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 C

C.5 QUALITY PLANNING

C.5.1 Product quality planning. Quality planning is a controlled method of assuring that a product meets the

customer's performance needs. This is accomplished through characterization of all applicable technology families

and associated processes. Formal technology process flowcharts, FMEA's, and control plans shall be generated and

maintained under the manufacturer's document control system. All contracted processes shall be identified and

FMEA'S shall be performed for assembly and test.

C.5.1.1 Technology process flowchart. Flowcharts shall be generated for each certified technology. The flow chart

consists of a diagram showing the sequence of material processing from incoming material through final shipment,

including any production testing.

C.5.2 FMEA. The TRB is responsible for assuring that all actions recommended have been implemented or

adequately addressed in the FMEA's.

C.5.3 Control plans. The control plan is prepared to summarize the process control planning for each technology.

Product characteristics that should be included in a control plan are control item characteristics and significant

characteristics. The evaluation method, sampling plans, data analysis method, and out of control plans are part of

the control plan. Control plan updating should be tied to the corresponding FMEA updates.

C.6. QM CERTIFICATION

C.6.1 QM program certification process. The effectiveness of the manufacturer's QM program can only be

determined over time. Manufacturers shall have a working TRB in place prior to a QM program certification audit. A

comprehensive self-audit shall be performed by the manufacturer after a sufficient implementation period to get a

realistic snapshot of the QM program and TRB effectiveness. All correspondence sent to the qualifying activity shall

be first reviewed by the TRB. Results of such reviews are required for qualification reports and design changes.

These reviews will be used in part to gauge the effectiveness of the TRB. The following items are examples of pre-

audit submission:

Quality planning information.

Manufacturers QM plan (see C.3.1.1).

Quality policy.

TRB procedure (see C.4.1) and meeting minutes.

List of methods for lab suitability.

Self-audit results.

Appropriate documents to demonstrate compliance to MIL-PRF-19500 requirements.

The qualifying activity will review the pre-audit submissions for compliance to MIL-PRF-19500. Any initial concerns

will be addressed at this time. Additional information, such as detailed procedures may be requested. The audit will

be scheduled once all the pre-audit information is approved. The validation will focus on the TRB, QM plan, and

process controls for each technology family. Once corrective actions have been taken and approved by the

qualifying activity, certification will be issued.
