Control of Vmin transient voltage drift by using a PECVD silicon oxynitride film at the protective overcoat level
A method for fabricating a non-FLASH integrated circuit that minimizes Vmin shift. A protective overcoat ( 134 ) is deposited to protect and encapsulate the top metal interconnect layer ( 118 ). The protective overcoat ( 134 ) comprises silicon oxynitride. The protective overcoat ( 134 ) is patterne...

| Zusammenfassung: | A method for fabricating a non-FLASH integrated circuit that minimizes Vmin shift. A protective overcoat (
134
) is deposited to protect and encapsulate the top metal interconnect layer (
118
). The protective overcoat (
134
) comprises silicon oxynitride. The protective overcoat (
134
) is patterned and etched to form bondpad windows either before or after depositing the final metal interconnect layer (
136
). |
