    摘要: An electrically, programmable read-only memory cell is formed at a face (10) of a semiconductor layer (12). This cell comprises a doped drain region (36) and a doped source region (38) that are spaced from each other by a gate region (40). An ONO memory stack (28) is formed to extend over a portion of the gate region (40) that adjoins the drain region (36). The memory stack (28) is substantially spaced from the source region (38). A select gate insulator layer (30) is formed over the remainder of the gate region (40), and is preferably of the same thickness as the memory stack (28). A suitable gate conductor (32) is then deposited over insulator layers (26, 30). By being substantially spaced from source region (38), the memory stack (28) of the invention avoids the formation of ONO hole traps.

    摘要: An X-cell EEPROM array includes a plurality of common source regions (50) that each border on four gate regions (46), both formed at a face of a semiconductor substrate (10). Each gate region (46) further adjoins a common drain region (52). Each drain region (52) is a common drain for two EEPROM select and memory transistors. A common erase region (54) is implanted into the semiconductor layer (10) in a position remote from the source regions (50) and the drain regions (52). Four floating gate electrodes (40) extend over tunnel windows (22) that are formed on the semiconductor layer (10) in positions adjacent a single erase region (54). An integral contact (64) is made through multilevel oxide (56, 58) from a metal erase line (70) to each erase region (54).

    摘要: An upstanding sidewall conductor (38) is formed in a via (30) that is made in a thick oxide layer (28) to expose a polysilicon gate electrode (22). A thin insulator layer (42) is deposited over the sidewall conductor layer (38) and a central region (32) of the polysilicon electrode (22). A second conductive layer (44) is deposited in the via (30) so as to be in registry with the upstanding sidewall conductor (38) and the central region (32) of the polysilicon electrode (22). In this way, the capacitive coupling between electrode (22) and electrode (44) is enhanced.

    摘要: The present invention provides a structure and method for fabricating that structure which provides increased capacitance over the prior art while occupying a minimum of surface area of the integrated circuit. The present invention accomplishes this by interleaving multiple capacitor plates to provide increased capacitance while occupying the same surface area as a prior art capacitor providing a fraction of the capacitance provided by the present invention. The present invention is fabricated by providing a capacitor stack which includes interleaved plates of material which may be selectively etched and which is separated by appropriate dielectric material. One portion of the stack is masked while one set of the interleave plates is etched. The etched portion of the interleave plates is filled by a suitable dielectric and a contact is made to the remaining plates. A different portion of the stack is then exposed to an etch which etches the other set of interleave plates. The area etched away is then filled with a suitable dielectric and a contact is made to the unetched interleaved plates. Thus a fully interleaved capacitor is provided using relatively simple fabrication techniques while still providing increased capacitance.
