Used KARL SUSS / MICROTEC MJB-3 #293685973 for sale

KARL SUSS / MICROTEC MJB-3 is a high precision mask aligner for the fabrication of thin film microelectronic circuits. It is suitable for applications ranging from contact masks to high resolution patterning of thin films on substrates. MICROTEC MJB3 precision aligner is designed to align masks in the presence of high frequency electromagnetic radiation fields such as those used in MIL-STD-882, Automated Pattern Transfer Systems. KARL SUSS MJB 3 is equipped with an Electromagnetic Radiation Shielding & Chamber, an electromagnetic alignment equipment, a sophisticated motion control system, an X-Y-Z motion stage, and an in-vacuum optical alignment unit. The Electromagnetic Radiation Shielding & Chamber is implemented using advanced materials technology and its configuration allows for the shielding of intense radiation fields. The electromagnetic alignment machine uses an electromagnetic field to align the mask with the substrate. This tool also includes an auto-adjust mechanism to ensure that the masked film is accurately placed on the substrate with high accuracy. The sophisticated motion control asset ensures accurate registration of the mask and the substrate. Its components include a proportional-integration-derivative (PID) servo loop, a sophisticated programmable digital signal processing processor, and a high-speed state machine controller. The X, Y, and Z motion stages are employed for moving the mask, substrate, and optics around in a finely controlled manner to ensure matched registration of the mask and substrate for accurate alignment. KARL SUSS / MICROTEC MJB 3's in-vacuum optical alignment model utilizes Laser Diffraction Spectroscopy (LDS) and reflective illumination to detect nearly microscopic positional affinities between substrate and mask registration points. The LDS equipment is based on optical measurements and has a high accuracy as well as high speed. The reflective illumination fills the gap between a standard camera and the LDS system, providing both high resolution imaging and detection of features at the subpixel level. MICROTEC MJB 3 precision aligner is designed for use within cleanroom environments and can be operated with the utmost safety when precautions are taken and the unit is used in compliance with instructions provided. KARL SUSS MJB3 mask aligner is a reliable and highly accurate machine for the fabrication of thin film microelectronic circuits.
