6、f this web page is to focus on the activities and criteria that ADI uses to produce veryreliable and high-quality products that meet customers requirements.The site is also designed to conveythe embedded philosophies on quality and reliability that are embodied in every step of the manu-facturing pr

7、ocess and in all personnel.Also discussed is ADIs commitment to the customers needs andits quest for excellence through continuous improvement at all levels in the design,manufacturing,andsupport areas of the company.ADI Reliability CharterADI has always placed the highest emphasis on delivering pro

8、ducts that meet the customers totalrequirements and,as a result,generate complete customer satisfactioncritical for success and survivalin todays integrated circuit industry.This is achieved by incorporating quality and reliability checks notonly in all realms of product and process design,but in th

9、e manufacturing process as well.This isachieved through careful planning in the design phases of any new development or equipment introduc-tion into any of our facilities utilizing communication and teamwork.ADI strongly believes in thenecessity for cross-functional teams and the contributions of in

10、dividuals to attain excellence in qualityand reliability.Our employees are committed to the quality and reliability goals of the company and tocontinually improving the quality and reliability of Analogs processes and services on a global basis.Consequently,ADIs policy statement on quality is placed

11、 in all meeting rooms and in all prominentpositions throughout the plant to remind employees that the quest for total customer satisfaction is con-tinual and every employee has a responsibility in ensuring the quality objectives of Analog Devices.Quality Policy Statement“Analog Devices is committed

12、to establishment and continuous improvement of world class systems andprocesses aimed at satisfying our customers evolving needs.We embrace a total quality philosophy withan emphasis on prevention rather than detection.We focus on technology,quality,reliability,serviceand costs in order to make inno

13、vative solutions available to our customers at minimized total cost.”ADI Reliability Handbook2From this statement comes the ADI reliability goal:“The charter of the reliability groups in ADI is to consistently strive to ensure that the reliability of pro-duction,new products and processes developed

14、meet and exceed the industry reliability requirements.This is achieved by working in teams with development groups such as wafer fabrication,new productdesign,packaging and focusing on all aspects of product/process design,incorporating the combinedknowledge of the team with the classical bathtub cu

38、EPROCESS PHASESMILESTONESFigure 1.New Product Development ProcessThere are basically seven milestones in the release of any new product within ADI starting with thedesign initiation and ending with the release of the product.The process by which each of thesemilestones is met is divided into five di

39、stinct phases:1.Feasibility2.Implementation3.Wafer Fabrication4.Packaging and Validation5.ReleaseIf any step in the process is deemed not to be applicable to the development of a new product,thedevelopment team is responsible for documenting the reasons.These phases are outlined in Figure 1.Step one

40、 is the development of a PSD0.This document is a review of 12 critical factors highlighting thestrengths and weaknesses of the project.The development team uses it to create a high-quality PSD1.FeasibilityThe feasibility study begins with a product definition that can come from any number of sources

41、,suchas marketing,engineering,or directly from customers.Once agreement has been reached on productdefinition and feasibility,the product lines then allocate the generic model number in accordance withcorporate policy.An upper management team sponsor is appointed and a design team is formed consisti

42、ngof but not limited to:Design,CAD,Manufacturing,Test,Quality,and Reliability.During the feasibilityphase,design engineers assess how to meet market requirements,and various architectures and packageoptions are explored.The manufacturing process is selected,die size estimates are made,and timeframes

43、 are established for development and release.This work allows the product start document(PSD1)to be completed.ADI Reliability Handbook5During this stage various resources are allocated to the project and decisions made.An in-deptharchitecture review is conducted among the project designers and other

44、 design engineers outside theproject group to secure a balanced perspective on the proposed architecture.The product team alsoconvenes during this period to decide on the characterization plan for the product and to allocateresponsibilities.The designer will supply a high-level product simulation to

45、 enable the test engineer togain a good understanding of how the part will perform and to investigate Design for Test(DFT)strategies.Prior to completing the product start document,the design engineer will discuss with the relevantassembly engineer any issues related to assembly.CAD requirements are

46、also reviewed and resourcesallocated at this time.Once this step is completed,the PSD1 is signed off.The PSD1 is a controlleddocument and signifies the formal start of the project.The PSD outlines the roles and responsibilities ofthe team sponsor,leader,and members.In completing the PSD,the new prod

47、uct release team must gen-erate a schedule for development and release of the product outlining the resources required.Thetest feasibility phase begins once the assigned test engineer receives a controlled copy of the data sheet.During this phase the test engineer considers the technical risks invol

48、ved and where possible effort canbe made to eliminate these risks.The test engineer provides DFT inputs to the design engineer to givethe maximum coverage at the probe and final test stages.ImplementationPrior to commencing a detailed design,the development team generates a list of simulations plann

49、edduring the design phase.These simulations become the basis of the design review and at this point adetailed design is completed and a set of schematics produced.The design engineer calls a design reviewmeeting in which the engineer shows that the desired product performance can be achieved by prov

50、id-ing simulation data.If no changes are required,the design proceeds while the characterization plansare reviewed and updated as needed.The layout now begins in accordance with the specified designrules,and additional simulations are done to achieve full-chip simulation.Also during this phase,burn-
