In today’s climate-conscious world, the semiconductor industry faces a crucial decision: repair or replace? At AESG, we’ve long advocated for strategic repair solutions, not just for cost efficiency but for a compelling reason that affects us all – environmental sustainability.

The Hidden Environmental Cost of Replacement

When facilities opt to replace automated equipment rather than repair it, they contribute to:

• Electronic waste (e-waste) accumulation
• Increased carbon footprint from manufacturing new components
• Raw material depletion
• Additional transportation emissions from shipping new equipment

The Green Benefits of Repair

1. Waste Reduction

   • Each repaired Mag 7 stage or SCARA robot means one less unit in landfills
   • Minimizes packaging waste associated with new equipment
   • Reduces the demand for raw materials

2. Energy Conservation

   • Repair processes typically consume less energy than manufacturing new components
   • Maintaining original OEM specifications ensures optimal energy efficiency
   • Local repairs reduce transportation-related emissions

3. Resource Optimization

   • Extended equipment lifecycle through expert diagnostics
   • Preservation of valuable materials already in circulation
   • Maximized return on initial environmental investment

AESG is offering a new service program to assist in setting up legacy automation in legacy capital equipment.

AESG supports legacy SCARA OEM’s, most of whom have been out of business for years now. During their heyday, each SCARA OEM had their own specific set of commands by which to control the robot, pre-aligner or stage. Of this broad range of commands, their customers, the tool OEM’s, would down select specific commands for their particular application. Traditionally the tool OEM would be the first line of defense in any troubleshooting, but especially when setting up the robot, pre-aligner or stage as these components would set the tool throughput.

A slow teach would mean a less than committed tool throughput. Since many tools warranty structure and performance metrics are based on tool throughput, a slower taught robot would hit the tool OEM in the pocketbook. The fact that the tool OEM’s would not inform the SCARA OEM of the commands they used was secondary to this throughput concern. It just makes a difficult situation all the more problematic.

Since machine tools are designed to perform longer than it takes to pay for them, lots of these legacy tools are still being used today. Unfortunately, most of the tribal knowledge of how a particular tool OEM set up a particular SCARA OEM’s components has been lost to the mists of time. Fortunately for you, AESG has picked up some of this lost knowledge. While we cannot commit to teach the tool for process qualification, we have extensive expertise with the SCARA OEM’s we support and how some of the tool OEM’s use these components. As such, we can assist you in setting up a legacy SCARA or stage in a legacy machine tool. Just ask!

As the market further evolved into the 300mm/12” wafer size, single chamber tools effectively died out sequestering atmospheric SCARA robots to the EFEM and vacuum SCARA’s in the cluster tools. This divergence impacted the value proposition of the atmospheric SCARA as it operated similarly in all EFEM’s for any give process or inspection/metrology toolset. Radically different that the origins of atmospheric SCARA’s that were tailored to a specific capex toolset and thus provided a competitive advantage for the tool OEM. This dummying down of the atmospheric SCARA effectively commoditized this robot and this lead to significant downsizing in the number of atmospheric SCARA OEM’s that supported semicapex.

In the meantime, vacuum SCARA’s evolved as the processing under vacuum complexity increased. While they had limited z-strokes (maybe up to 35mm or so) their handling requirements increased significantly. They became part of the process tool world in that they could negatively impact yields by allowing contaminates to fall onto the end effector of the robot and then instigate cross-contamination between chambers, the transport module, cooling stations and the load locks. And let’s not forget speed, since wafers per hour were the reason for cluster tools coming into being, the vacuum SCARA’s were required to move extremely quickly.

Back in the 2010 timeframe, tool OEM’s wanted the industry to transition to 450mm (18”) wafers. This was primarily because the average sales price for a new 450mm tool was significantly higher than a 300mm tool and this would help the tool OEM’s grow their business to unheard of heights. So the big American tooling OEM’s went to Washington D.C. to convince the federal government to allow for mergers previously prohibited. This would enable the tool OEM’s to achieve the critical mass necessary to launch 450mm toolsets.

But while 450mm failed, the consolidation was never undone. So while competition defined the early days of semiconductor capex, oligarchies defined the new world of capex. This brutal consolation further hammered the SCARA supply chain as with few customers, and few opportunities to define a defensible  value proposition that would drive revenue and profits, the vacuum SCARA’s OEM’s started to die out just as the atmospheric SCARA’s died out 20 years previously.

The push towards 450mm was partially driven by the tooling OEM’s desire to move on from the smaller wafer sizes and only sell new equipment. And never upgrade older tools. But the risk is massive in having an entire ASIC on built on one wafer. The industry can’t accommodate reworks of work in process because so many of the process steps, once done, can’t be undone. So while the tooling OEM’s were focused on 450mm, the semiconductor fabs were focused on using their existing infrastructure of 200mm and 300mm factories.

This gave rise to “chiplets” that are basically ASIC building blocks that enable folks like Qualcomm to build their 5G Snapdragon chipsets at five different semiconductor fabs: three die’s are made at 200mm factories and two dies are made on 300mm tooling. Qualcomm has four of the chips sent to the fifth factory where all five chips are “die stacked” into a package that is then put into a leadframe that will then be encapsulated and given wires that can be then integrated into the end use device.

This radical change in the market place has extended the life of the older tooling that used single chamber tools and atmospheric SCARA’s. Unfortunately, most of the SCARA OEM’s that were used in these tools are no longer in business.  

Understanding the history behind the SCARA enables our AESG techs to better understand how to repair the new models and help to develop innovative ways to continue to repair and rebuild the equipment used today in the Semiconductor industry. Let us know how we can help with your SCARAs today!
