Used OAI J500 / VIS #153743 for sale

OAI J500 / VIS is a mask aligner, a type of device used in semiconductor fabrication to transfer patterns from a reticle or reticles onto a wafer surface. It performs the task of mask-to-wafer alignment and exposure. J500 / VIS is an automated precision pattern transfer system used primarily in the production of integrated circuits (ICs). OAI J500 / VIS device is made up of several components, including an optical alignment and exposure head, a reticle stage, a wafer stage, and a controller. The reticle stage is responsible for translating the reticle into a light image on the wafer surface and foradjusting the system for proper alignment. The wafer stage configures the wafer for contact exposure and holds it in place as J500 / VIS aligns the pattern for proper exposure. The optical alignment and exposure head is responsible for directing light from the mask onto the wafer. The controller coordinates the operation of the system components to accurately align and expose the reticle pattern to the wafer. OAI J500 / VIS is capable of high-precision pattern transfer, typically under a 1.5 micron margin of error. This precision is essential in the fabrication of large-scale integrated circuits, such as computer chips, microprocessors, and memory chips. The device can process large wafers at high speed, with a throughput of up to 8 wafers per hour. It is also capable of handling multiple reticles, allowing for greater efficiency and productivity. J500 / VIS is a reliable and cost-effective solution for integrated circuit fabrication. The device is self-contained and requires minimal maintenance, making it an ideal choice for production settings. It is designed for long-term use, with a traditional service life of about ten years. With its high-precision pattern transfer and efficient operation, OAI J500 / VIS is an essential component of the semiconductor fabrication industry.
