    Abstract: A chemical mechanical planarization system and methods for implementing infrared detection of process state and substrate surface composition are provided. In one example, the chemical mechanical planarization system includes a substrate chuck to hold and rotate a substrate, a preparation head mounted on a preparation carrier, and a conditioning head mounted on a conditioning carrier. The preparation head is configured to be applied against the substrate, overlapping at least a portion of the substrate of an area smaller than the entire surface area of the substrate. The system further includes an infrared sensor positioned over the substrate to sense infrared emissions from the surface of the substrate. Several examples of infrared sensors are provided including single point, scanning, and array infrared sensors. In another example, a method of determining process state and surface composition of a substrate using infrared sensing is provided. During chemical mechanical planarization, an infrared sensor is positioned to sense infrared emissions from the surface of a substrate, and to analyze the infrared emissions to determine process state and to generate a topographical detail of the substrate.

    Abstract: In chemical mechanical polishing apparatus, a wafer carrier plate is provided with a cavity for reception of a sensor positioned very close to a wafer to be polished. Energy resulting from contact between a polishing pad and an exposed surface of the wafer is transmitted only a very short distance to the sensor and is sensed by the sensor, providing data as to the nature of properties of the exposed surface of the wafer, and of transitions of those properties. Correlation methods provide graphs relating sensed energy to the surface properties, and to the transitions. The correlation graphs provide process status data for process control.

    Abstract: A method for converting a slope based detection task to a threshold based detection task is provided. The method initiates with defining an approximation equation for a set of points corresponding to values of a process being monitored (140). Then, an expected value at a current point of the process being monitored is predicted (142). Next, a difference between a measured value at the current point of the process being monitored and the corresponding expected value is calculated (144). Then, the difference is monitored for successive points to detect a deviation value between the measured value and the expected value (146). Next, a transition point for the process being monitored is identified based on the detection of the deviation value (148). A processing system configured to provide real time data for a slope based transition and a computer readable media are also provided.

    Abstract: Methods for fabricating semiconductor structures having LowK dielectric properties are provided. In one example, a copper dual damascene structure (100) is fabricated in a LowK dielectric insulator (102) including forming a capping film (110) over the insulator before features (104) are defined therein. After the copper is formed in the features, the copper overburden (106) is removed using ultra−gentle CMP, and then the barrier is removed using a dry etch process. Following barrier (108) removal, a second etch is performed to thin the capping film. The thinning is configured to reduce the thickness of the capping film without removal, and thereby reducing the K−value of the LowK dielectric structure.
