N-well implant

http://www.essderc2002.deis.unibo.it/data/pdf/Chew.pdf WebThis implant is directed to electrically compensate the channeled N well dopants below the shallow trench isolation. The boron dose is kept low because a relatively low percentage of N well ions experience channeling, the bulk of them residing at the first, more shallow implant peak 314.
