TUNABLE PLASMA EXCLUSION ZONE IN SEMICONDUCTOR FABRICATION
A tunable plasma exclusion zone in semiconductor fabrication is provided. A semiconductor wafer is provided within a chamber of a plasma processing apparatus between a first plasma electrode and a second plasma electrode. A plasma is generated from a process gas within the chamber and an electric field between the first plasma electrode and the second plasma electrode. The plasma is at least partially excluded from an edge region of the semiconductor wafer by a plasma exclusion zone (PEZ) ring within the chamber. The plasma may be tuned toward a center of the semiconductor wafer by electrically coupling an electrode ring of the PEZ ring to a voltage potential.
SUBSTRATE PROCESSING APPARATUS
Provided is a substrate processing apparatus. The positions of a first electrode and a second electrode are adjusted in advance in consideration of differences in coefficients of thermal expansion so that a short circuit created by contact between the first electrode and the second electrode is prevented even in the case in which the first electrode and the second electrode are thermally expanded during processing. Even in the case in which the first electrode and the second electrode are thermally expanded due to an increase in temperature during processing, a short circuit between the first electrode and the second electrode can be prevented, and the uniformity of a thin film can be maintained in the substrate processing apparatus for processing a large substrate.
Charged Particle Microscope and Method of Imaging Sample
The present invention provides an electron microscope and an observation method capable of observing secondary electrons in the atmosphere. In detail, a charged particle microscope of the invention includes: a partition wall that separates a non-vacuum space in which a sample is loaded from a vacuum space inside a charged particle optical lens barrel; an upper electrode; a lower electrode on which the sample is loaded; a power supply for applying a voltage to at least one of the upper electrode and the lower electrode; a sample gap adjusting mechanism for adjusting a gap between the sample and the partition wall; and an image forming unit for forming an image of the sample based on the current absorbed by the lower electrode. The secondary electrons are selectively measured by using an amplification effect due to ionization collision between electrons and gas molecules generated when a voltage is applied between the upper electrode and the lower electrode. As a detection method, a method is used which measures a current value flowing in a substrate.
