a higher resolution than the first. The process generates an oversampled cross-correlation image that corresponds to the relative displacements of the images. By determining an offset value based on this image, the alignment is achieved with precision greater than the resolution of the first image. Enhanced results are obtained through additional iterations of this process.
Another notable patent by Sengupta is related to enhanced scanning control of charged particle beam systems. This invention includes a charged particle beam system capable of imaging and possibly editing a device under test (DUT). The system features a charged particle beam generation unit, such as a focused ion beam (FIB) column, which emits a charged particle beam onto the DUT. The scanning control method utilizes a finite state machine to manage the application of the charged particle beam according to various scanning control parameters.
