Abstract:
1. A method for determination of depth of depressions which are formed in a mount substrate, comprising: applying an essentially uniform layer of a wetting agent to an area, which includes depressions, on a surface of the mount substrate; recording a time profile of a decrease in weight of the mount substrate during vaporization of the wetting agent; evaluating the recorded time profile of the decrease in weight of the mount substrate to determine a characteristic weight value for the mount substrate in a state in which the wetting agent has vaporized from the surface of the mount substrate and the depressions are filled with the wetting agent; and determining the depth of the depressions from the characteristic weight value taking into account an intrinsic weight value of the mount substrate without the wetting agent, the density of the wetting agent and a total surface area occupied by the depressions in the area of the surface of the mount substrate.
