Ultra-violet protected tamper resistant embedded EEPROM

A pre-metal dielectric structure of a single-poly EEPROM structure includes a UV light-absorbing film, which prevents the charge on a floating gate of the EEPROM structure from being changed in response to UV radiation. In one embodiment, the pre-metal dielectric structure includes a first pre-metal dielectric layer, an amorphous silicon layer located over the first pre-metal dielectric layer, and a second pre-metal dielectric layer located over the amorphous silicon layer.
