APPENDIX D
D.3.2 Quality system program.
D.3.2.1 Quality system requirements. A quality system shall be established by each manufacturer which
implements all requirements of this appendix. This system shall be documented in a quality manual. The current
revision of the quality manual shall serve to demonstrate to the qualifying activity that the manufacturer's system is
adequate to assure compliance with the applicable specifications and quality standards. Proprietary documents shall
be clearly identified by category in the system.
D.3.2.2 Process flows. The system includes process flows for each distinct product family. As a minimum, flows
shall include wafer fabrication, assembly, screening, and conformance inspection (CI), and shall indicate which CI
option has been selected.
D.3.2.3 Quality system procedures. The manufacturer shall implement the approved system. The range and
detail of the procedures shall ensure compliance with this system
D.3.2.4 Quality planning. The manufacturer shall define how the requirements for quality will be met. Quality
planning shall be consistent with all other requirements of the manufacturer's quality system. The manufacturer shall
give consideration to the following activities, as appropriate, in meeting the specified requirements for products.
a.
The preparation of quality plans.
b.
The identification and acquisition of any controls, processes, equipment (including inspection and test
equipment), fixtures, resources, and skills that may be needed to achieve the required quality.
c.
Ensuring the compatibility of the design, production process, inspection, and test procedures.
d.
The updating, as necessary, of quality control, inspection, and testing techniques, including the
development of new instrumentation.
e.
The identification of any measurement requirement involving capability that exceeds the known state of the
art, in sufficient time for the needed capability to be developed.
f.
The identification of suitable verification at appropriate stages in the realization of product.
g.
The clarification of standards of acceptability for all features and requirements, including those which
contain a subjective element.
h.
The identification of all contracted processes. Unless approved by the qualifying activity, all devices
assembled in a contracted plant shall be tested (screening and CI) in the basic plant.
D.3.2.4.1 FMEA. Changes in design, materials, or processes for any device shall be reviewed in accordance with
established design control procedures. Tools can include process flow charts, control plans, SPC, DOEs, or FMEAs.
D.3.2.4.2 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.
D.3.2.4.3 Plant moves. For all plant moves, all die banking inventory information shall be made available to the
qualifying activity. All die not suitable for JAN assembly shall be controlled and identified. Die shall not be
transferred from one facility to another facility without the approval of the qualifying activity.
