    • A method for fabricating a memory cell array, in particular an EPROM or EEPROM memory cell array, includes burying insulation zones on a silicon substrate in accordance with an STI (Shallow Trench Isolation) technique, forming word lines on the insulation zones, covering the word lines with a hard mask and side wall oxides and CVD depositing an oxide or nitride laterally onto the hard mask and onto the side wall oxides to define a spacer. Spacer channels are etched into the insulation zones between adjoining word lines. An SAS (Self Aligned Source) resist mask is applied to mask each two adjacent coated word lines on mutually facing sections, including the spacer channel located between these word lines, while each two adjacent masked word lines of masked word line pairs remain unmasked on mutually facing sections. The SAS resist mask is exposed. Those regions of the insulation zones which are not covered by the SAS perforated mask are anisotropic etched, with a bottom of uncovered spacer channels being lowered down at least to a surface of the uncovered silicon substrate. The SAS perforated mask is removed to uncover a resultant structure.
    • 一种用于制造存储单元阵列,特别是EPROM或EEPROM存储单元阵列的方法,包括根据STI(浅沟槽隔离)技术在硅衬底上埋设绝缘区,在绝缘区上形成字线,覆盖字 具有硬掩模和侧壁氧化物的线和CVD将氧化物或氮化物横向沉积到硬掩模上并到侧壁氧化物上以限定间隔物。 间隔通道被蚀刻到相邻字线之间的绝缘区域中。 应用SAS(自对准源)抗蚀剂掩模来掩蔽相互面对的部分上的每两个相邻涂覆的字线,包括位于这些字线之间的间隔通道,而掩蔽的字线对的每两个相邻的被掩蔽的字线保持相互掩蔽 面向部分。 SAS抗蚀剂掩模露出。 未被SAS穿孔掩模覆盖的绝缘区域的那些区域是各向异性蚀刻的,未覆盖的间隔物通道的底部至少下降至未覆盖的硅衬底的表面。 移除SAS穿孔的面罩以露出所得到的结构。

    • The read only memory has a plurality of conductor track planes one above the other. The conductor tracks in adjacent planes are oriented such that they intersect in intersecting regions. In these intersecting regions, either a VIA tunnel contact is provided, which represents a logic "1" or no VIA tunnel contact is provided, so that this intersecting region represents a logic "0". In this way, over the same surface area, a plurality of memory cells can be produced one above the other. The read only memory is produced with a defined sequence of process steps and it is operated by selectively applying predetermined voltages across the various conductor tracks.
    • 只读存储器具有多个导体轨道平面,一个在另一个之上。 相邻平面中的导体轨迹定向成使得它们在交叉区域相交。 在这些相交区域中,提供VIA隧道触点,其表示逻辑“1”或不提供VIA隧道触点,使得该相交区域表示逻辑“0”。 以这种方式,在相同的表面积上,可以彼此重复地制造多个存储单元。 只读存储器以规定的处理步骤顺序产生,并且通过选择性地在各种导体轨道上施加预定电压来操作该只读存储器。
