Used MIDAS MDE-20000 #9215486 for sale

MIDAS MDE-20000 is a wafer stepper used in photolithography to image a variety of 3D shapes and structures onto a substrate. The device is composed of two distinct components; the projection unit and the wafer stage, and utilizes ultra-violet (UV) photolithography to define the shapes on the substrate. MDE-20000 projection unit is capable of defining structures with a resolution of 0.25 micron (250 nm) with an accuracy of up to 5 microns (5,000 nm). The projection unit houses a scanning optical equipment and a laser source which is used to project the desired shape pattern onto the wafer. The projection unit's optics are designed to provide an intensity uniformity of better than 0.1% over the entire imaging area, and can be used to project exposure fields up to a maximum diameter of 20 mm. MIDAS MDE-20000's wafer stage allows for the movement of a wafer or substrate beneath the projection unit. The wafer is secured to a two-dimensional motor-driven stage and can be adjusted to move along both the X and Y axes. The wafer stage also includes a closed-loop motor control system which is used to ensure that the wafer is always in the correct position for imaging. The position of the wafer stage can be measured with an accuracy of up to 0.5 micron (500 nm). MDE-20000 also has a comprehensive set of safety features to protect both users and the device from potentially damaging radiation. These features include a set of sensors that monitor the unit's temperature and light intensity to ensure the users safety, along with a safety shutter and an emergency power cut-off machine. MIDAS MDE-20000 is a powerful and reliable wafer stepper that is suited to a variety of photolithography applications. With its combination of imaging resolution, accuracy, and safety features, MDE-20000 is an ideal solution for high-precision imaging needs.
