“…The laser processed area (≈ 2.3 x 2.3 mm 2 ) is exposed to 500 to 10000 sequences (gas injection and laser pulse) with a constant laser energy density above the melting threshold (1290 mJ/cm 2 which corresponds to a melting duration of 80 ns). The laser induced melting process is in situ monitored by transient reflectivity (TR) at 675 nm and allows to determine the material melting threshold evolution during the process and the melting duration, which is correlated to the melted depth [12].…”

“…The duration of the plateau (20 to 85 ns) is related to the melting duration. Moreover, this duration tends to increase with the number of laser pulses, and so the melted depth, because of the modification of the optical and thermal properties of the doped material along the GILD process [12]. Then the TR signal decreases due to solidification process of the melted layer.…”

“…Thin films of boron doped silicon have been prepared by gas-immersion laser doping [3,4]. The surface of a silicon wafer is melted using laser pulses in the presence of a chemisorbed BCl 3 gas.…”

“…Cette technique permet d'introduire des ions á de très faibles énergies, ce qui correspond á des profondeurs d'implantation de quelques nanomètres. Cette étape est suivie d'un recuit d'activation effectué á l'aide d'un laser á excimère de type ArF [4][5][6][7]. Ce laser émettant dans l'UV, son énergie est absorbée dans les premiers nanomètres, et sa courte durée d'impulsion permet de limiter la diffusion des dopants.…”

“…Dans ce domaine de longueurs d'onde, la pénétration des photons dans le silicium est inférieure á 10 nm. La zone de charge d'espace devra se trouver en surface pour diminuer les pertes de signal par recombinaison.Pour commencer, nous présenterons les performances atteintes par l'association d'une implantation par immersion plasma (PIII : Plasma Immersion Ions Implantation) [1-3] et d'un recuit au laser á excimère (ELA : Excimer Laser Annealing) [4][5][6][7]. A l'aide de caractérisations électriques par mesures quatre pointes, nous pouvons estimer le niveau d'activation de nos jonctions.…”
