摘要： A memory cell in an integrated circuit is fabricated in part by forming a lower electrode feature, an island, a sacrificial feature, a gate feature, and a phase change feature. The island is formed on the lower electrode feature and has one or more sidewalls. It comprises a lower doped feature, a middle doped feature formed above the lower doped feature, and an upper doped feature formed above the middle doped feature. The sacrificial feature is formed above the island, while the gate feature is formed along each sidewall of the island. The gate feature overlies at least a portion of the middle doped feature of the island and is operative to control an electrical resistance therein. Finally, the phase feature is formed above the island at least in part by replacing at least a portion of the sacrificial feature with a phase change material. The phase change material is operative to switch between lower and higher electrical resistance states in response to an application of an electrical signal.

摘要： A method for simultaneously forming multiple line-widths, one of which is less than that achievable employing conventional lithographic techniques. The method includes providing a structure which includes a memory layer and a sidewall image transfer (SIT) layer on top of the memory layer. Then, the SIT layer is patterned resulting in a SIT region. Then, the SIT region is used as a blocking mask during directional etching of the memory layer resulting in a first memory region. Then, a side wall of the SIT region is retreated a retreating distance D in a reference direction resulting in a SIT portion. Said patterning comprises a lithographic process. The retreating distance D is less than a critical dimension CD associated with the lithographic process. The SIT region includes a first dimension W2 and a second dimension W3 in the reference direction, wherein CD

摘要： To isolate two active regions formed on a silicon-on-insulator (SOI) substrate, a shallow trench isolation region is filled with liquid phase deposited silicon dioxide (LPD-SiO2) while avoiding covering the active areas with the oxide. By selectively depositing the oxide in this manner, the polishing needed to planarize the wafer is significantly reduced as compared to a chemical-vapor deposited oxide layer that covers the entire wafer surface. Additionally, the LPD-SiO2 does not include the growth seams that CVD silicon dioxide does. Accordingly, the etch rate of the LPD-SiO2 is uniform across its entire expanse thereby preventing cavities and other etching irregularities present in prior art shallow trench isolation regions in which the etch rate of growth seams exceeds that of the other oxide areas.

摘要： An apparatus for immersion optical lithography having a lens capable of relative movement in synchrony with a horizontal motion of a semiconductor wafer in a liquid environment where the synchronous motion of the lens apparatus and semiconductor wafer advantageously reduces the turbulence and air bubbles associated with a liquid environment. The relative motions of the lens and semiconductor wafer are substantially the same as the scanning process occurs resulting in optimal image resolution with minimal air bubbles, turbulence, and disruption of the liquid environment.

摘要： A method for forming a gate for a FinFET uses a series of selectively deposited sidewalls along with other sacrificial layers to create a cavity in which a gate can be accurately and reliably formed. This technique avoids long directional etching steps to form critical dimensions of the gate that have contributed to the difficulty of forming FinFETs using conventional techniques. In particular, a sacrificial seed layer, from which sidewalls can be accurately grown, is first deposited over a silicon fin. Once the sacrificial seed layer is etched away, the sidewalls can be surrounded by another disposable layer. Etching away the sidewalls will result in cavities being formed that straddle the fin, and gate conductor material can then be deposited within these cavities. Thus, the height and thickness of the resulting FinFET gate can be accurately controlled by avoiding a long direction etch down the entire height of the fin.

摘要： A method for forming carbon nanotube field effect transistors, arrays of carbon nanotube field effect transistors, and device structures and arrays of device structures formed by the methods. The methods include forming a stacked structure including a gate electrode layer and catalyst pads each coupled electrically with a source/drain contact. The gate electrode layer is divided into multiple gate electrodes and at least one semiconducting carbon nanotube is synthesized by a chemical vapor deposition process on each of the catalyst pads. The completed device structure includes a gate electrode with a sidewall covered by a gate dielectric and at least one semiconducting carbon nanotube adjacent to the sidewall of the gate electrode. Source/drain contacts are electrically coupled with opposite ends of the semiconducting carbon nanotube to complete the device structure. Multiple device structures may be configured either as a memory circuit or as a logic circuit.
