    摘要: A 2-bit FinFET flash memory cell capable of storing 2 bits and a method of forming the same are provided. The memory cell includes a semiconductor fin on a top surface of a substrate, a gate insulation film on the top surface and sidewalls of a channel section of the semiconductor fin, a gate electrode on the gate insulation film, and two charge-trapping regions along opposite sides of the gate electrode, wherein each charge-trapping region is separated from the gate electrode and the semiconductor fin by a tunneling layer. The memory cell further includes a protective layer on the charge-trapping regions. Each of the two charge-trapping regions is capable of storing one bit. The memory cell can be operated by applying different bias voltages to the source, the drain, and the gate of the memory cell.

    摘要: A self-aligned conductive spacer process for fabricating sidewall control gates on both sides of a floating gate for high-speed RAM applications, which can well define dimensions and profiles of the sidewall control gates. A conductive layer is formed on the dielectric layer to cover a floating gate patterned on a semiconductor substrate. Oxide spacer are formed on the conductive layer adjacent to the sidewalls of the floating gate. Performing an anisotropic etch process on the conductive layer and using the oxide spacers as a hard mask, a conductive spacers are self-aligned fabricated at both sides of the floating gate, serving as sidewall control gates.

    摘要: An integrated circuit layout includes dense figures and at least one isolated figure. A plurality of dummy patterns are formed to surround the isolated figure, so as to reduce the difference in pattern density of the integrated circuit layout. A transmitted light of the dummy patterns provides a phase difference of 0 or 180 degrees relative to a transmitted light of the integrated circuit layout. The integrated circuit layout and the plurality of dummy patterns are formed on a photo-mask.

    摘要: A method of forming a dual damascene structure. A substrate having a conductive layer thereon is provided. A passivation layer, a first dielectric layer, an etching stop layer, a second dielectric layer and cap layer serving as a base anti-reflection coating are sequentially formed over the substrate. The cap layer and the second dielectric layer are patterned to form a first opening that exposes a portion of the etching stop layer. A patterned negative photoresist layer having a second opening therein is formed above the cap layer. The cap layer exposed by the second opening and the second dielectric layer exposed by the first opening are removed. Thereafter, the second dielectric layer exposed by the second opening is removed to form a trench and the first dielectric layer exposed by the first opening is removed to form a via opening. The passivation layer exposed by via opening and then the negative photoresist layer is removed. A conformal barrier layer and a conductive layer are sequentially formed over the trench and the via opening with the conductive layer, completely filling the trench and the via opening.

    摘要: A method of fabricating a dual damascene opening in a dielectric layer above a substrate. A first photoresist layer having a first opening therein is formed over the dielectric layer. The first opening exposes the dielectric layer at a position where a via is desired. A buffer layer is formed over the first photoresist layer. A second photoresist layer having a second opening is formed over the buffer layer. The second opening exposes the area where a conductive wire is desired. The first opening and the second opening together form a metallic interconnect structure. Using the first and the second photoresist layer as a mask, a dual damascene structural opening that includes a via opening and a conductive wire trench is formed in the dielectric layer.

    摘要: A three-phase phase shift mask. On a transparent substrate, a non-transparent pattern covering a portion of the transparent substrate is formed, while the other portion of the substrate is remained exposed. A proximity region around a comer of the non-transparent pattern is equally partitioned three phase-shift areas different from each other with a phase shift of 120°. The formation of these three phase-shift areas uses two etching steps to form a first and a second phase-shift areas, while a portion of the exposed substrate is etched twice as a third phase-shift area.
