摘要： Transistor devices including stressors are disclosed. One such transistor device includes a channel region, a dielectric layer and a semiconductor substrate. The channel region is configured to provide a conductive channel between a source region and a drain region. In addition, the dielectric layer is below the channel region and is configured to electrically insulate the channel region. Further, the semiconductor substrate, which is below the channel region and below the dielectric layer, includes dislocation defects at a top surface of the semiconductor substrate, where the dislocation defects are collectively oriented to impose a compressive strain on the channel region such that charge carrier mobility is enhanced in the channel region.

摘要： An integrated circuit includes an SOI substrate with a unitary N+ layer below the BOX, a P region in the N+ layer, an eDRAM with an N+ plate, and logic/SRAM devices above the P region. The P region functions as a back gate of the logic/SRAM devices. An optional intrinsic (undoped) layer can be formed between the P back gate layer and the N+ layer to reduce the junction field and lower the junction leakage between the P back gate and the N+ layer. In another embodiment an N or N+ back gate can be formed in the P region. The N+ back gate functions as a second back gate of the logic/SRAM devices. The N+ plate of the SOI eDRAM, the P back gate, and the N+ back gate can be electrically biased at the same or different voltage potentials. Methods to fabricate the integrated circuits are also disclosed.

摘要： A method for fabricating an integrated circuit includes forming a temporary gate structure on a semiconductor substrate. The temporary gate structure includes a temporary gate material disposed between two spacer structures. The method further includes forming a first directional silicon nitride liner overlying the temporary gate structure and the semiconductor substrate, etching the first directional silicon nitride liner overlying the temporary gate structure and the temporary gate material to form a trench between the spacer structures, while leaving the directional silicon nitride liner overlying the semiconductor substrate in place, and forming a replacement metal gate structure in the trench. An integrated circuit includes a replacement metal gate structure overlying a semiconductor substrate, a silicide region overlying the semiconductor substrate and positioned adjacent the replacement gate structure; a directional silicon nitride liner overlying a portion of the replacement gate structure; and a contact plug in electrical communication with the silicide region.

摘要： Disclosed is an improved double patterning method for forming openings (e.g., vias or trenches) or mesas on a substrate. This method avoids the wafer topography effects seen in prior art double patterning techniques by ensuring that the substrate itself is only subjected to a single etch process. Specifically, in the method, a first mask layer is formed on the substrate and processed such that it has a doped region and multiple undoped regions within the doped region. Then, either the undoped regions or the doped region can be selectively removed in order to form a mask pattern above the substrate. Once the mask pattern is formed, an etch process can be performed to transfer the mask pattern into the substrate. Depending upon whether the undoped regions are removed or the doped region is removed, the mask pattern will form openings (e.g., vias or trenches) or mesas, respectively, on the substrate.
摘要翻译：公开了一种用于在基板上形成开口（例如，通孔或沟槽）或台面的改进的双重图案化方法。该方法通过确保衬底本身仅经历单次蚀刻工艺来避免现有技术的双重图案化技术中所见到的晶片形貌效应。具体地说，在该方法中，在衬底上形成第一掩模层并进行处理，使得其在掺杂区域内具有掺杂区域和多个未掺杂区域。然后，可以选择性地去除未掺杂区域或掺杂区域，以在衬底上方形成掩模图案。一旦形成掩模图案，就可以执行蚀刻工艺以将掩模图案转印到基板中。取决于未掺杂的区域是去除还是去除掺杂区域，掩模图案将分别在衬底上形成开口（例如，通孔或沟槽）或台面。

A wafer is provided having a substrate, a BOX and a SOI layer. A hardmask layer is deposited over the SOI layer. A photoresist layer is deposited over the hardmask layer and patterned into groups of segments. A tilted implant is performed to damage all but those portions of the hardmask layer covered or shadowed by the segments. Portions of the hardmask layer damaged by the implant are removed. A first etch is performed through the hardmask layer to form a deep trench in the SOI layer, the BOX and at least a portion of the substrate. The hardmask layer is patterned using the patterned photoresist layer. A second etch is performed through the hardmask layer to form shallow trenches in the SOI layer.
