Abstract
An integrated circuit package includes an electronic sensor protected by a lid structure. The electronic sensor includes a transducer placed on a backside surface of a lead frame assembly. The lid structure is placed over the transducer and is attached to the lead frame assembly on the backside surface. The lid can define an air cavity around the transducer, such that mold compound, gel, or other protective chemical material is not placed in contact with the transducer. The transducer is therefore protected without a chemical protectant, lowering the cost of the integrated circuit package and maintaining the sensitivity and performance of the transducer.
