Used KARL SUSS / MICROTEC MA 4 #293815168 for sale

KARL SUSS / MICROTEC MA 4 is a mask aligner designed to offer operators both high accuracy and flexibility to give the highest quality results. It is an advanced wafer stepper which uses a stepping motor to incrementally adjust the probe's position across a wafer. The alignment is accomplished by viewing a set of chrome-on-quartz patterned reticles under a microscope and making small adjustments by activating the stepper to ensure alignment. MICROTEC MA 4 features a unique optical system which includes a 3-magnification objective lens, a movable precision stage, and a triplet Korr objective lens for accurate alignment of the mask to the wafer. It also features a long working distance for long working ranges and minimal focus adjustment. KARL SUSS MA-4 is equipped with a modern control system for fast and accurate alignment. It includes a touch-sensitive display that provides a range of operation parameters to the user, along with user-friendly application software for creating and operating step and repeat operations. The system utilizes a dedicated 32-bit alignment tool to allow the user to make small adjustments to the mask pattern with micrometer-precision accuracy. MA-4 offers a wide range of magnification options as well as large reticle size options, making it suitable for many applications. It can easily handle a variety of masks, ranging from blind vias, to encapsulated electrodes, to full MEMs devices. MICROTEC MA-4 is a cost effective stepper, offering high precision and repeatability, making this an ideal choice for many businesses in the semiconductor industry. It is a versatile, reliable machine that helps users achieve accurate, high-quality results with repeatable precision.
