Used DISCO DFD 681 #293749283 for sale

DISCO DFD 681 is a high speed scribing/dicing machine made by DISCO Hi-Tec. It is designed to produce precise photomask patterns on semiconductor substrates used in the fabrication of integrated circuit (ICs). This production quality scribing/dicing machine is equipped with a high accuracy, two-axis positioning stage, precision air bearing spindles, and a cooled stages. Additionally, the machine is equipped with an integrated vision equipment for registration, orientation and continuous inspection of the photomask. The vision system, with its built-in scan camera and edge detector, ensures high accuracy photomask registration. DISCO DFD681 uses a high-powered laser capable of rapidly exposing an entire photomask in a single pass. The exposure area of the laser is continuously monitored for low intensity and high aberrations, which ensures high resolution patterning. The two-axis stage allows for precise placement during processing, and the air bearing spindle provides for the accurate control of the laser. The cooled stages stabilizes the substrate temperature and minimizes thermal stress that can cause substrate warpage. DFD 681 has an efficient automated loading and unloading unit and a closed-loop control that minimizes photomask exposure from ambient light. The machine is easy to program and provides flexibility for a wide variety of processing. It offers a user-friendly control tool with a large memory capacity for storing large data sets. The asset is engineered to manufacture the most complex photomask patterns with the highest accuracy. Its reliable and versatile design meets the demands of production and development lines for the fabrication of cutting-edge integrated circuits. DFD681 is an ideal choice for high volume production of the most advanced photomask patterns.
