摘要： The present invention provides a method to fabricate an organic memory device, wherein the fabrication method includes forming a lower electrode, depositing a passive material over the surface of the lower electrode, applying an organic semiconductor material over the passive material, and operatively coupling the an upper electrode to the lower electrode through the organic semiconductor material and the passive material. Patterning of the organic semiconductor material is achieved by depositing a silicon-based resist over the organic semiconductor, irradiating portions of the silicon-based resist and patterning the silicon-based resist to remove the irradiated portions of the silicon-based resist. Thereafter, the exposed organic semiconductor can be patterned, and the non-irradiated silicon-based resist can be stripped to expose the organic semiconductor material that can be employed as a memory cell for single and multi-cell memory devices. A partitioning component can be integrated with the memory device to facilitate stacking memory devices and programming, reading, writing and erasing memory elements.

摘要： The present invention provides systems and methods that facilitate formation of semiconductor devices via planarization processes. The present invention utilizes dishing effects that typically occur during a chemical mechanical planarization (CMP) process. A reducing CMP process is performed on a semiconductor device in order to form a passive layer instead of performing a first CMP, followed by a deposition and a second CMP to form a passive layer. The reducing CMP process utilizes a slurry that includes a reducing chemistry that forms the passive layer in a dish region of an electrode. Thus, the passive layer is formed in conjunction with the reducing CMP process utilized for forming the electrode.

摘要： The present invention provides a method for manufacturing a semiconductor device with a bottom anti-reflective coating (BARC) that acts as an etch stop layer and does not need to be removed. In one embodiment, electrical devices are formed on a semiconductor substrate. Contacts are then formed for each electrical device and a partially UV transparent BARC is then deposited. An inter-layer dielectric (ILD) layer is then formed and then covered with photoresist. A top ARC (TARC) is then added and the photoresist is then photolithographically processed and subsequently developed. The TARC, ILD, and BARC layers are then selectively etched down to the device contacts forming local interconnects. The photoresist and TARC are later removed, but the BARC does not require removal due to its optical transparency.

摘要： The dimensional accuracy of trench formation and, hence, metal line width, in damascene technology is improved by employing a low Si—SiON etch stop layer/ARC with reduced etch selectivity with respect to the overlying dielectric material but having a reduced extinction coefficient (k). Embodiments include via first-trench last dual damascene techniques employing a low Si—SiON middle etch stop layer/ARC having an extinction coefficient of about −0.3 to about −0.6, e.g., about −0.35, with reduced silicon and increased oxygen vis-à-vis a SiON etch stop layer having an extinction coefficient of about −1.1. Embodiments also include removing about 60% to about 90% of the low Si—SiON etch stop layer/ARC during trench formation, thereby reducing capacitance.
