    摘要: A method of manufacturing a semiconductor device includes forming a first metal pad in each of a plurality of first regions on a first substrate so that warpage is generated on the first substrate. The method further includes forming a second metal pad in each of a plurality of second regions on a second substrate via a predetermined pattern. The method further includes bonding, after forming the first metal pad and the second metal pad, the first substrate with the second substrate. Moreover, the method further includes: making a correction, at a time of forming the predetermined pattern in each of the plurality of second regions on the second substrate, to change a position of the predetermined pattern in each of the plurality of second regions in a direction of being closer to a center of the second substrate for a first direction and to change the position of the predetermined pattern in a direction of being farther from the center of the second substrate for a second direction.

    摘要: In the highly efficient fabrication processes for HNOR arrays provided herein, the channel regions of the storage transistors in the HNOR arrays are protected by a protective layer after deposition until the subsequent deposition of a charge-trapping material before forming local word lines. Both the silicon for the channel regions and the protective material may be deposited in amorphous form and are subsequently crystallized in an anneal step. The protective material may be silicon boron, silicon carbon or silicon germanium. The protective material induces greater grain boundaries in the crystallized silicon in the channel regions, thereby providing greater charge carrier mobility, greater conductivity and greater current densities.
