Patent ID: 8461005

Claim:
A method of manufacturing doping patterns comprising steps of: providing a substrate having a plurality of shallow trench isolations (STIs) formed therein, the STIs defining and electrically isolating a plurality of active regions having a same polarity of n-type or p-type, wherein forming the STIs comprises: providing a STI defining pattern to define a plurality of STI regions on the substrate; and forming the STIs respectively in the STI regions; forming a patterned photoresist having a plurality of exposing regions for exposing the active regions and the STIs in between the active regions on the substrate, wherein forming the patterned photoresist comprises: providing a predetermined doping pattern having a plurality of first dope-blocking regions and a plurality of first dope-exposing regions; comparing the predetermined doping pattern with the STI defining pattern; merging the first dope-exposing regions to form a modified doping pattern having a plurality of second dope-exposing regions and a plurality of second dope-blocking regions when the STI defining pattern is in between the adjacent first dope-exposing regions; and transferring the modified doping pattern to a photoresist to form the patterned photoresist; and performing an ion implantation to form a plurality of doping patterns in the active regions through the patterned photoresist, wherein at least two doping patterns have the same polarity of n-type or p-type are adjacent to and electrically isolated from each other by the STI.
