MIL-PRF-38535H, PERFORMANCE SPECIFICATION: INTEGRATED CIRCUITS (MICROCIRCUITS) MANUFACTURING, GENERAL SPECIFICATION FOR (16 MAR 2007)., This specification establishes the general performance requirements for integrated circuits or microcircuits and the quality and reliability assurance requirements, which are to be met for their acquisition. The intent of this specification is to allow the device manufacturer the flexibility to implement best commercial practices to the maximum extent possible while still providing product that meets military performance needs. Detail requirements, specific characteristics of microcircuits, and other provisions which are sensitive to the particular use intended will be specified in the device specification. Quality assurance requirements outlined herein are for all microcircuits built on a manufacturing line which is controlled through a manufacturer's quality management (QM) program and has been certified and qualified by the Qualifying Activity (QA) in accordance with requirements herein. Several levels of product assurance including RHA are provided for in this specification. The certification and qualification sections found herein outline the requirements to be met by a manufacturer to be listed on a Qualified Manufacturer Listing (QML).
