与任何行业一样,全球半导体领域自成立以来不断发展。
在北美,在过去十年中,遵循无晶圆厂商业模式的芯片供应商的比例大幅增加,其中绝大多数IDM和基于代工的制造业现在都在亚洲地区进行,而这些地区的劳动力成本要低得多。
微电子制造活动向海外地区的持续迁移对国防部门的供应链构成了重大风险。
有许多因素会影响军事和航空航天应用所需的关键任务电子系统。
这些包括伪造,逆向工程,篡改,特洛伊木马破坏,或仅仅是糟糕的制造实践(这可能导致系统可靠性受损)。
此外,在这种应用中使用的设计通常需要长期供应链支持 - 不像消费者或电信领域的那些。
确保长期供应库存至关重要。
需要高性能IC的基于防御的设计包括安全通信/数据加密系统,无人驾驶飞机,导弹制导仪器,雷达系统,GPS机制和热成像设备。应用的性能,集成和可靠性要求需要尖端,强大的技术
。
然而,半导体标准通常支持应用所需的单位体积非常低。
仅这些问题就可以使定制IC的采购成为一项挑战。
当考虑到制造源的安全性和连续性时,问题会进一步加剧。
为了确保IC资源的完整性,防止可能的供应中断并充分保护正在使用的知识产权,可信铸造计划于2004年成立。国防部(DoD)和国防部之间的这一联合项目的目标是
美国国家安全局(NSA)将认可可靠,安全的微电子元件开发和制造来源。
从那以后,该计划一直致力于为美国军方提供前沿可信微电子服务的保障,以及广泛的标准IP模块库。
最初该计划专注于一家非常大的半导体供应商。
然而很快就会发现某些IC需求无法满足。
随着时间的推移,该计划的范围已扩大到包括半导体供应链的其他组成部分。
迄今为止,国防部已为该计划投入了近7亿美元。
安森美半导体是位于爱达荷州波卡特洛和俄勒冈州格雷沙姆的制造工厂的1A类信托铸造厂。
这些晶圆厂可以在各种半导体技术上生产专用芯片。
经认证的Pocatello工厂拥有40,000平方英尺的占地面积洁净室,并支持从500纳米到350纳米数字和混合信号CMOS和BCD技术的各种工艺。
Gresham工厂拥有100,000平方英尺的洁净室空间,支持250纳米,180纳米和110纳米CMOS和BCD技术。
安森美半导体提供的各种可靠技术与其他供应商截然不同。
安森美半导体还获得了1A类可信经纪人和可信设计认证,使该公司能够通过其1A类可信赖合作伙伴监督可信赖的设计,测试,装配和资格流程,提供全面的可信ASIC解决方案。
由于存在如此多的利害关系,国防和航空航天部门必须能够获得最新的创新半导体技术,而不会受到干扰或阻碍(无论是恶意还是其他)的来源。
通过可信代工铸造计划,有可能消除微电子制造转向不安全的海上地点的潜在危险,并为美国军事关键任务应用获得可靠的供应链。
它创造了一个安全的环境,可以通过最先进的技术开发和制造国防部电子设计项目的半导体器件,同时消除供应链中伪造或篡改组件的存在
并持续长达数年的采购周期。

As with any industry, the global semiconductor landscape has continued to evolve since its inception. In North America the proportion of chip suppliers that follow a fabless business model has increased immensely over the last decade, with the vast majority of both IDM and foundry-based manufacturing now taking place in sites across Asia, where labor costs are far lower. This on-going migration of microelectronics fabrication activity to offshore locations poses a significant risk to the supply chain for the defense sector.
There are a number of factors that can impact mission critical electronic systems required for military and aerospace applications. These include counterfeiting, reverse engineering, tampering, trojan horse sabotage, or simply poor manufacturing practices (which could lead to compromised system reliability). In addition, designs utilized in applications of this kind will often require long-term supply chain support -unlike those in the consumer or telecom space. Securing prolonged availability of stock is of prime importance.
Defense based designs requiring high performance ICs include secure communications/data encryption systems, unmanned aircraft, missile guidance instrumentation, radar systems, GPS mechanisms, and thermal imaging equipment.The performance, integration, and reliability requirements of the applications demand cutting edge, robust technology. However the unit volumes required to support the applications are generally very low by semiconductor standards. These issues alone can make the sourcing of custom ICs a challenge. When the security and continuity of the manufacturing source are then taken into account, issues are compounded still further.
In order to ensure the integrity of IC sources, safeguard against possible disruption of supply and fully protect the IP that was being employed, the Trusted Foundry Program was established in 2004. The aim of this joint project between the Department of Defense (DoD) and the National Security Agency (NSA) was to accredit trusted, secure sources for the development and manufacture of microelectronic components. Since then the program has acted to provide the US military with guaranteed access to leading edge trusted microelectronics services, as well as an extensive library of standard IP blocks. Originally the program was focused on one very large semiconductor supplier. It was soon evident however that certain IC needs could not be met. Over time the scope of the program has been broadened to include additional components of the semiconductor supply chain. To date DoD has invested close to $700M into this program.
ON Semiconductor is a Category 1A Trusted Foundry for both its manufacturing facilities in Pocatello, Idaho and Gresham, Oregon. These fabs enable the production of application specific chips on a wide range of semiconductor technologies. The accredited Pocatello facility has a 40,000 ft2 floor space clean room and supports a variety of processes, from 500 nm down to 350 nm digital and mixed-signal CMOS and BCD technologies. The Gresham facility boasts 100,000 ft2 worth of clean room space and supports 250 nm, 180 nm, and 110nm CMOS and BCD technologies. The wide range of trusted technologies that ON Semiconductor offers is a distinct differentiation from other suppliers. ON Semiconductor has also been granted Category 1A Trusted Broker and Trusted Design accreditation, enabling the company to offer a fully comprehensive Trusted ASIC solution, by overseeing the trusted design, test, assembly and qualification flows with its Category 1A Trusted partners.
With so much at stake, defense and aerospace sectors must have access to the latest innovative semiconductor technologies without being exposed to sources of interference or obstruction (whether malevolent or otherwise). Through the Trusted Foundry Program it has been possible to combat the potential dangers that the shift of microelectronics manufacturing to unsecure offshore locations unearthed, and attain a trusted supply chain for US military mission critical applications. It has allowed the creation of a safe environment in which the development and fabrication of semiconductor devices for DoD electronic design projects can be undertaken via state-of-the-art technology, while simultaneously eradicating the presence of counterfeit or tampered components from the supply chain and sustaining prolonged acquisition cycles lasting for many years.
