Industry News, Trends and Technology, and Standards Updates

Today I would like to give an update on SEMI Standards activities in Korea. 

Though it began in 2024, our group does not have an official name yet; for the time being, we simply call it the “Autonomous Fab Working Group.”

As you can infer from the name, the goal is to establish a SEMI standard for the Autonomous Fab. Though this may represent a challenge for some of the major semiconductor manufacturers, given their presence in the global market, it is natural that these companies, like Samsung and SK hynix would need to have a vital role in this initiative.

A little history is appropriate at this point. This activity first began with a forum meeting during SEMICON Korea 2024 last February. Samsung’s executive vice president held a keynote session as a part of the SEMICON Korea conference, and it ignited the participants’ imaginations to suggest ideas for a new SEMI standard. After SEMICON, SEMI Korea organized a follow-on meetings to further develop these ideas. Several meetings were held, and we agreed on the main themes and specific focus areas for a number of sub-groups.

I joined as a representative of PDF Solutions, Cimetrix Prdoucts. Samsung and SK hynix sent 5-7 engineers each. Other Korean equipment suppliers and software companies, such as Miracom, Wonik, Global Zeus, Doople, and BISTel, joined as well.

The following summary of a recent meeting provides additional insight into this effort:

• Working title: Autonomous Fab Working Group
• Purpose: Develop Autonomous Fab standard to achieve better competence and innovation, maximize the efficiency and quality of semiconductor manufacturing processes
• Related activities
  • Standardization and authentication of Autonomous Fab technology
  • Sharing information for cooperation
  • Establishing active relationships between industry and academia
  • Prediction and response of future technologies
  • Developing an educational program to train new industry people

We plan to have another meeting in July to elect a co-chair for the main working group and fill the other leadership positions.

As many know, Samsung and SK hynix are big influencers for this activity. Sharing technology and ideas can be difficult because of sensitivities. However, with SEMI’s guidance, we believe we can achieve a useful level of consensus for a new standard in the near future.

The six steps for the first approach are:

1. Share common points and goals
2. Choose main themes
3. Derive subitems from #2
4. Set priorities
5. Perform steps for standardization
6. Complete subitems

With this guidance, our first decision was to set up two internal subgroups and assign each their area of work.
Briefly, one is for hardware and one for software. The two groups and subjects are,

1. PM Automation sub-group: Factory footprint & area, Transfer robots, safety, etc.
2. Data & Traceability sub-group: Automated data handling, version management, security, etc.

In addition to the above, all the members agreed that if we have more hardware companies join, such as robot, EFEM etc., it will be an abundant discussion, therefore, SEMI will invite these companies to join at the next meeting.

It has been great to see all of these companies come together and work toward the same goal.

Our next meeting will be on July 17^th (KST). We hope to see everyone there!

Have you experienced a lack of storage space on your equipment?

There can be many reasons for this, and one of them is a lack of space for saving logs.  

One of our Cimetrix CIMConnect customers had this issue and asked if there is a way to add storage to their tool. The engineer commented that there are no available USB slots on their equipment computer. Therefore, he got permission to add a network drive to their system.

How to configure an external network drive for CIMConnect logging

1. Connect an external storage device to the network and you may see it in your File Explorer.
2. Run CIMConnect Control Panel
   1. Go to the equipment tab (“Equipment1” in this view)
   2. Go to “Logging Configuration” under “Equipment” menu.
   3. Click on the folder icon next to the “Directory” text box. 
   4. In the “Browse For Folder” window, find your network drive. 
      
      Here’s tricky part: you may find one under your network, not a mapped one.  It will give an absolute path name, such as “\\RT-AX56U-83E8\Cimetrix_Ian\CIMConnect Logs”
3. If you still cannot see any log files created in that network drive directory. 
   In this case, please follow the steps below to register EMService as a COM Local Server. 
   
   1. Open Windows Command Prompt as an Administrator.
   2. Type “EMService.exe /RegServer” (without quotation marks) and hit Enter.
   3. Restart your EMService: go to Windows “Services” and select EMService then click “Restart”.
      

These steps set a network drive as your extended CIMConnect storage.

To Summarize:

1. Connect an external drive to your network.
2. Use CIMConnect Control Panel to find and set up the added drive. Don’t forget to configure one in the network, not a mapped drive.
3. Register CIMConnect’s EMService as your COM local server.
4. Restart EMService and enjoy the extra storage.

As I mentioned at the beginning, this is a good solution for those who do not have sufficient storage in their existing equipment control system. It is usually difficult to replace the entire PC on your equipment, but external storage can be as simple as I described in this posting.
