What are OSAT in semiconductor?
6 answers
Outsourced Semiconductor Assembly and Test (OSAT) companies play a crucial role in the semiconductor manufacturing process by providing specialized services that include the assembly, packaging, and testing of semiconductor devices. These services are financially advantageous as they allow semiconductor companies to outsource key steps of the production process to firms with the necessary expertise and infrastructure, thereby reducing capital expenditure and focusing on core competencies such as design and innovation. OSAT companies are equipped to handle various aspects of semiconductor packaging and testing, including the development of fine pitch Through-Silicon Vias (TSVs) interposers, which are essential for creating high-density interconnections in multi-chip modules. This capability is significant as it provides a commercially viable technology path for semiconductor companies looking to leverage advanced packaging techniques without the need for extensive in-house facilities. However, outsourcing to OSAT companies is not without risks, particularly concerning the security of on-chip assets. The process of testing at OSAT facilities can potentially expose sensitive design and functionality details to untrusted parties. To mitigate these risks, techniques such as scan chain obfuscation are employed to hide the actual scan data from testers by inserting logic driven by a secret key between the scan cells. Despite these measures, recent studies have shown that attacks like ScanSAT can break these obfuscation techniques, highlighting the ongoing challenge of securing semiconductor designs in the OSAT environment. In summary, OSAT companies are integral to the semiconductor industry, offering essential assembly and testing services that enable the production of complex semiconductor devices. While they offer significant cost and efficiency benefits, the security of intellectual property remains a critical concern that requires ongoing attention and innovation.
