Used SEMITOOL ST 840 #9000640 for sale

SEMITOOL ST 840 is a photoresist equipment designed for automated wet-etch wafer fabrication applications. It consists of a wet-etch system, light sources and chemicals for use in coating, developing, etching and cleaning wafers prior to further semiconductor industrial processes. The photoresist unit provides precise control over the different stages of the fabrication process, such as deposition, etching, light exposure and post-etch cleaning. This ensures that the wafers are manufactured with a high level of accuracy and uniformity. The photoresist machine consists of a single housing enclosing an enclosed wet-etch tool, a light source and a chemical bath. The wet-etch asset up to eight wafers simultaneously and features a pressure regulator, a bulk tank for etchant and a spinning chamber for processing the wafers. The light source is independently adjustable for intensity and wavelength and is used to expose the wafers to remove the desired layers of photoresist. The chemical bath provides a controlled environment for developing, etching and post-etch cleaning the wafers. The photoresist model is designed to allow the user to customize their processing parameters to meet their specific requirements. The light sources can be set to variable intensities and wavelengths, while the etchant, concentration and temperature can be adjusted to create the desired etching profiles. Additionally, the cleaning processes can be customized to include spray, scrub or rinse operations and the wafer surface can be monitored with an automated optical equipment. ST 840 is a robust and reliable machine that is designed to provide accurate and consistent wafer fabrication results. It has been designed with an extensive array of features to ensure that a wide variety of processing needs can be met. The photoresist system is ideal for a wide range of applications such as production of semiconductors, medical devices, and microelectronics.
