Abstract:
PROBLEM TO BE SOLVED: To provide a device which measures the temperature of wafers under exposure.SOLUTION: The device which measures parameters comprises: a substrate; a plurality of sensors 101-105 which measure parameters independently in different positions and are carried to the face of the substrate to be arranged thereon; electric conductors which spread on the surface and are connected to the sensors 101-105 and an electronic process component; and a cover which is arranged on the sensors 101-105, the electronic process component, and the conductors. The cover and the substrate have the same material characteristics to a manufacturing substrate to be processed by a substrate process cell. The present device has the approximately same thickness and/or flatness as that of the manufacturing substrate. A substrate process may be applied to the present device, and one or more parameters may be measured during the process using the present device. On the basis of parameter measurement by one or more sensors 101-105, operation characteristic of manufacturing wafers in the substrate process may be analyzed.
Abstract:
PROBLEM TO BE SOLVED: To provide a substrate processing apparatus and a method thereof.SOLUTION: A substrate processing apparatus may comprise a support structure and a moveable stage including first and second stages 102 and 104. The moveable stage has one or more maglev units attached to the first stage 102 and/or the second stage 104 proximate an edge of the first stage 102. The first stage 102 retains one or more substrates and moves with respect to a first axis that is substantially fixed with respect to the second stage 104. The second stage 104 translates along a second axis with respect to the support structure. In other embodiments, a first motor may maintain a rotary stage at an angular speed and/or accelerate or decelerate the stage from a first angular speed to a second angular speed. A second motor may accelerate the stage from rest to the first angular speed and/or decelerate the stage from a non-zero angular speed.
