摘要： A technique for forming at least part of an array of a dual bit memory core is disclosed. A Safier material is utilized in the formation process to reduce the size of buried bitlines in the memory, which is suitable for use in storing data for computers and the like. The smaller (e.g., narrower) bitlines facilitate increased packing densities while maintaining an effective channel length between the bitlines. The separation between the bitlines allows dual bits that are stored above the channel within a charge trapping layer to remain sufficiently separated so as to not interfere with one another. In this manner, one bit can be operated on (e.g., for read, write or erase operations) without substantially or adversely affecting the other bit. Additionally, bit separation is preserved and leakage currents, cross talk, as well as other adverse effects that can result from narrow channels are mitigated, and the memory device is allowed to operate as desired.
摘要翻译：公开了一种用于形成双位存储器核心的阵列的至少一部分的技术。在形成过程中采用Safier材料以减小存储器中的埋置位线的尺寸，其适用于存储用于计算机等的数据。较小（例如较窄）的位线有助于增加打包密度，同时保持位线之间的有效通道长度。位线之间的间隔允许存储在电荷俘获层内的通道上方的双位保持充分分离，以便彼此不干扰。以这种方式，一个位可以被操作（例如，用于读取，写入或擦除操作）而基本上或不利地影响另一个位。此外，保留位分离，并且减轻了可能由窄通道产生的漏电流，串扰以及其他不利影响，并且允许存储器件根据需要进行操作。

摘要： 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.

摘要： The present invention pertains to implementing a lightly doped channel (LDC) implant in fashioning a memory device to improve Vt roll-off, among other things. The lightly doped channel helps to preserve channel integrity such that a threshold voltage (Vt) can be maintained at a relatively stable level and thereby mitigate Vt roll-off. The LDC also facilitates a reduction in buried bitline width and thus allows the bitlines to be brought closer together. As a result more devices can be formed or “packed” within the same or a smaller area.
摘要翻译：本发明涉及在形成存储器件中实施轻掺杂通道（LDC）植入物以改善Vt滚降等。轻掺杂通道有助于保持通道完整性，使得阈值电压（Vt）可以保持在相对稳定的水平，从而减轻Vt滚降。 LDC还有助于减少掩埋位线宽度，从而使位线更靠近在一起。因此，可以在相同或更小的区域内形成或“包装”更多的装置。
