MIL-PRF-19500 Semiconductor Devices, General Specification ForThis specification establishes the general performance requirements for semiconductor devices. Product assurance is provided by effective screening, conformance inspection, and process controls to mitigate risk. Mission assurance and standardization of parts are the highest priorities. This specification establishes a heritage program of semiconductor devices the military and space community can rely on to be dependable and available. Detail requirements and characteristics are specified in the specification sheets. Revisions to this specification and specification sheets are structured to assure the interchangeability of devices of the same part type regardless of manufacturing date code or conformance inspection \(CI\) completion date. Four quality levels for encapsulated devices are provided for in this specification, differentiated by the prefixes JAN, JANTX, JANTXV, and JANS. Eight radiation hardness assurance \(RHA\) levels are provided for the JANTXV and JANS quality levels. These are designated by the letters M, D, P, L, R, F, G, and H following the quality level portion of the prefix. Two quality levels for unencapsulated devices are provided for in this specification, differentiated by the prefixes JANHC and JANKC.

APPENDIX D

D.3.4 Critical interface control.

D.3.4.1 Design, materials, and processing documentation. Each product design shall be fully specified such that

all aspects of design, verification testing, processing, and materials are described. In addition, each manufacturer

shall have a flow chart, traveler, and DLA Land and Maritime Form 36D for each certified product line (see qualifying

activity).

D.3.4.2 Design changes. After qualification, the manufacturer shall notify the qualifying activity prior to the release

and shipment (for JANS prior to line implementation, except for evaluation samples) of product which undergoes any

change in the product or verification program which affects performance, quality, appearance, reliability, or

interchangeability (see appendix E-III, table E-III). The changes shall be approved by the qualifying activity prior to

release and shipment of product. Changes in design, materials, or processes for any device shall be processed in

accordance with established change control procedures for all affected documents (see D.3.6.1 and D.3.7). Such

notification shall include a thorough description of the proposed change and a test plan designed to demonstrate that

the change will not adversely affect performance, quality, reliability, or interchangeability and that the changed

product will continue to meet all specification requirements. The completed test results shall be approved by the

qualifying activity. After approval of the design change, all product inventory of the old design shall be submitted to

CI within 6 months, unless authorization is extended by the qualifying activity (see H.3.1). Unless the design change

has been required to correct or eliminate a verified design defect, finished devices manufactured to the previously

approved design which are in inventory or in process of testing (i.e., inspection lot identification code assigned) will

remain qualified only until that inventory is depleted.

D.3.5 Document control.

D.3.5.1 Document control procedures. The manufacturer shall establish and maintain procedures to control all

documents that relate to the requirements of this specification. This includes, to the extent applicable, military and

industry specifications and standards and their revisions, amendments, and notices. The manufacturer's procedures

are required to be in a language that is understandable by the operator performing the given operation.

D.3.5.2 Document approval and issue. Documents shall be reviewed and approved for adequacy by authorized

personnel prior to issue. A procedure shall be established to ensure that the current issue of appropriate documents

are available at all required locations, that invalid or obsolete documents are promptly removed from all points of

issue, and that any obsolete documents which are retained are suitably identified.

D.3.5.3 Document changes. Unless designated otherwise, changes to documents shall be reviewed and approved

by the same functions/organizations that performed the original review and approval.

D.3.6 Purchasing.

D.3.6.1 Acquisition documentation. A system for the acquisition of supplies and approval of suppliers shall be

established.

D.3.7 Control of customer supplied material. The manufacturer shall establish and maintain procedures for the

control, verification, maintenance and storage, as applicable, of customer supplied materials and equipment. Any

material which is lost or becomes unsuitable for use shall be recorded and reported to the customer.

D.3.8 Product identification and traceability. All devices delivered to this specification shall be traceable through

the lot identification code and inspection lot records, and identified as in D.3.9 through D.3.12, inclusive. In addition,

JANS devices shall have a lot control system from wafer processing through screening which provides wafer lot

identification; operation (machine), date of operation, operator(s) identification, quantity, and serial numbers (after

step 8 of appendix E, table E-IV) of devices processed.
