The threshold voltage thus can be tuned by the thickness of the thin metal layer.

The metal layer is then applied to the base, creating the data layer.

In this geometry each of the metal layers act effectively as electrodes, and current will flow perpendicular through the construction.

It's quite simple: take a metal layer, thick enough that it is just barely opaque.

In cold snow, ice would freeze to the bottom metal layer and made them very difficult to move.

It's actually a metal layer in the factor.

Target material (usually a thin metal layer) is deposited (on the whole surface of the wafer).

If this problem occurs, unwanted parts of the metal layer will remain on the wafer.

The metal layer on the disc is usually made of silver.

Repeat steps 4-6 to get all metal layers.
