On July 1st, Toshiba Corporation's Semiconductor Company and Storage Products Company consolidated to form Semiconductor & Storage Products Company.This page describes reliability information of semiconductor products.

Control of Parts, Materials and Subcontracting

[As of April, 2011]

Parts and Materials

The assurance of high-quality parts and materials for the manufacturing process is essential to continued stable production at the designed levels of quality and reliability.
Therefore, the specifications and required quality standards for parts and materials are clearly defined in the manufacturing design phase. This information is used in the incoming parts and materials inspection and approval process (in the case of chemicals, periodic analysis).
Furthermore for parts and materials procured from outside vendors, a quality assurance agreement is concluded with the outside vendors to provide guidelines for:

Systemization of quality assurance implementation plan submission
Quality control (such as SPC) guidance and education
ISO 9000 Series based control and guidance
Process auditing

As environmental activity, Toshiba has promoted green procurement. For details on green procurement, refer to Green Prcuremoent.
In addition, parts and materials are stored in an appropriate environment in accordance with established rules to prevent deterioration over time and assure quality.

Subcontracting

When selecting a subcontractor/affiliate to do part of the semiconductor product manufacturing process, items such as QC, management, technology and facilities are investigated and confirmed.
After production starts, support is provided to aid affiliates and subcontractors in quality and engineering training and guidance and in facility planning. In addition, periodic quality audits are performed to check the process control and environment status.
Furthermore, affiliate and subcontractor quality meetings are held periodically to obtain action plans for items reported during quality audits, to verify the status of other quality items and to provide guidance in quality improvement, thereby maintaining and improving quality. Table 1 shows an example of an affiliate/subcontractor control plan and its implementation.
