But the self aligned approach might be difficult, or even impossible, in case of in-depth integrated PPDs for these very small pixels. These in-depth integrated PPDs need high implant energies. Thus the dopants will pierce through the relatively thin polygate (<200nm), which makes self alignment difficult or impossible.Anonymousnoreply@blogger.comtag:blogger.com,1999:blog-19092890.post-84769041258902507712019-04-10T22:34:38.207+03:002019-04-10T22:34:38.207+03:00So, they still use a no self-align approach...So, they still use a no self-align approach...Anonymousnoreply@blogger.com
