Title: Naomi Ittah: Innovator in Semiconductor Manufacturing
Introduction
Naomi Ittah is a prominent inventor based in Ramat Gan, Israel. She has made significant contributions to the field of semiconductor manufacturing, holding 2 patents that showcase her innovative approach to technology.
Latest Patents
Her latest patents include a method of overlay control in silicon wafer manufacturing. This method involves locating a target comprising a diffraction grating on a wafer layer and measuring the alignment of patterns in successive layers of the wafer. The target location may be achieved using a pupil camera rather than a vision camera, which scans the target to obtain pupil images at different locations along a first axis. The pupil images contain a first-order diffraction pattern for each location, and a measurement of signal intensity in this pattern is obtained. The variation of signal intensity with location along each axis is analyzed to calculate the location of a feature in the target.
Another notable patent involves three-dimensional mapping of a wafer. This patent provides methods and scatterometry overlay metrology tools that scan a wafer region and perform focus measurements during the scanning process to extract phase information. The depth data derived from this phase information can be used to locate metrology targets and provide material properties concerning wafer layers, thereby estimating process variation and improving overlay measurements.
