Quality System

A Quality Control System that will Satisfy and Reassure the Customer

The ROHM organization is divided into a Research & Development Division, Production Division, Sales Division, Management Division, and departments directly administered by the president. Under the Production Division, manufacturing departments are organized corresponding to product groups (ICs, transistors, diodes, etc.), and management of quality, cost, and delivery schedules is conducted at this manufacturing department level.

*QC: Quality Control

Unbreakable Design and Product Creation

Semiconductors, which are produced through fine processes, are generally fragile. ROHM considers the importance to overturn this misconception in order to enable use with confidence. Taking the example of ICs, a Design Quality Development Department has been set up within the ICs Product Development Division as a specific organization. The activity of the Design Quality Development Department is diverse, for it includes not only to ensure design quality, but also to promote the development of circuitry and the introduction of protective circuits that do not break even when used under severe conditions.

Traceability Control

In the unlikely event where defects occur stemming from the product,the production information (lot information) of ROHM products can be traced back to the actual product. All manufacturing processes can be traced back to four factors:human,machine,material and method.These four factors enable a speedy investigation concerning the production conditions and workmanship of the pertinent lot.With respect to past products as well,a sample retention system is fully in place for all products,enabling re-verification of the state of products at a given time.
