Commonly installed in Ultratech wafer steppers used in semiconductor fabrication, MEMS manufacturing, and advanced packaging applications. Semiconductor equipment technicians and field service engineers use this assembly for replacement of worn wafer stage components, preventive maintenance, and restoration of precise wafer positioning and alignment. The assembly includes the 03-20-03371 PCB Stepper Motor and associated drive components; wafer chuck is not included. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5ms9th\" data-start=\"762\" data-end=\"779\"\u003eApplications:\u003c\/h3\u003e\n\u003cp data-start=\"780\" data-end=\"1373\"\u003eThe Ultratech Stepper 01-20-02645 Wafer Chuck Assembly is commonly used in semiconductor wafer fabrication facilities, research laboratories, and electronics manufacturing environments operating Ultratech 4700, 6700, Titan, and Saturn photolithography systems. The integrated stepper motor assembly provides accurate wafer positioning and stage movement required for high-resolution lithographic exposure and repeatable pattern registration. Compatibility should be verified using the original part numbers 01-20-02645 and 03-20-03371 before installation. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"5hg6bl\" data-start=\"1375\" data-end=\"1404\"\u003eTechnical Specifications:\u003c\/h3\u003e\n\u003cp data-start=\"1405\" data-end=\"2050\"\u003e• Brand: Ultratech Stepper\u003cbr data-start=\"1431\" data-end=\"1434\"\u003e• Part Number: 01-20-02645\u003cbr data-start=\"1460\" data-end=\"1463\"\u003e• Associated Part Number: 03-20-03371\u003cbr data-start=\"1500\" data-end=\"1503\"\u003e• Product Type: Wafer Chuck Assembly with PCB Stepper Motor\u003cbr data-start=\"1562\" data-end=\"1565\"\u003e• Function: Precision wafer positioning and stage motion\u003cbr data-start=\"1621\" data-end=\"1624\"\u003e• Motor Type: PCB Stepper Motor\u003cbr data-start=\"1655\" data-end=\"1658\"\u003e• Compatible Equipment: Ultratech 4700, 6700, Titan, and Saturn Wafer Steppers\u003cbr data-start=\"1736\" data-end=\"1739\"\u003e• Mounting: OEM replacement assembly\u003cbr data-start=\"1775\" data-end=\"1778\"\u003e• Installation: Direct OEM replacement\u003cbr data-start=\"1816\" data-end=\"1819\"\u003e• Application: Semiconductor photolithography and wafer handling systems\u003cbr data-start=\"1891\" data-end=\"1894\"\u003e• Note: Wafer chuck not included with assembly\u003cbr data-start=\"1940\" data-end=\"1943\"\u003e• Designed for continuous-duty semiconductor manufacturing operation. \u003cspan class=\"\" data-state=\"closed\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3 data-section-id=\"1cz0398\" data-start=\"2052\" data-end=\"2076\"\u003eCommon Replacements:\u003c\/h3\u003e\n\u003cp data-start=\"2078\" data-end=\"2177\" data-is-last-node=\"\" data-is-only-node=\"\"\u003e• Ultratech Stepper 01-20-03947\u003cbr data-start=\"2109\" data-end=\"2112\"\u003e• Ultratech Stepper 01-20-08947\u003cbr data-start=\"2143\" data-end=\"2146\"\u003e• Ultratech Stepper 01-20-03651\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003c\/section\u003e\n\u003c\/div\u003e","brand":"Ultratech","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":51714363097390,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0940\/0818\/1038\/files\/Ebay_website_image_f0c2354b-9414-4a1e-a7a0-6977b31ea4be.jpg?v=1770424138","url":"https:\/\/plgautomation.com\/products\/ultratech-stepper-01-20-02645-wafer-chuck-assembly-03-20-03371-pcb-stepper-motor","provider":"PLG Automation ","version":"1.0","type":"link"}
