Abstract: A semiconductor structure is presented including source/drain (S/D) epitaxial growth formed over a bottom dielectric isolation region, at least one first semiconductor layer disposed within the S/D epitaxial growth in a S/D region and at least one second semiconductor layer disposed partially within a gate region. The at least one second semiconductor layer extends from the gate region into a spacer region to enable a connection to the S/D epitaxial growth. The semiconductor structure further includes a first region with adjacent devices exhibiting a first Contacted gate Poly Pitch (CPP) defining a first gate-to-gate space and a second region with adjacent devices exhibiting a second CPP defining a second gate-to-gate space, where adjacent devices exhibiting the first CPP have a smaller gate-to-gate canyon than the adjacent devices exhibiting the second CPP such that the second gate-to-gate space is greater than the first gate-to-gate space.

Abstract: Semiconductor device designs having a buried power rail with a sloped epitaxy buried contact are provided. In one aspect, a semiconductor FET device includes: at least one gate disposed on a substrate; source and drains on opposite sides of the at least one gate, wherein at least one of the source and drains has a sloped surface; a buried power rail embedded in the substrate; and a buried contact that connects the buried power rail to the sloped surface of the at least one source and drain. Sidewall spacers separate the buried power rail from the substrate. A top of the sloped surface of the at least one source and drain is above a top surface of the buried contact. Methods of forming a semiconductor FET device are also provided.

Abstract: Large grain metal bitlines are formed above magnetic tunnel junction pillars used as MRAM bits without materially affecting the magnetic properties of the magnetic tunnel junctions. A copper or copper alloy bitline having relatively small grains is formed over the pillars. Laser annealing is employed to melt the bitline. Subsequent cooling and recrystallization results in a reduction of the number of grain boundaries in the bitline and a reduction in bitline effective resistivity. Multiple melt/cool cycles may be used. Bitline grains are vertically aligned with the pillars in a resulting structure.

Abstract: A hardened gap fill dielectric material that has improved chemical and physical properties is formed laterally adjacent to a multilayered magnetic tunnel junction (MTJ) pillar and a top electrode structure of a memory structure. The harden gap fill dielectric material can be formed by introducing, via ion implantation, a bond breaking additive into an as deposited gap fill dielectric material layer and thereafter curing the gap fill dielectric material layer containing the bond breaking additive. The curing includes UV curing alone, or UV curing in combination with laser annealing. The curing employed in the present application does not negatively impact the MTJ pillar or top electrode structure.

Abstract: A method for reducing series resistance for transistors includes forming a conductive gate over and insulated from a semiconductor substrate, forming source and/or drain extension regions within the substrate and adjacent to respective source and/or drain regions, and forming source and/or drain regions within the substrate. The source and/or drain extension regions are formed from a material alloyed with a first dopant and a second dopant, the first dopant configured to increase a lattice structure of the material forming the source and/or drain extension regions.

Abstract: An extreme ultraviolet (EUV) radiation source pellet(8) includes at least one metal particle (30) embedded within a heavy noble gas cluster (20) contained within a noble gas shell cluster (10). The EUV radiation source assembly can be activated by a sequential irradiation of at least one first laser pulse and at least one second laser pulse. Each first laser pulse generates plasma by detaching outer orbital electrons from the at least one metal particle (30) and releasing the electrons into the heavy noble gas cluster(20). Each second laser pulse amplifies the plasma embedded in the heavy noble gas cluster (20) triggering a laser-driven self-amplifying process. The amplified plasma induces inter-orbital electron transitions in heavy noble gas and other constitute atoms leading to emission of EUV radiation. The laser pulsing units can be combined with a source pellet generation unit to form an integrated EUV source system.
