Abstract
A semiconductor device includes a plasma-enhanced chemical vapor deposition (PECVD) protective layer configured to prevent failure of the semiconductor device throughout a temperature humidity with bias (THB) test exceeding about 1000 hours and/or a highly accelerated stress test (HAST) exceeding about 96 hours. Including a PECVD protective layer capable of protecting the semiconductor device throughout a THB test exceeding about 1000 hours and/or a HAST exceeding about 96 hours results in an extremely robust device, while providing the protective layer via PECVD results in convenience and cost savings.
