Used ULTRON SYSTEMS INC / USI UH 108 #293628721 for sale

ULTRON SYSTEMS INC / USI UH 108 is a photoresist equipment, which uses modern lithographic techniques to produce high quality and exact images in the electronics industry. The system utilizes UV light to selectively expose photoresist films on various types of substrates, and requires no additional development steps for the photoresist pattern production process. The unit has a highly balanced output from the UV source and provides a sharper image in the most common photoresist films. Using the patented Spatial Filter at the lamp output helps to reduce the level of diffraction, resulting in higher image sharpness and resolution. In this machine, the Light Distribution for the Focus Alignment is in agreement with SEMI123/SEMI214/SEMI224 standards, with an improved design for Higher Uniformity Lighting on the wafer substrates. The larger field and improved angle control of the optics helps to improve the exposure uniformity on the substrates. The projected photoresist images can easily be inspected by the automated Motorized Automatic Macro Magnifier (MAMM) and optional Position Compensation Accessories (PCA). This will help to effectively reduce the time spent on manual inspection, as well as reduce time spent during substrate exposure. USI UH 108 is designed for high-volume production, and has high-precision, repeatable exposure calibration specifications. The tool calibrates the UV exposure levels over the entire wafer surface and to achieve the desired profile across multiple exposure levels. The results of this calibration process are permanent, as it is based on image data rather than timing. In addition, the asset also includes a Wafer and Film Pressure Control Model, which allows the exposure equipment to be operated under vacuum, constant pressure, or air. This system helps to further improve the uniformity of exposure on the substrates and to reduce any potential exposure misalignment. ULTRON SYSTEMS INC UH 108 is the perfect choice for a photoresist unit for the electronics industry. It provides high-precision, repeatable exposure calibration specifications and a highly-uniform illumination, as well as the option of vacuum, constant pressure, or air exposure. The optional inspection equipment further reduces exposure time, ensuring which increases accuracy and image quality.
