American-made lasers for semiconductor manufacturing, inspection, masking, plus morePower Technology
Lasers are used in the manufacturing of semiconductors in several ways. One of the main uses is in lithography, but other applications such as inspection, masking, dicing, annealing, and others are equally important to the innovation and further development of high-tech devices.
Laser lithography is a process that uses lasers to create patterns on a photoresist material, which is then used to create patterns on a semiconductor substrate, such as a silicon wafer. This process is commonly used in the manufacturing of semiconductor devices, such as computer chips and other electronic components.
In laser lithography, a laser beam is focused onto the photoresist material using a series of lenses and mirrors. The laser beam is modulated using a digital micromirror device (DMD) or other optical device, which allows the laser to create very precise patterns on the photoresist. These patterns are typically created using a series of closely spaced lines, with feature sizes as small as a few microns.
Once the pattern has been created on the photoresist, the photoresist is developed using a chemical process, which exposes the underlying semiconductor substrate. The exposed areas of the substrate are then etched using a chemical process, which creates the desired pattern on the semiconductor.
Another irreplaceable manufacturing technique involving lasers is seen in semiconductor masking. This occurs when a laser is used to project a pattern onto a photoresist material, which is then used to create a mask for the semiconductor device. The laser beam is typically focused onto the photoresist using a series of lenses and mirrors, and is modulated using a digital micromirror device (DMD) or other optical device. This allows the laser to create very precise patterns on the photoresist, with feature sizes as small as a few microns.
Further applications include semiconductor inspection – where lasers are used to examine the quality of the patterns created on the photoresist. This typically involves shining a laser beam onto the pattern and measuring the intensity and phase of the reflected light. By analyzing the reflected light, it is possible to determine whether the pattern is free of defects and meets the required specifications.
Lasers are also used in the etching process, where they are used to remove material from the surface of the substrate to create the desired patterns and features. This can be done using a focused laser beam to remove material selectively, or by using a broader beam to remove material over a wider area.
In addition, lasers are used in the process of doping, where impurities are added to the semiconductor material to create the desired electrical properties. This is typically done using a focused laser beam to add the impurities to specific areas of the substrate.
Recent geopolitical events and market disruptions have brought a spotlight onto the idea of manufacturing semiconductors and high-tech CHIPs in America, instead of the current total reliance on importing and international manufacturing. In fact, Power Technology, Inc hosted and sponsored the Arkansas Semiconductor Business Leaders Conference, where important decision-makers from the photonics, academic, government, and manufacturing industries met to develop a plan and discuss the implications of the CHIPS and Science Act on Arkansas and extension, our customers across the globe. You can view the on-demand version of that webinar below.
Maintaining a stable domestic supply chain in manufacturing is important for a number of reasons. First and foremost, it helps to ensure that the manufacturing process is efficient and cost-effective. By sourcing materials and components from within the country, manufacturers can avoid the costs and complications associated with importing these items from overseas.
Additionally, a stable domestic supply chain can help manufacturers to respond quickly and effectively to changing market conditions. With a local supply of materials and components, manufacturers can adjust their production processes in real-time to meet changing demand or take advantage of new opportunities. This agility can be critical to maintaining a competitive edge in today’s fast-paced global economy.
Power Technology Inc’s advanced laser manufacturing, design, and distribution center is located just outside of Little Rock, Arkansas, United States. Arkansas is located in the central part of the United States, which makes it an ideal location for manufacturing businesses that need to serve customers across the country. The state is home to a number of major highways and transportation hubs, which can help manufacturers get their products to market quickly and efficiently. Additionally, Arkansas has a low cost of living and a business-friendly environment, which can make it an attractive location for manufacturers.
