摘要: A pyrometer cell comprises a first ferroelectric capacitor, a second ferroelectric capacitor, and a difference circuit for determining the difference between the polarization charge, voltage, or current between the first and second ferroelectric capacitors. The cell is pulsed a plurality of times and an integrator circuit connected to the difference circuit provides an enhanced output signal representative of the integrated difference. An infrared imager is formed by an array of the pyrometer cells, with one ferroelectric capacitor in each cell exposed to an infrared source and the other ferroelectric capacitor not exposed to the infrared source.

摘要: A ferroelectric/pyroelectric sensor employs a technique for determining a charge output of a ferroelectric scene element of the sensor by measuring the hysteresis loop output of the scene element several times during a particular time frame for the same temperature. An external AC signal is applied to the ferroelectric scene element to cause the hysteresis loop output from the element to switch polarization. Charge integration circuitry, such as a combination output capacitor and operational amplifier, is employed to measure the charge from the scene element. Preferably, the ferroelectric of the scene element is made of an economical and responsive strontium bismuth tantalate, SBT, or derivative thereof, disposed directly between top and bottom electrodes. Because of the frequency characteristics of the sensor, created by the external AC signal, the element need not be thermally isolated from the silicon substrate by a traditional air bridge, which is difficult to manufacture, and instead is preferably thermally isolated by spin-on-glass, SOG. To prevent saturation of an output signal voltage of the sensor by excessive charge accumulation in an output capacitor, the sensor preferably has a reference element configured electrically in parallel with the scene element. When the voltage of the AC signal is negative the output capacitor is discharged by flowing current through the reference element thus interrogating the polarization of the reference element which is compared to and subtracted from the polarization of the scene element for each cycle. The polarization difference measured for each cycle over a set time period are summed by an integrating amplifier to produce a signal output voltage.

摘要: A precursor for forming a thin film of layered superlattice material is applied to an integrated circuit substrate. The precursor coating is heated using rapid thermal processing (RTP) with a ramping rate of 100° C./second at a hold temperature in a range of from 500° C. to 900° C. for a cumulative heating time not exceeding 30 minutes, and preferably less than 5 minutes. In fabricating a ferroelectric memory cell, the coating is heated in oxygen using RTP, then a top electrode layer is formed, and then the substrate including the coating is heated using RTP in oxygen or in nonreactive gas after forming the top electrode layer. The thin film of layered superlattice material preferably comprises strontium bismuth tantalate or strontium bismuth tantalum niobate, and preferably has a thickness in a range of from 25 nm to 120 nm. The process of fabricating a thin film of layered superlattice material typically has a thermal budget value not exceeding 960,000° C.-sec, preferably less than 50,000° C.-sec.
