    Abstract: A method and apparatus measures the presence of total residual oxidant species in aqueous environments.

The apparatus can be a sensor having four electrodes—a reference electrode, a working electrode, and two auxiliary electrodes. The fourth electrode, i.e., the second auxiliary electrode, can be used to generate ionized water near and in contact with the working electrode. The ionized water can clean the working electrode to minimize effects due to scaling or biofilm formation. As such, the working electrode does not need the capability to clean itself. Thus, other elements, originally believed to be unsuitable for use in saline aqueous environments, can be used for the electrodes, for example, gold.

The process includes electroplating a Se material layer, which has an amorphous micro-structure and which exhibits high electrical resistivity, on a workpiece and subsequently annealing the Se layer. Annealing process transforms the amorphous structure of the Se layer into a crystalline structure which is conductive. After the annealing, another Se layer can be electroplated onto the annealed Se layer. The electroplating and annealing steps can be repeated until the desired Se layer thickness is reached.

    Abstract: A substrate processing apparatus comprises an applying part for applying droplets of cleaning solution onto a substrate, a ring-shaped induction electrode located close to an outlet of the applying part, and an applying part moving mechanism for moving the applying part. In the substrate processing apparatus, electric potential difference is generated between the induction electrode and a cleaning solution tube in the applying part, positive charge is induced on the cleaning solution, and the substrate is cleaned by the droplets of the cleaning solution, whereby the substrate can be suppressed to be negatively charged during cleaning. Concurrently with movement of the applying part and application of the cleaning solution, the electric potential difference is controlled on the basis of the characteristics of charging of the substrate and relative position of the applying part to the substrate. It is possible to improve uniformity of distribution of electric potentials on the substrate.
