Problems solved by technology

Another disadvantage is that the paddles may interfere with the uniformity of the electric field generated by the electrodes, which further affects the uniformity of application of material to or removal of material from the workpiece
A further disadvantage of the foregoing structure is that the container may also contain magnets located near the workpiece in order to control the magnetic direction of the material applied to the workpiece
When the electrodes are removed from the container for maintenance or replacement, this is difficult to do without interfering with and / or damaging the magnets

Embodiment Construction

[0039] As used herein, the term "microfeature workpiece" or "workpiece" refers to a substrate on which and / or in which microelectronic devices are integrally formed. Typical microdevices include microelectronic circuits or components, thin film recording heads, data storage elements, microfluidic devices, and other products. Micromachines or micromachined devices are included within this definition because they are fabricated with techniques very similar to those used in integrated circuit fabrication. The substrate can be a semiconductor (such as a doped silicon wafer or a gallium arsenide wafer), a non-conductor (such as various ceramic substrates) or a conductor. In some cases, the workpiece is generally circular, while in other cases, the workpiece has other shapes, including rectilinear shapes.

[0040] In the following, several embodiments of integrated tools for wet chemical processing of microfeatured workpieces are presented for depositing metal or electrophoretic re...

Abstract

A tool with installation module is disclosed. The installation module has an aligning system and comprises a positioning element for precise positioning the reactor and the workpiece transferring device which moves the workpiece into and out of the reactor. The module is fixed at the relative position between the positioning elements of the reactor, therefore, the workpiece transferring device do not need to be re-marked when the reactor is detached and changed by another one. The reactor includes an agitator for agitating the treating fluid on the treated surface of the workpiece. The agitator, the reactor and the electrodes in the reactor is configured to reduce the probability of generating electric shadow by the agitator, and the 3-D effect to electric field, when the beater and / or workpiece receiver move relatively, is considered.
