Products qualified and listed with DSCC

e2v qualifies a larger percentage of its QP Semi product lines in full compliance with MIL-PRF-38535 requirements and submits these qualifications for listing with DSCC than any other manufacturer. Current levels of support from all QML manufacturers are analyzed via data provided by DSCC and published via this linked page: Number of Qualified Devices Ranked by Vendor. This hyperlink to DSCC provides the full list of all devices QML qualified for e2v aerospace and defense inc. (QP Semiconductor): Devices Listed with DSCC for e2v aerospace and defense (QP Semiconductor).
 

DSCC approved test methods

Laboratory Suitability to MIL-STD-883 Test Methods was originally approved by DSCC in July 1997, and re-certified on July 17, 2003 and November 10, 2004. Laboratory Suitability Certification letter

Product quality and reliability

All new products are designed to meet MIL-PRF-38535 requirements, including metallization, step coverage and current density.

Scanning electron microscope (SEM) inspections are performed on procured wafers and die to verify the step coverage and current density requirements of MIL-PRF-38535.

All standard products are screened to the requirements of MIL-PRF-38535. This includes MIL-STD-883 Method 5004 screening and MIL-STD-883 method 5005 Qualification and Quality Conformance procedures.

Traceability to the wafer lot is maintained throughout manufacturing. A unique mark lot number is marked on the finished device for this purpose.
 

Die qualification testing

For die or wafers manufactured by an uncertified source, Qualification testing is performed per e2v aerospace and defense inc. (QP Semiconductor) QAP-27, Table 1 .

For Qualification of die or wafers from a DSCC certified source, the same testing is performed per e2v aerospace and defense inc. (QP Semiconductor) QAP-27, Table 1 with the exception of Subgroups D3 and D4 which are done as part of the periodic Group D QCI testing.
