Abstract:
1. A method for processing integrated circuit devices, the method comprising: providing a monitor wafer, the monitor wafer comprising a silicon material; introducing a plurality of particles within a depth of the silicon material, whereupon the plurality of particles cause the silicon material to be in an amorphous state; introducing a plurality of dopant particles into a selected depth of the silicon material using an implantation tool, the amorphous state trapping the dopant particles; subjecting the monitor wafer including the plurality of particles and dopant particles into thermal anneal process to activate the dopant; removing the monitor wafer; measuring a sheet resistivity of a surface region including the implanted dopant particles of the monitor wafer; determining a dose of the dopant bearing impurities; and operating the implantation tool using one or more production wafers if the dose of the dopant particles in the monitor wafer is within a tolerance of a specification limit.
