Abstract: There is provided a system and method of assisting defect detection on a semiconductor specimen. The method includes obtaining a first map informative of multiple care areas (CAs) to be inspected on a die; creating a plurality of bounding rectangles (BRs) enclosing the multiple CAs; and compacting the plurality of BRs to a set of compacted rectangles to meet a predefined inspection capacity while attempting to minimize a non-CA area enclosed by the set of compacted rectangles, giving rise to a second map informative of the set of compacted rectangles. The compaction comprises constructing an R-tree structure representative of the plurality of BRs and compacted rectangles, and selecting a set of nodes from the R-tree structure based on the predefined inspection capacity and representative of the set of compacted rectangles. The second map is usable for filtering a defect map indicative of defect candidate distribution on the die.

Abstract: Magnetic memory cells, methods of fabrication, semiconductor device structures, and memory systems are disclosed. A magnetic cell core includes at least one magnetic region (e.g., a free region or a fixed region) configured to exhibit a vertical magnetic orientation, at least one oxide-based region, which may be a tunnel junction region or an oxide capping region, and at least one magnetic interface region, which may comprise or consist of iron (Fe). In some embodiments, the magnetic interface region is spaced from at least one oxide-based region by a magnetic region. The presence of the magnetic interface region enhances the perpendicular magnetic anisotropy (PMA) strength of the magnetic cell core. In some embodiments, the PMA strength may be enhanced more than 50% compared to that of the same magnetic cell core structure lacking the magnetic interface region.
