titleOfInvention |
Simultaneous location of areas having different conductivities |
abstract |
The process employs both silicon dioxide and silicon nitride layers used for selectively masking areas to be etched in order to allow a single photomask to be used for defining areas having different conductivities simultaneously, thereby eliminating problems caused by misregistry between photomasks. |
