A planar light wave circuit may be formed with a pair of waveguides arranged in close proximity to one another. Some embodiments employ both conformal ion implantation and conformal deposition of dopant containing films, and in those embodiments in which the dopant containing film is a pure dopant, the ion implantation and film deposition can be performed simultaneously. The data produced by the testing systems are automatically analyzed and compared with patterns on which the neural network was previously trained, and clinical diagnoses for pathological conditions are thereby suggested to the respective clinician for each patient. If the extracted voice pattern is contained in the list, a determination is made whether a stored phone number matches a received phone number. The porous member adheres to the semiconductor wafer by suction and fixes the wafer in place.
