ABSTRACT:
A semiconductor pressure transducer includes a monocrystalline semiconductor diaphragm, the outer edges of which are fixed. When subjected to pressure, the transducer produces radial strains of opposite polarity in a central portion thereof and a portion surrounding the central portion close to the edge of the strain inducing region. The diaphragm contains a plurality of elongated resistances formed of semiconductor material of the same conductivity type which are electrically isolated from the diaphragm, per se. Resistances of an individual set which lie in proximity to one another are combined in the form of a bridge. The longitudinal direction of resistances forming one set of opposing arms of the bridge extend along axes of the same crystal system as the longitudinal direction of the elongated resistances forming the other set of opposing arms of the bridge. However, the longitudinal directions of the separate sets of resistances forming the opposing arms of the bridge lie in directions so that they do not orthogonally intersect each other.
