A semiconductor sensor adapted to detect with a high degree of sensitivity small magnitudes of a mechanical force, presence of traces of a gas or light. The sensor includes a high energy gap (i.e.,.about.1.0 electron volts) semiconductor wafer. Mechanical force is measured by employing a non-centrosymmetric material for the semiconductor. Distortion of the semiconductor by the force creates a contact potential difference (cpd) at the semiconductor surface, and this cpd is determined to give a me...

A semiconductor device in which a top-contact semiconductor body is thermo-electrostatically face down bonded to a vitreous support carrying patterned metallization forming leads registered with the top contacts, and a protective insulative coating is provided over at least portions of the leads to preclude shortcircuiting to exposed portions of the semiconductor body.

A semiconductor device comprising a semiconductor body portion having a shallow surface layer which is higher doped than the bulk of the semiconductor body portion, and a metal electrode on this layer and forming a Schottky barrier with the body portion. The layer serves to control the effective height of the barrier. The depth of the layer is such that the layer is substantially depleted of charge carriers in the zero bias condition whereby the slope of the reverse current-voltage characteristi...

In a semiconductor device, the surface of a semiconductor element is covered with a silicone varnish in which the side chain radical ratio between methyl radicals and phenyl radicals is 20:1 or greater, whereby the element is effectively shielded from the external moisture.

A semiconductor device, particularly an integrated semiconductor circuit, in which in a region (island) of a given conductivity type a group of semiconductor circuit elements is provided having a common zone. According to the invention, the region comprises a highly doped zone of the same conductivity type, which within the semiconductor body substantially entirely surrounds the group of circuit elements and is not contacted or is contacted only locally. Due to the presence of said highly doped ...
