QA is an essential part of the semiconductor manufacturing process. Because thin silicon wafers are becoming increasingly important in the industry, semiconductors continue to grow more and more sensitive to impurities or other imperfections.

The smallest contamination can cause major functionality issues. This is where Outsourced Semiconductor Assembly and Test (OSAT) companies are designed to help. Today, we’ll discuss everything you need to know about their role in the wafer industry.

What Do Outsourced Semiconductor Assembly and Test Companies Do?

As the name suggests OSAT companies are third-party businesses that perform quality control on semiconductors. They also often take on responsibility for packaging the semiconductor, which allows it to be used in electrical devices.

The packaging is also designed to protect the semiconductor. Once they’re outside of facilities specifically designed to minimize impurities, semiconductors still need to be able to do what they’re supposed to. Packaging allows them to withstand moisture and other materials.

Why OSATs are Important

The semiconductor manufacturing cycle is split among many different parties: first, semiconductor materials like silicon need to be mined out of the ground. Semiconductors then need to be designed, manufactured, packaged, and more.

When the time and capacity of a semiconductor fab needs to be maximized, OSATs take on time-consuming tasks, allowing for a great supply of semiconductors.
