Used HITACHI DM 421P #9396134 for sale

HITACHI DM 421P is an advanced model ultraviolet etcher/ashers designed for ultra-fine microfabrication applications. DM 421P is a high-speed etcher/asher with a variable speed motor, making it well-equipped for a wide range of microfabrication projects that require precise process control. With its 8-inch etch and ash chamber and high resolution, HITACHI DM 421P is also an ideal choice for a wide variety of series production projects. At the heart of DM 421P is an adaptive scanning equipment that offers precise and repeatable results by automatically adjusting etch and ash cycles to ensure uniformity in each component of your microfabrication work. HITACHI DM 421P also features a two-stage pump system that reduces pressure oscillations during etching and ash cycles, thereby increasing operational efficiency. DM 421P also offers a fast-start feature that allows for quick setup and reduced cycle times when beginning new projects. Additionally, HITACHI DM 421P provides the flexibility to switch etching and ashing modes halfway through a project without any penalties. DM 421P also features advanced safety features that make it suitable for use in occupied workspaces. It has a three-stage unit for preventing accidental process power interruptions and also features a vacuum locks machine that eliminates the possibility of chemical spills into the workspace. HITACHI DM 421P also offers a unique refractive indexing tool that allows for precise part placement in the chamber and in the sample holder provided. In terms of protective features, DM 421P is designed so that the etcher/ash chamber is heated separately from the sample holder and other components, allowing for a consistent temperature throughout the etch/ash cycle. Additionally, an ultraviolet radiation safety asset is integrated into HITACHI DM 421P to ensure that the operator and any adjacent personnel are safely protected during the process. An audit trail feature also allows for the recording of process parameters for review or reports. In conclusion, DM 421P is an advanced microfabrication etcher/asher with a myriad of features and benefits designed for both short and long-term production projects. With its location and refractive indexing model, precise etch/ash process cycle, and safety features, HITACHI DM 421P is designed to provide decades of reliable, uniform, and high-quality results.
