Used KARL SUSS / MICROTEC MA 45 #293748730 for sale

KARL SUSS / MICROTEC MA 45 is a precision mask aligner widely used in the fabrication of integrated circuits. MICROTEC MA 45 is composed of a highly accurate six-axis micropositioner, an optics equipment, and a light source. This combination of components is used to precisely align and expose photoresist patterns on a silicon wafer. The six-axis micropositioner is the heart of KARL SUSS MA-45. This consists of a platform that can move in three linear directions and three angular directions. The micropositioner is driven by precision-engineered motors and separated stages for each axis. This allows for highly accurate exposure and alignment of photoresist patterns down to the nanometer level. The optics system of KARL SUSS MA 45 uses a combination of lenses, mirrors and filters to precisely align and expose photoresist patterns on a silicon wafer. A specialized lighting source is used in order to ensure accuracy and exposure consistency. It provides a magnified projection of the photoresist patterning on the wafer's surface. Depending on the model and unit configuration, the optics machine of MICROTEC MA-45 is capable of projection exposure of both positive and negative photomasks in a single exposure process. Using MA 45, exposure and alignment of photoresist patterns can be done in three different modes. Manual mode gives the user full control of the mask aligner, while semi-automated mode allows the operator to specify certain parameters such as exposure time, area of exposure, and dimensions. The automated mode can be used to wholly automate the process, based on pre-programmed parameters. MA-45 is an invaluable digital lithography tool for the modern silicon wafer fabrication process. It is highly accurate, efficient, and easy to use, making it a popular choice for companies in the semiconductor industry. This mask aligner is capable of exposing large and intricate patterns on the wafer's surface with the utmost precision and consistency.
