    Abstract: A method for fabricating a SONOS device having a buried bit-line including the steps of: providing a semiconductor substrate having an ONO structure overlying the semiconductor substrate; forming a nitride barrier layer on the ONO structure to form a four-layer stack; forming a patterned photoresist layer on the nitride barrier layer; implanting As or P ions through the four-layer stack to form a bit-line buried under the ONO structure; stripping the photoresist layer and cleaning an upper surface of the four-layer stack; and consolidating the four-layer stack by applying an oxidation cycle. The invention further relates to a SONOS-type device including the nitride barrier layer.

    Abstract: Dummy wordlines are provided between gaps of blocks of memory cells to compensate for higher charge loss at higher stress temperatures exhibited at edge wordlines of blocks of memory cells having large gaps. The dummy wordlines minimize the gap between the blocks. The dummy wordlines can be positioned between the blocks. Alternatively, the wordline width for the last block or sector wordline can be changed or different nitride used with less conductance in high temperatures. The dummy wordlines are typically ignored in normal operations on the memory.

    Abstract: A manufacturing method of a multi-level cell NOR flash memory includes the steps of forming a memory cell area and a peripheral circuit area with the same depth of a shallow trench isolation structure, and the depth ranges from 2400 Å to 2700 Å; forming a non-self-aligned gate structure; performing a self-alignment source manufacturing process; and forming a common source area and a plurality of drain areas. The manufacturing method achieves a high integration density between components and provides a better thermal budget and a better dosage control to the multi-level cell NOR flash memory to improve the production yield rate.

    Abstract: In a manufacturing method of a straight word line NOR flash memory array, a source line is implanted after the formation of a word line in the NOR type flash memory array is completed, and a discrete implant region is formed in the NOR type flash memory array and parallel to a component isolation structure, and each discrete implant region constitutes an electric connection with a low impedance between a source line and source contacts on the source line. With such discrete distribution, adjacent memory cells will not be short-circuited or failed even if a deviation of a mash occurs during the manufacturing process.
