Abstract: A method is provided for eliminating uneven heating of substrate active areas during laser thermal annealing (LTA) due to variations in gate electrode density. Embodiments include adding dummy structures, formed simultaneously with the gate electrodes, to “fill in” the spaces between isolated gate electrodes, such that the spacing between the gate electrodes and the dummy structures is the same as the spacing between the densest array of device structures on the substrate surface. Since the surface features (i.e., the gate electrodes and the dummy structures) appear substantially uniform to the LTA laser, the laser radiation is uniformly absorbed by the substrate, and the substrate surface is evenly heated.

Abstract: A method of manufacturing a MOSFET semiconductor device includes forming a gate electrode over a substrate and a gate oxide between the gate electrode and the substrate, forming source/drain extensions in the substrate, and forming first and second sidewall spacers. Dopants are then implanted within the substrate to form amorphitized source/drain regions in the substrate adjacent to the sidewalls spacers. The amorphitized source/drain regions are partially recrystallized, and laser thermal annealing activates the source/drain regions. The source/drain extensions and sidewall spacers are adjacent to the gate electrode. The source/drain extensions can have a depth of about 50 to 300 angstroms, and the source/drain regions can have a depth of about 400 to 1000 angstroms. Also, the recrystallization reduces the amorphitized source/drain regions by a depth of about 20 to 100 angstroms. A semiconductor device is also disclosed.

Abstract: A method of manufacturing a semiconductor device includes forming a gate electrode over a substrate, introducing dopants into the substrate, forming a tuning layer over at least a portion of the substrate, and activating the dopants using laser thermal annealing. The tuning layer causes an increase or a decrease in the amount of fluence absorbed by the portion of substrate below the tuning layer in comparison to an amount of fluence absorbed by a portion of substrate not covered by the tuning layer. Additional tuning layers can also be formed over the substrate.
