Patent ID: 7906405

Claim:
A method of forming an integrated circuit device, comprising: forming a dielectric layer over a substrate; forming a polysilicon layer over the dielectric layer; segmenting the polysilicon layer into strips of given width separated by segment gaps; forming sidewall spacers on lateral surfaces of the strips; implanting the polysilicon strips and adjacent areas of the substrate with dopants; performing a laser scan anneal by moving a laser beam of given wavelength at an acute angle incident to a top surface of the segmented polysilicon layer in a scan of the top surface with the laser beam moving directed parallel to the lateral surfaces of the strips; the given width being less than the given wavelength divided by twice an index of refraction of polysilicon at the given wavelength; forming a pre-metal dielectric layer over the annealed polysilicon strips; and forming contacts through the pre-metal dielectric layer for establishing contact with the underlying polysilicon strips.
