A FinFET device includes a semiconductor fin, a gate electrode extending over a channel of the fin and sidewall spacers on each side of the gate electrode. A dielectric material is positioned on each side of a bottom portion of said fin, with an oxide material on each side of the fin overlying the dielectric material. A recessed region, formed in the fin on each side of the channel region, is delimited by the oxide material. A raised source region fills the recessed region and extends from the fin on a first side of the gate electrode to cover the oxide material to a height which is in contact with the sidewall spacer. A raised drain region fills the recessed region and extends from the fin on a second side of the gate electrode to cover the oxide material to a height which is in contact with the sidewall spacer.
