Abstract: During chemical mechanical polishing of a substrate, a signal value that depends on a thickness of a layer in a measurement spot on a substrate undergoing polishing is determined by a first in-situ monitoring system. An image of at least the measurement spot of the substrate is generated by a second in-situ imaging system. Machine vision processing, e.g., a convolutional neural network, is used to determine a characterizing value for the measurement spot based on the image. Then a measurement value is calculated based on both the characterizing value and the signal value.

Abstract: A toothpaste dispensing pen style toothbrush including a toothbrush head assembly, a housing assembly, and an electrical assembly is disclosed. These assemblies in conjunction with one another provide a simple solution to brushing your teeth. The housing assembly includes toothpaste stored therein.
