221 224 231 234 is essentially a variable resistor in one of four legs of a wheatstone bridge circuit with each of the respective resistances varying in proportion to an applied force or pressure to the transducer 200 the portions of the transducer 200 defined within the dotted lines 225 235 are generally referred to as the u201c active areas u201d since these areas overlay regions of the diaphragms that deflect upon the application of a force thereto the areas of the transducer 200 that are external to the active areas 225 235 are termed the u201c non active u201d areas the difference in size between the active areas 225 235 determines the difference between the operating spans of the sensors 220 230 as has been set forth the four circuit nodes of the wheatstone bridge consist of electrical contacts 226 229 236 239 and which are located in the non active areas of the transducer interconnecting the contacts 226 229 236 239 with the piezoresistors 221 224 231 234 are electrical interconnections 240 which are also p or p silicon these areas are all preferably formed simultaneously it is noted that the contacts 226 229 236 239 being doped p or p are conductive as are the interconnections 240 to provide electrical contact between the piezoresistors 221 224 231 234 and the respective contacts while the terms u201c electrical contacts u201d and u201c interconnections u201d are used for convenience it is understood that these.
