Cimetrix Control FrameworkTM (CCF) 是基于微软.Net技术的设备自动化控制软件框架，该软件不仅为设备制造厂商提供了监督控制和生产控制框架代码，而且完全实现了GEM/GEM300/EDA标准。借助CCF软件平台，软件工程师无需深刻掌握工厂自动化的所有SEMI标准，就能轻松变身为工厂自动化开发专家。CCF软件框架内的工厂自动化模块基于Cimetrix公司的CIMConnect，CIM300，CIMPortal Plus三个独立的软件开发套件（SDK）实现，分别对于实现GEM，GEM300，和EDA标准。全球任意一家300mm的芯片制造工厂都有安装了CIM300软件的设备运行，在支持EDA数据采集的工厂都有安装了CIMPortal Plus软件的设备运行。CCF软件框架将所有工厂自动化的开发工作交给Cimetrix公司来完成，设备软件工程师可以把更多的时间花费在如何设计自己的设备控制软件上。
We encountered an interesting issue when working with semiconductor equipment manufacturing companies. Many excellent software engineers who know equipment control are not very experienced with the GEM, GEM300, and EDA standards. Sometimes after equipment is successfully developed in the laboratory and before the equipment is shipped to the factory, we discover that the equipment did not implement or only partially implemented the required GEM/GEM300/EDA standard. This is especially prevalent when the factory requires the EDA (Interface A) communication interface. Equipment software engineers sometimes do not know how to develop software that fully complies with GEM/GEM300/EDA standards in a short period of time.
For most equipment companies with limited human and financial resources, it is difficult for the company to have the resources to develop their own GEM/GEM300/EDA software. Another issue is that we have found many of the more experienced software engineers are more interested in high-profile internet, gaming, mobile phone apps and other software industries rather than the lower profile semiconductor industry. Although many companies in the semiconductor factory automation software market have provided GEM/GEM300/EDA software development kits (SDKs), software engineers still need to master certain basic knowledge of factory automation to start writing software integration code. Factory automation involves a large number of SEMI standards. For example, the GEM standard has about 450 pages of documents, including E4, E5, E30, E37, E37.1, E172, E173. GEM300 standards have about 280 pages of documents, including E39, E40, E87, E90, E94, E116, E157, E148. The more complex EDA standard has about 480 pages, including E120, E125, E128, E132, E134, E138, E164. For less experienced factory automation software engineers, the integration of automation software can be an extremely tedious and difficult task.
Cimetrix CIMControlFrameworkTM (CCF) is an equipment automation control software framework based on Microsoft .Net technology. This software not only provides equipment manufacturers with supervisory control and equipment control framework code, but also fully implements the GEM, GEM300 and EDA standards. With the help of the CCF software platform, software engineers can easily turn into factory automation development experts without having to master all the factory automation SEMI standards. The factory automation components within the framework of the CCF software are based on CIMConnect, CIM300, and CIMPortal Plus, three independent software development kits (SDKs) from Cimetrix for the implementation of the GEM, GEM300, and EDA standards, respectively. All 300mm chip manufacturing factories in the world have equipment installed which uses CIM300 software. Any factory requiring EDA data collection has equipment installed that uses CIMPortal Plus software. With the CCF software framework, Cimetrix has already done the work of integrating all factory automation into the framework. The equipment software engineer can spend more time on how to develop their own equipment control software.
Under the CCF framework, the underlying API functions of CIMConnect/CIM300/CIMPortal Plus are well encapsulated. Software engineers can easily implement all the GEM/GEM300/EDA standards of the factory host program through the functions or interfaces provided by the CCF framework. An important task in implementing the EDA standard is to create an equipment model that supports hierarchical structures and generate XML data in accordance with standards. In addition, the generated model must also meet the SEMI E164 standard. The equipment model is dynamically generated when the CCF software is initialized. The software engineer needs to do very little to have an equipment control application that is fully compliant with the EDA standard.
The use of the CCF software framework to reduce the difficulty and development cycle of equipment control programs and factory automation programs does not mean that our clients must replace their existing software platforms or stable code that has been tested. CCF is a fully open automation control program framework that provides source code. You can think of CCF as a LEGO toy that has been put together. Users can either integrate their own code modules into CCF or select some of the CCF functional modules and transfer them to their own framework. Our clients can reuse the factory automation modules (including GEM/GEM300/EDA) in CCF in their own program frameworks. While ensuring that all SEMI standards for factory automation are fully complied with. The impact on the user's existing programs is minimal.
Thanks to the complete openness of the CCF framework, like LEGO bricks, software engineers can easily enjoy the freedom of tailoring the control system framework that they want. It is hard for any company that provides an equipment control software framework program to implement such a rich library of functions.
In the next few years, more and more factories will move in the direction of smart manufacturing. As a result, the demand for data is getting higher and higher. EDA standards are increasingly becoming the factory's mainstream data collection method. CCF will undoubtedly become the best weapon for equipment manufacturers to quickly and completely implement the various factory automation standards.
