摘要： A pressure transducer employs a tubular glass structure of a "D" shaped cross section, with the arcuate section of the "D" shaped configuration being substantially thicker than the base section. A sensor array is positioned on the underside of the base section while a pressure conducting fluid is directed through the tubular member to provide deflection of the base to cause the sensor array to provide an output indicative of pressure variations in the fluid medium. The sensor array as positioned on the underside of the base is both electrically and mechanically isolated from the pressure conducting medium.

摘要： A transducer housing consists of a first and a second section. The first section contains an internal hollow into which a transistor header is mounted. The header, as mounted in the first section, is firmly secured within the section by means of a locking ring or other arrangement. Located in the internal hollow of the first section is a printed circuit board which has a plurality of apertures on the surface thereof each of which communicates with an extending tubular post on the opposite surface. Leads from the header are directed through the apertures in the printed circuit board and extend into the tubular posts. The second housing section is emplaced on the first section and contains a series of hollow metal tubular connectors or posts. These are inserted over the metal tubular posts of the header containing the leads and are crimped so that the posts of the transistor header as well as the leads are connected both electrically and mechanically to the tubular posts extending from the second housing section. Based on the above noted configuration, the housing sections serve to hold the transducer as mounted in the header in a firm and fixed position while enabling installation and interconnection of the transistor header in a rapid and simple manner based on the fact that the leads emanating from the header are crimped internally within the housing sections.

摘要： A semiconductor transducer structure is fabricated by utilizing varying height diffused layers in a sacrificial wafer. A carrier wafer has a dielectric layer on a top surface which includes a layer of glass. The sacarificial wafer, after beign subject to diffusion of highly doped semiconductor material, exhibits a plurality of varying depth regions. These regions manifest the basic transducer structure. By utilizing selective etching, one can thus form a transducer structure on the sacrificial wafer which is bonded to the carrier wafer by means of an electrostatic bond. The resultant method and structure enables one to provide transducers with improved operating characteristics which are adaptable for many different modes of operation.

The members are positioned in congruency and a first member which may be a composite member has a diaphragm area located on the surface thereof to which a piezoresistive gage is bonded. The gage is surrounded by an aperture in another member to enable leads from the gage to be directed to an interconnection and circuit board also fabricated from an insulator material. The structure provides isolation to the patient in regard to the biasing source used for the gage array and also provides isolation based on external voltage which serves to protect the transducer during operation.

摘要： A method of fabricating a high pressure piezoresistive pressure transducer having a substantially linear pressure versus stress output over its full range of operation. The method involves bonding a carrier wafer having a dielectric isolating layer on one surface and a supporting member on the opposite surface, to a pattern wafer containing at least two single crystalline longitudinal piezoresistive sensing elements of a second conductivity. Both the pattern wafer and sections of the carrier wafer are etched leaving the piezoresistive sensing elements bonded directly to the dielectric isolating layer, and a diaphragm member having a deflecting portion and a non-deflecting portion. The diaphragm member is constructed to have an aspect ratio which is of the order of magnitude of one. The piezoresistive sensing elements have a large transverse piezoresistive coefficient normal to the plane of the diaphragm and both a large longitudinal piezoresistive coefficient and a small transverse piezoresistive coefficient in the plane of the diaphragm. One of the at least two piezoresistive sensing elements is positioned above the non-deflection portion of the diaphragm in an area of minimal longitudinal stress and the other is positioned above the deflecting portion of the diaphragm in an area of high compressive stress. The positioning of the second sensor over the deflecting portion of the diaphragm is selected so that there will be equal and opposite resistance changes registered from the sensors. The method results in an improved transducer design when compared to prior art devices.

摘要： A glass header structure for a pressure transducer employs a cylindrical member fabricated from a borosilicate glass having a thermal expansion coefficient which matches silicon. The glass header has a central aperture which extends from the top to the bottom surface. Positioned about the central aperture are four smaller apertures located at 90 degree intervals and each containing an elongated terminal pin. The pins are of a nail head configuration with a flat top head of a larger diameter than the diameter of the apertures and of the main pin body. Affixed to the flat top surfaces of the terminal pins by means of ball bonding are wires which connect to the terminal areas of a semiconductor pressure transducer which is mounted over the central aperture of the header. In this manner, the glass header serves to electrically and mechanically isolate the semiconductor transducer from the external environment and to further provide isolation of the transducer from voltage and heating effects which are produced during the assembly process necessary to fabricate a complete transducer unit.
