Used ULTRATECH 900 #9233006 for sale

ULTRATECH 900 Wafer Stepper is a fully automated stepping equipment designed to produce repeatable microbridges and other patterned features on wafer surfaces with a minimum of variability. 900 is capable of operating at 9nm resolutions and has been widely used in the semiconductor industry for rapid prototyping and volume production runs. ULTRATECH 900's 9nm resolution enables extremely precise and repeatable patterns to be created on wafer surfaces. As a stepping system, it is capable of bridging very small gaps between islands or other targets on the wafer, making it well-suited for producing narrow interconnects or channels. 900 is designed to be highly reliable, allowing for continuous production runs without concern for device errors or other costly interruptions. In terms of optics, ULTRATECH 900 is equipped with an automated imaging unit which provides for faster, more accurate placement of targets on the wafer surface. An additional feature of 900 is its auto-tuning of step sizes and laser power settings which allows for greater control over process variance with each patterning run. ULTRATECH 900 also has a built-in data collection and analysis machine, which allows for easy monitoring of all data related to the stepping process. 900 is equipped with a carousel stage that is driven by an alignment tool with high accuracy, which allows for the rapid indexing of wafer targets throughout the production process. Additionally, ULTRATECH 900 is configured with a dual-beam laser, which can be used to produce complex shapes and features, such as cut-outs and T-junctions. 900 also includes an automated load and unload station which facilitates faster job changes. ULTRATECH 900 is also designed for low maintenance and ease of use, with a suite of tools for monitoring and adjusting process parameters. In addition, 900 comes with a full range of safety features, including programmable current and voltage limits, laser pulse monitoring, and beam interruption detection. These features help to protect against power anomalies, preventing costly asset damage and production disruptions. ULTRATECH 900 is an excellent stepping model for customers looking for high speed, accuracy, and repeatability in their wafer processing. With its sophisticated imaging equipment, dual-beam laser, automated carousel stage and alignment system, as well as automated load and unload station, 900 is able to produce repeatable microbridges and other features on the wafer surfaces with a minimum of variability.
