    摘要: A method of forming a conductive plug in an interlevel dielectric includes forming a lower dielectric layer over a semiconductor substrate. A first etch mask is formed over the lower dielectric layer and is patterned using a reticle. A first etch is applied through an opening in the first etch mask to form an opening in the lower dielectric layer. A lower conductor is formed in the opening in the lower dielectric layer. A conducting layer is formed over the lower dielectric layer and the lower conductor. A second etch mask is formed over the conducting layer and is patterned using the reticle. A second etch is applied through an opening in the second etch mask to form a contact pad from an unetched portion of the conducting layer. An upper dielectric layer is formed over the lower dielectric layer and the contact pad. A third etch mask is formed over the upper dielectric layer and is patterned using the reticle. A third etch is applied through an opening in the third etch mask to form an opening in the upper dielectric layer. An upper conductor is formed in the opening in the upper dielectric layer. As a result, the conductive plug includes the upper and lower conductors and the contact pad, and the interlevel dielectric includes the upper and lower dielectric layers.

    摘要: A process for breaking silicide stringers extending between silicide regions of different active regions on a semiconductor device is provided. Consistent with an exemplary fabrication process, two adjacent silicon active regions are formed on a substrate and a metal layer is formed over the two adjacent silicon active regions. The metal layer is then reacted with the silicon active regions to form a metal silicide on each silicon active region. This silicide reaction also forms silicide stringers extending from each silicon active region. Finally, at least part of each silicide stringer is removed. During the formation of the silicide stringers at least one silicide stringer may be formed which bridges the metal silicide over one of the silicon regions and the metal silicide over the other silicon region. In such circumstances, the removal process may, for example, break the silicide stringer and electrically decouple the two silicon regions. The two silicon active regions may, for example, be a gate electrode and an adjacet source/drain region. As another example, the two adjacent active regions may be two nearby polysilicon lines.

    摘要: An integrated circuit that has logic and a static random access memory (SRAM) array has improved performance by treating the interlayer dielectric (ILD) differently for the SRAM array than for the logic. The N channel logic and SRAM transistors have ILDs with non-compressive stress, the P channel logic transistor ILD has compressive stress, and the P channel SRAM transistor at least has less compressive stress than the P channel logic transistor, i.e., the P channel SRAM transistors may be compressive but less so than the P channel logic transistors, may be relaxed, or may be tensile. It is beneficial for the integrated circuit for the P channel SRAM transistors to have a lower mobility than the P channel logic transistors. The P channel SRAM transistors having lower mobility results in better write performance; either better write time or write margin at lower power supply voltage.

Multiple channel regions are provided on a substrate with a gate electrode formed on the uppermost channel region, separated by a gate oxide, for example. The vertical stacking of multiple channels and the gate electrode permit increased drive current in a semiconductor device without increasing the silicon area occupied by the device.

    摘要: A semiconductor device comprising a substrate having a first crystal orientation is provided. A first insulating layer overlies the substrate and a plurality of silicon layers overlie the first insulating layer. A first silicon layer comprises silicon having a second crystal orientation and a crystal plane. A second silicon layer comprises silicon having the second crystal orientation and a crystal plane that is substantially orthogonal to the crystal plane of the first silicon layer. Because holes have higher mobility in the (110) plane than the (100) plane, while electrons have higher mobility in (100) plane than the (110) plane, semiconductor device performance can be enhanced by the selection of silicon layers with certain crystal plane orientations. In addition, a method of forming a semiconductor device is provided. A silicon-on-insulator structure comprising a first silicon substrate having a first crystal orientation with a first insulating layer formed thereon and a first silicon layer having a second crystal orientation and a crystal plane overlying the first insulating layer is bonded to a second silicon substrate. The second silicon substrate has the second crystal orientation and a crystal plane and a second insulating layer formed thereon. The second silicon substrate comprises a line of defects created by implanting hydrogen ion into the second silicon substrate. The crystal plane of the second silicon substrate is oriented substantially orthogonal to the crystal plane of the first silicon layer. The second silicon substrate is split and removed along the line of defects leaving behind the second insulating layer and a second silicon layer on the silicon-on-insulator structure. A plurality of devices with different crystal orientations can be subsequently formed on a single, planar silicon-on-insulator structure by selectively etching the silicon-on-insulator structure down to silicon layers of different crystal orientations, growing selective epitaxial silicon layers in the etched regions, and subsequently planarizing the silicon-on-insulator structure by chemical-mechanical polishing.

    摘要: One method of forming a semiconductor device includes forming a gate electrode on a substrate and then forming a spacer adjacent to a sidewall of the gate electrode. An active region is formed in the substrate adjacent to the spacer and spaced apart from the gate electrode using a first dopant material of a first conductivity type. A protecting layer is formed over the active region and adjacent to the spacer. At least a portion of the spacer is then removed to form an opening between the protecting layer and the gate electrode. In some instances, the spacer may be formed by independent deposition of two different materials (e.g., silicon nitride and silicon dioxide), one of which can be selectively removed with respect to the other. A lightly-doped region is formed in the substrate adjacent to the gate electrode using a second dopant material of the first conductivity type. This lightly-doped region may be formed, for example, prior to formation of the spacer, between the formation of two portions of the spacer, or after removing at least a portion of the spacer. A halo region is formed through the opening resulting from removing a portion of the spacer. The halo region is deeper in the substrate than the lightly-doped region and is adjacent to the active region. The halo region is formed using a third dopant material of a conductivity type different than the first conductivity type.
