Abstract: Single-chip solutions and related methods that result in much higher capacitance densities than is achievable with current on-chip solutions and which reduce consumption of planar area of a mounting structure. Embodiments of the present invention use vertical stacking to affix one or more discrete embeddable capacitors to an IC chip superstructure or base structure, and either sequentially or concurrently form electrical connections between the discrete embeddable capacitors and the IC chip. The inventive processes are compatible with CMOS fabrication temperatures for the IC chip while allowing use of capacitors that are fabricated using other processes that may involve much higher temperatures. The inventive processes allow connection of relatively large capacitances (e.g., ˜0.5 ?F-1 ?F) to an IC chip without increasing the 2-D footprint of the IC chip.

Abstract: A method includes forming a trench in a stack comprising a substrate, a buried oxide layer formed above the substrate, a semiconductor layer formed above the buried oxide layer and a hard mask layer formed above the semiconductor layer. A first liner is formed in the trench. A first oxide layer is formed in the trench. A diffusionless anneal process is performed to densify the first oxide layer. The first oxide layer is recessed to define a recess. A second oxide layer is formed in the recess.

Abstract: Methods are providing for fabricating transistors having at least one source region or drain region with a stressed portion. The methods include: forming, within a cavity of a substrate structure, the at least one source region or drain region with the internal stress; and resurfacing the at least one source region or drain region to reduce surface defects of the at least one source region or drain region without relaxing the stressed portion thereof.

Abstract: In-situ melting and crystallization of sealed cooper wires can be performed by means of laser annealing for a duration of nanoseconds. The intensity of the laser irradiation is selected such that molten copper wets interconnect interfaces, thereby forming an interfacial bonding arrangement that increases specular scattering of electrons. Nanosecond-scale temperature quenching preserves the formed interfacial bonding. At the same time, the fast crystallization process of sealed copper interconnects results in large copper grains, typically larger than 80 nm in lateral dimensions, on average. A typical duration of the annealing process is from about 10's to about 100's of nanoseconds. There is no degradation to interlayer low-k dielectric material despite the high anneal temperature due to ultra short duration that prevents collective motion of atoms within the dielectric material.

Abstract: Circuit structure fabrication methods are provided which include: providing an interlayer structure above a substrate, the interlayer structure including porogens dispersed within a dielectric material; and pulse laser annealing the interlayer structure to form a treated interlayer structure, the pulse laser annealing polymerizing the dielectric material of the interlayer structure to form a polymeric dielectric material, that includes pores disposed therein. The pulse laser annealing facilitates increasing elasticity modulus of the treated interlayer structure by, in part, maintaining structural integrity of the treated interlayer structure, notwithstanding that there are pores disposed within the polymeric dielectric material which, for instance, facilitates reducing dielectric constant of the treated interlayer structure.
