Photo Repeater

Photo repeaters are a type of photolithography equipment used in the semiconductor industry to pattern thin films on a substrate. They are specialized tools that use light to transfer a pattern from a photomask to a semiconductor wafer. The process of photolithography involves creating a pattern on a photomask, which is a transparent plate that contains a circuit layout. The photomask is placed in the photo repeater and light is projected through it onto the surface of the semiconductor wafer. The light is used to transfer the pattern onto a layer of photoresist on the surface of the wafer. Photo repeaters use a variety of optical components, including lenses and mirrors, to focus and align the light and photomask onto the wafer. They typically have high resolution and accuracy, allowing them to create very fine patterns on the surface of the wafer. There are several different types of photo repeaters available, including contact and proximity printers. Contact printers use physical contact between the photomask and the wafer to transfer the pattern, while proximity printers use a gap between the photomask and the wafer. Overall, photo repeaters are an essential tool in the semiconductor industry for creating the complex patterns required in the manufacturing of integrated circuits and other electronic devices. By using photo repeaters to accurately transfer patterns onto semiconductor wafers, manufacturers can ensure the quality and performance of their products.
