Abstract: A method is provided for creating optical features on a lithography mask for use in patterning a series of openings of an etch mask on a semiconductor device wafer, comprising creating a series of optical features spaced on the lithography mask from one another along a first direction, where the individual optical features have first mask feature dimensions along the first direction that are smaller than a desired first dimension for the openings to be patterned in the etch mask.

Abstract: A technique for forming at least part of an array of a dual bit memory core is disclosed. Initially, a portion of a charge trapping dielectric layer is formed over a substrate and a resist is formed over the portion of the charge trapping dielectric layer. The resist is patterned and a pocket implant is performed at an angle to establish pocket implants within the substrate. A bitline implant is then performed to establish buried bitlines within the substrate. The patterned resist is then removed and the remainder of the charge trapping dielectric layer is formed. A wordline material is formed over the remainder of the charge trapping dielectric layer and patterned to form wordlines that overlie the bitlines. The pocket implants serve to mitigate, among other things, complementary bit disturb (CBD) that can result from semiconductor scaling. As such, semiconductor devices can be made smaller and increased packing densities can be achieved by virtue of the inventive concepts set forth herein.

Abstract: A method of manufacturing an integrated circuit includes a semiconductor substrate having bitlines under a charge-trapping material over a core region and a gate insulator material over a periphery region. A wordline-gate material, a hard mask, and a first photoresist are deposited and patterned over the core region while covering the periphery region. After removing the first photoresist, wordlines are formed from the wordline-gate material in the core region. An anti-reflective coating and a second photoresist are deposited and patterned over the periphery region and covering the core region. The anti-reflective coating is removable without damaging the charge-trapping material. After removing the second photoresist and the anti-reflective coating, gates are formed from the wordline-gate material in the periphery region and the integrated circuit completed.

Abstract: A manufacturing method for a MirrorBit® Flash memory includes providing a semiconductor substrate and depositing a charge-trapping dielectric layer. First and second bitlines are implanted and a wordline layer is deposited. A hard mask layer is deposited over the wordline layer. The hard mask is of a material formulated for removal without damaging the charge-trapping dielectric layer. A photoresist is deposited over the wordline layer and used to form a hard mask. The photoresist is removed. The wordline layer is processed using the hard mask to form a wordline and the hard mask is removed. A salicide is grown without short-circuiting the first and second bitlines.
