Methods and structures that may be implemented in one example to co-integrate processes for thin-film encapsulation and formation of microelectronic devices and microelectromechanical systems (MEMS) such as sensors and actuators. For example, structures having varying characteristics may be fabricated using the same basic process flow by selecting among different process options or modules for use with the basic process flow in order to create the desired structure/s. Various process flow sequences as well as a variety of device design structures may be advantageously enabled by the various disclosed process flow sequences.
