Latest Patents

One of Kasko's latest patents is titled "Deep alignment marks on edge chips for subsequent alignment of opaque layers." This invention describes a method for forming alignment marks on edge chips within the kerf region of a semiconductor workpiece. The alignment marks are created using a separate lithography mask and can extend into lower layers of the semiconductor device. An opaque material layer is then deposited, and depressions are formed in this layer over the deep alignment mark trenches. These depressions facilitate the alignment of a lithography process, ensuring precision in opening the opaque material layer over the alignment marks in the underlying metallization layer.

Another notable patent is focused on "Methods of patterning a magnetic stack of a magnetic memory cell and structures thereof." In this invention, Kasko outlines a process where the top magnetic material layer of a magnetic stack is patterned using a hard mask. A conformal insulating material is deposited over the patterned layer and hard mask, which is then anisotropically etched to create a sidewall spacer hard mask. This mask is crucial for patterning the remaining material layers of the magnetic stack, potentially remaining in the final magnetic memory cell structure.
