Abstract: A method for monitoring consumption of a component, including the steps of emitting a radiation beam onto a first area of the component and detecting a portion of the radiation beam that is refracted by the component. A radiation level signal is generated based at least on a strength of the detected portion of the radiation beam, and a thickness of the component is determined based on the radiation level signal. The thickness of the component is compared to a predetermined thickness value, and a status signal is generated when the comparing step determines that the thickness of the component is substantially equal to or below the predetermined thickness value. When the comparing step determines that the thickness of the component is greater than the predetermined thickness value, the component is exposed to a process that can erode at least a portion of the component.

Abstract: A method of and a structure for controlling the temperature of an electrode (4). The electrode is heated prior to etching the first wafer and both a (temporally) stationary and a (spatially) homogeneous temperature of the silicon electrode are maintained. Resistive heater elements (1) are either embedded within the housing of the electrode (3) or formed as part of the electrode. The resistive heater elements form a heater of a multi-zone type in order to minimize the temperature non-uniformity. The resistive heater elements are divided into a plurality of zones, wherein the power to each zone can be adjusted individually, allowing the desirable temperature uniformity of the electrode to be achieved. Preheating the electrode to the appropriate operating temperature eliminates both the “first wafer effect” and non-uniform etching of a semiconductor wafer.

The apparatus has at least one ultrasonic transducer (2a,2b,2c,2d) configured to emit ultrasonic energy (3) toward an interface between the water (4) and the support member (1) so that the interface generates echo signals, and a data processing unit (11) configured to analyze the echo signals to arrive at a determination as to how well the semiconductor wafer (4) is clamped to the support member (1before semiconductor process is started. A first method ensures that a wafer (4) is securely clamped to a support member before a semiconductor process is started. A second method verifies proper de-clamping of a semiconductor wafer (4) from a support member (1) before the semiconductor wafer (4) is removed from the support member (1) upon completion of a semiconductor process.
