    • A method for fabricating a first memory cell and a second memory cell electrically isolated from each other is provided. A first polysilicon (poly I) layer is formed on an oxide coated substrate. Then, a sacrificial oxide layer and nitride layer are formed for masking the poly I layer. At least a portion of the masking layer is etched to pattern the first memory cell and the second memory cell and an unmasked portion therebetween. The unmasked portion of the poly I layer is transformed into an insulator via thermal oxidation such that the insulator separates a floating gate of the first memory cell from a floating gate of the second memory cell. The insulator is etched so as to form a gap having gradually sloping sidewalls between a floating gate of the first memory cell and a floating gate of the second memory cell, the gap isolating the floating gate of the first memory cell from the floating gate of the second memory cell. Thereafter, an interpoly dielectric layer and a second polysilicon (poly II) layer are formed substantially free of abrupt changes in step height.

    • The present invention relates to wafer alignment. A reticle is employed which includes, a design and first and second alignment marks. The second alignment mark is symmetric to the first alignment mark such that a reticle center point is a midpoint of the first and second alignment marks. The first alignment mark is printed on a surface layer of the wafer. The second alignment mark is printed on the surface layer at an offset from the first alignment mark. A virtual alignment mark is determined, the virtual alignment mark being a midpoint of the printed first and second alignment marks. The virtual alignment mark is employed to facilitate aligning the wafer. The symmetric relationship between the first and second alignment mark results in the negation of print errors of the marks due to reticle rotation and/or lens magnification with respect to the virtual alignment mark. The employment of the virtual alignment mark in wafer alignment substantially facilitates mitigation of overlay error.
    • 本发明涉及晶圆对准。 使用掩模版,其包括设计和第一和第二对准标记。 第二对准标记与第一对准标记对称,使得标线片中心点是第一和第二对准标记的中点。 将第一对准标记印刷在晶片的表面层上。 第二对准标记以与第一对准标记偏移的方式印刷在表面层上。 确定虚拟对准标记,虚拟对准标记是打印的第一和第二对准标记的中点。 采用虚拟对准标记以便于对准晶片。 第一和第二对准标记之间的对称关系导致相对于虚拟对准标记由于标线旋转和/或透镜放大而导致的标记的打印错误的否定。 在晶片对准中使用虚拟对准标记基本上有助于减轻重叠误差。

    • A semiconductor apparatus and fabrication method for forming oxide isolation regions in a semiconductor substrate for use in forming self-aligned, floating gate MOS structures or other semiconductor devices. The method includes providing a semiconductor substrate member prefabricated having a barrier oxide layer, a polysilicon layer and a plurality of spaced apart silicon nitride layer portions fabricated on the polysilicon layer. The nitride layer portions delineate regions for forming the self-aligned floating gate MOS structures, as well as delineating portions of the silicon dioxide layer and portions of said polysilicon layer that are unprotected by the plurality of silicon nitride layer portions. The method further includes the step of implanting oxygen O2 ions into regions of the substrate, including those unprotected portions of the silicon dioxide layer and portions of the polysilicon layer to form the oxide isolation regions. After removing the silicon nitride layer portions, and exposing the polysilicon layer portions, the implanted structure is annealed and made ready for forming the self-aligned floating gate MOS structures, or other semiconductor structure on the conductive material pads. The floating gates may be formed having a minimal width with respect to an underlying active region.
