Used KARL SUSS / MICROTEC MJB-4 #293751563 for sale

KARL SUSS / MICROTEC MJB-4 is a mask aligner developed by MICROTEC. It is a full-field, high-precision contact alignment equipment designed for non-uniform substrates. It is comprised of a precise movable x/y stage and an aligning objective lens, allowing for accurate micropattern alignment of photoresist during lithography operations. The system has two major components: the master bracket and the pair of alignment objectives. The master bracket holds substrates in place with mechanical clamps, and the alignment objectives provide precise alignment of one originally aligned lithographic reticle. The mechanical clamps provide stability while minimizing alignment distortion due to high clamping pressure. The objectives contain precision adjustable lenses to provide the necessary alignment accuracy. The precision of MICROTEC MJB4 is achieved by using a proprietary kinematic unit, which consists of extremely flat, parallel surface glass plates controlled by adjustable tangential force springs. The accuracy of the pressure compensation machine allows for extremely precise exposure of micro-patterns. The alignment objectives are equipped with a velocity dependent electronic focus drive, allowing for fast and precise alignment of the substrates. KARL SUSS MJB 4 features a full-field exposure tool, allowing exposure of large substrates with ease. The asset is capable of submicron resolution, both in the x-axis and in the y-axis, ensuring accurate exposure of patterns. The support fixtures fittings provide a wide accommodation range for substrates with different shapes, sizes, and material content. This mask aligner is ideal for organizations involved in microelectronics, optoelectronics, flat panel display technologies, and other precision lithography applications. It offers superior accuracy and repeatable performance, capable of delivering top quality results in full-field exposure operations.
