Title: Oxygen sensor of the resistive- type and method of making the same
IPC: G01N27/12
Filed: 1978-07-20
Abstract: The invention relates to a resistance-type sensor 1 for sensing the partial pressure of oxygen in a combustion gas mixture, and a method of its manufacture. The sensor has a sensing element 3 of a resistance ceramic material, such as titanium dioxide, the surface of the element for exposure to the combustion gases having thereon a nonconductive layer 9 of a catalyst such as platinum or palladium, which catalyst has a higher catalytic activity than the material of the sensor element 3 for oxidation of carbon monoxide and hydrocarbons in the combustion gas to provide for lower temperature activation of the sensor than normally is achieved. The sensor element 3 is supported by a ceramic insulator 5 with conductive leads 11 leading from the sensor to terminals 13 for recording resistance changes. A ceramic housing 17 surrounds the ceramic insulator 5 and a metallic housing 19 contains the ceramic housing 17 for placement of the sensor in a conduit for combustion gases to measure the oxygen partial pressure within such gases. <IMAGE>
Patent GB-2002584-A (GB)
Title: A process for the production of one-transistor storage cells
IPC: H01L21/8242
Filed: 1978-08-08
Abstract: In the production of MOS one- transistor storage cells, it is desirable, to minimise the area of each cell, while ensuring that it has adequate storage capacitance. This is achieved by the invention, in which in a flat surface of a silicon crystal (1) of one conductivity type, a buried layer (2) of the opposite conductivity type is produced by localised redoping and covered with an epitaxial layer (3) of the one conductivity type. In layer (3), the source and drain zones of the MOS field-effect transistor forming the storage cell are then produced by localised re- doping. One zone is produced in two stages (4 and 6), so that this zone alone contacts the buried layer (2) to form a composite source zone (2, 4, 6) of which the buried zone portion (2) extends laterally beneath drain zone (5). As this portion (2) extends over the area of the entire cell and represents its storage capacitance, adequate capacitance is ensured within a small area. The cell is completed conventionally by covering layer (3) with silica and producing a gate electrode and source and drain terminals. <IMAGE>
