2、n prepared, reviewed, and approved through the JEDEC Board of Directors level and subsequently reviewed and approved by the JEDEC legal counsel. JEDEC standards and publications are designed to serve the public interest through eliminating misunderstandings between manufacturers and purchasers, faci

3、litating interchangeability and improvement of products, and assisting the purchaser in selecting and obtaining with minimum delay the proper product for use by those other than JEDEC members, whether the standard is to be used either domestically or internationally. JEDEC standards and publications

4、 are adopted without regard to whether or not their adoption may involve patents or articles, materials, or processes. By such action JEDEC does not assume any liability to any patent owner, nor does it assume any obligation whatever to parties adopting the JEDEC standards or publications. The infor

5、mation included in JEDEC standards and publications represents a sound approach to product specification and application, principally from the solid state device manufacturer viewpoint. Within the JEDEC organization there are procedures whereby a JEDEC standard or publication may be further processe

6、d and ultimately become an ANSI standard. No claims to be in conformance with this standard may be made unless all requirements stated in the standard are met.

11、IE PRODUCTS INCLUDING KNOWN GOOD DIE (KGD) Foreword This standard was created to facilitate the procurement and use of semiconductor die products provided in bare or bumped die form. This document provides requirements and guidance to die suppliers in regard to the levels of as-delivered performance

12、, quality and reliability expected of this product type. It also reflects the special needs of die product customers in terms of design and application data. This document is applicable to die products used in both commercial and military applications. This standard also reflects an understanding on

13、 the part of the die product user that quality and reliability cannot always be assured in the same fashion as for conventionally packaged microcircuits. Die product customers take on a significant responsibility for the proper application and long-term environmental protection of this type of produ

14、ct. The extent to which a supplier shall assure die products is highly dependent upon the customers capability and adherence to strict quality controls. Cooperation between suppliers and users is essential. JEDEC Standard No. 49A.01 Page 1 PROCUREMENT STANDARD FOR SEMICONDUCTOR DIE PRODUCTS INCLUDIN

15、G KNOWN GOOD DIE (KGD) (From JEDEC Board Ballot JCB-05-100, formulated under the cognizance of the JC-13 Committee on Government Liaison.) 1 Scope This standard provides guidelines and requirements for die products used in other than conventionally packaged microcircuit or discrete formats. The die

16、described herein are intended to be high quality, reliable bare die, for use in a variety of user-defined applications (e.g., multi-chip modules (MCM), System in a Package (SiP), memory cards, etc.) While this standard allows negotiation between supplier and user to establish specific requirements f

17、or performance, quality and reliability, it is important to recognize, in the case of military and aerospace applications, the minimum requirements described in relevant military specifications. This standard is limited to die products consisting of a single microcircuit or discrete device connected

18、 using conventional wire bonding or High Density Interconnect. KGD products are intended to be equivalent to or better than comparable packaged parts in terms of electrical and reliability performance (unless specifically noted by the supplier). Per requirements mutually agreed upon by the KGD suppl

19、ier and user, the KGD supplier shall implement and demonstrate testing and screening required to assure this performance. This standard deals only with die products supplied in individual die form, for which the user accepts responsibility for providing and assuring final environmental protection (e

20、.g., hermetic sealing, plastic encapsulation). 2 Reference documents 2.1 Military and Federal Standards1 MIL-STD-883, Microelectronics, Test Methods, and Procedures MIL-PRF-19500, General Specification for Semiconductor Devices MIL-PRF-38534, General Specification for Hybrid Microcircuits MIL-PRF-38
