Lam Research’s Dextro cobot boosts semiconductor production efficiency
- Lam Research Corp. has launched Dextro, its first collaborative robotic arm, designed to carry out essential maintenance tasks on semiconductor wafer fabrication equipment. Dextro's precision in tool maintenance is significant for chipmakers to continuously produce at a nanoscale with accurate reassembly at the subsystem level. This leads to less variability and higher yield in production. Within a fab accuracy is vital, and Dextro has been designed to minimize tool downtime and production variability. Nearly every advanced chip built today is made using Lam technology and having Dextro at the fab can enhance yield, even down to the sub-micron level.
- Fabs continue to grow in size, geographic diversity, and equipment complexity, which makes it vital for chip makers to make their processes more efficient by increasing automation as the number of semiconductor positions worldwide continues to outpace the availability of skilled engineers. Precision maintenance is critical as accurate reassembly of subsystems translates to the bottom line. Achieving first-time right (FTR) saves time and cost, repeatable maintenance can reduce waste leading to higher yield in production.
- According to Young Ju Kim, the head of the Memory Etch Technology Team at Samsung Electronics, "error-free maintenance by Dextro helps drive improvements in production variability and yield. This is an exciting milestone in Samsung’s journey to the autonomous fab."
- Dextro is a mobile cart that is guided and docked to a piece of equipment, then operated remotely by a fab engineer or technician. The cart contains the cobot’s control systems and much of the core technology. Within a fab, Dextro's flexibility means it can be repositioned as the process equipment is taken offline for maintenance, making it far more cost-effective than a dedicated cobot for each process tool.
- Dextro cobot arm is made using the Universal Robots' UR5e cobot arm with a reach of 850mm (33.5in.), a payload of 5kg (11lb) and equipped with a quick change end-of-arm wrist. It can accurately install and compress consumable components with over twice the accuracy of manual application, eliminates chamber temperature deviations, which may take a tool out of production and impact die yield.
- Lam Research’s portfolio also includes the Lam Equipment Intelligence process tools with autonomous calibration. It includes the Equipment Intelligence Services that use data, machine learning, artificial intelligence, and Lam domain knowledge to achieve better productivity outcomes.
- Dextro is currently being used in Advanced wafer fabs worldwide and will expand to support more Lam tools beyond Flex G and H series dielectric etch tools in 2025.
- According to Bob O’Donnell, president of TECHnalysis, "Dextro can automate tedious, time-consuming, and often intricate cleaning and maintenance tasks on chip fabrication equipment so that manufacturing output can be maximized. It offers a huge benefit for companies that choose to deploy it."
- Chris Carter, group vice president of the Customer Support Business Group at Lam Research, said, "Dextro is an exciting leap forward in semiconductor manufacturing equipment maintenance. Built to work side by side with fab engineers, it executes complex maintenance tasks with precision and repeatability that are beyond human capability alone, enabling higher tool uptime and manufacturing yield. It is a powerful addition to Lam’s extensive portfolio of tools designed to help chip makers optimize their fabs for cost and productivity."
- As fabs grow in size, geographic diversity, and equipment complexity, chip makers need to optimize their effectiveness of human engineers by increasing automation, especially since the number of semiconductor positions worldwide continues to outpace the availability of skilled engineers.
- Precision maintenance is crucial in tool maintenance since accurate reassembly of subsystems translates into bottom line results, Lam Research revealed. Achieving first-time right saves time and cost as repeatable maintenance can also reduce waste associated with consumable parts, labor, and production downtime. The result is less variability and higher yield in production.

Smart TVs spy on viewing habits even when used as monitors
- Smart TVs are tracking what you watch—even when you use them as external screens.
- This tracking is done through Automatic Content Recognition (ACR) technology that captures screenshots or audio of the content on the screen.
- Smart TV manufacturers collect and transmit data frequently, regardless of how the TV is used.
- Privacy settings on smart TVs can be adjusted to prevent data collection, but ACR is enabled by default.

Smart windows could be the next big thing in renewable heating
- Smart windows can help to control energy transfer without compromising on transparency and daylight. The majority of windows on the market are electrochromic, requiring electricity to function. This makes them difficult to use in remote locations without consistent access to electricity and users need to install an alternative like solar panels to make the windows carbon neutral. To overcome these limitations, researchers have developed thermochromic windows. These windows have the potential to be as efficient as electrochromic windows in blocking infrared; they can progressively tint darker as outside temperatures rise, which means you can have more transparent windows than those on/off EC products.
- The vanadium dioxide layers in today’s thermochromic glass reflect infrared light fully only at around 67°C, which is much hotter than even the all-time highest temperature in the world. Researchers are developing coatings to improve the glass efficiency. The University of Exeter’s Environment and Sustainability Institute has been testing different coatings for thermochromic windows, identifying the one that can effectively reduce infrared light at more realistic outside temperatures. The research includes enabling windows to work as an insulator when temperatures are low, store energy, and to be useful in cold climates.
- Smart windows should bring benefits in terms of carbon reduction and energy efficiency. Emissions from buildings released by air conditioning, heating, and ventilation systems can be reduced by 60 to 70% and heat loss from rooms is reduced by approx 40%. Windows currently on the market such as electrochromic windows are projected to increase by 60% by 2028. Smart windows could also be used in airplanes and cars.
- EC windows operate via electricity, thereby causing inconvenience in remote locations and the grid’s absence. With the right research success and policy support, the next-generation smart windows could bring significant improvements to carbon emissions of buildings. In summary, it is difficult to predict when the thermochromic products will come to the market, but in 5-10 years the research may bring smart windows to colder countries in the daytime and night. This may reduce the number of radiators from 5 to 2 in apartments.
