N363562 · 2026-08-10 — The tariff classification of a semiconductor photolithography wafer stage module from the Netherlands
The product in question is the Wafer Stage Module type NXE MK 1 (Wafer Stage), a unit of the ASML NXEExtreme Ultraviolet (EUV) semiconductor photolithography system. The Wafer Stage is a machine orapparatus that positions a silicon wafer during metrology and exposure (printing circuit patterns onto thewafer). It is comprised of a large rectangular box-like structure containing a magnetic levitation base tosuspend and propel two integral wafer tables (aka chucks or wafer chucks) without physical contact. Onewafer table holds and positions a silicon wafer under a metrology unit which measures…
N336802 · 2023-12-21 — The tariff classification of a wafer handling module from the Netherlands
In a teleconference with this office on December 15, 2023, you provided additional information, and supplementary documentation thereafter. As imported, the wafer handling module will consist of three functional units: the FOUP (front opening unified pod) loading dock, the atmospheric wafer handler, and the vacuum wafer handler. The function of the subject wafer handling module is to deliver silicon wafers from outside of the EXE 5000 to the wafer tables of the wafer stage (a separate modular assembly not imported with the wafer handling module), and then to remove each wafer after exposure…
N282620 · 2017-02-15 — The tariff classification of valves for semiconductor manufacturing from Switzerland.
The importation consists of three valves used exclusively in semiconductor manufacturing. You state that these valves are all designed and manufactured specifically for customers in the semiconductor industry. Part Number 09040-PE44-AB01, an isolation gate valve, is used exclusively on semiconductor abatement tools to neutralize/dissipate toxic gases. The valve is installed inside the gas abatement cabinet and over an oil-free vacuum roughing pump. This valve is used on the Atlas TPU gas abatement system, which is considered the semiconductor industry’s standard abatement system for chemical…
N275956 · 2016-06-03 — The tariff classification of Wafer Loaders from Japan
The three different models of wafer loaders are AL6150, AL86 and AL86180. They are part of the AL120 wafer loader series. Models AL86180 and AL86 can accommodate wafer diameters of 6 inches and 8 inches. Model AL6150 can accommodate wafer diameters of 6 inches. At various times, the wafer loaders will undergo special function changes where the overseas factory will make special sensors or robotics to accommodate specific wafers as requested by the customer. However, the functionality of each wafer loader remains the same which is to automatically transfer semiconductor wafers from a cassette…
N242843 · 2013-07-05 — The tariff classification of Custom Precision Positioning Stages from Switzerland
, you requested a tariff classification ruling. The Custom Precision Positioning Stages are designed for use in electron beam microscopy semiconductor equipment which is loaded by an automated robotic wafer loader. The stages physically position 300mm semiconductor wafers under the beam of electrons or other optic so that the wafers’ surfaces down into the sub-micron range can be measured. The stages perform no measuring function, only a positioning function. The stages contain linear servo motors, imbedded frameless rotary servo motors, position feedback devices called encoders,…
