Latest Patents

Rathore's latest patents include two notable inventions. The first patent focuses on an evaluation system designed to assess a hole formed in an intermediate product. This system incorporates an imager and a processing circuit. The imager is configured to capture an electron image of a hole created by an etch process, which exposes at least one layer of a set of layers that differ by their electron yield. The processing circuit evaluates whether the hole reaches a target layer of the intermediate product, which is essential in the manufacturing process of three-dimensional NAND memory units. The hole exhibits a high aspect ratio and has a width on a nanometric scale.

The second patent presents a technique for measuring overlay between layers of a multilayer structure. This method involves obtaining an image representing the multilayer structure and expected images for its layers. By combining these expected images, the method performs registration and segmentation of the given image, producing segmented images and maps of the layers. This process allows for the determination of overlay between any two selected layers by analyzing the maps alongside the expected images.
