摘要： High-resolution thermopile infrared sensor array having a plurality of parallel signal processing channels for the signals of a sensor array and a digital port for serially emitting the signals. Each signal processing channel comprises at least one analog to digital converter and is assigned a memory for storing the results of the analog to digital converters. Power consumption of the infrared sensor array is reduced in the case of a sensor array with at least 16 rows and at least 16 columns, in that no more than 8 or 16 pixels are connected to a signal processing channel. The number of signal processing channels corresponds to at least 4 times the number of rows. Some of the signal processing channels are disposed in the intermediate space between the pixels and others are disposed in an outer edge region of the sensor chip surrounding the sensor array along with other electronics.

摘要： A thermopile infrared individual sensor includes a housing filled with a gaseous medium. It has optics and one or more sensor chips with individual sensor cells with infrared sensor structures with reticulated membranes, infrared-sensitive regions of which are each spanned by at least one beam over a cavity in a carrier body. The thermopile infrared sensor uses monolithic Si-micromechanics technology for contactless temperature measurements. In the case of a sufficiently large receiver surface, this outputs a high signal with a high response speed. A plurality of individual adjacent sensor cells are combined with respectively one infrared-sensitive region with thermopile structures on the membrane on a common carrier body of an individual chip to a single thermopile sensor structure with a signal output in the housing, consisting of a cap sealed with a base plate with a common gaseous medium.

摘要： An SMD-enabled infrared thermopile sensor has at least one miniaturized thermopile pixel on a monolithically integrated sensor chip accommodated in a hermetically sealed housing which consists of an at least partially non-metallic housing substrate and a housing cover. A gas or a gas mixture is contained in the housing. The sensor has a particularly low overall height, in particular in the z direction. This is achieved by virtue of an aperture opening being introduced in the housing cover opposite the thermopile pixel(s), which aperture opening is closed with a focusing lens which focuses the radiation from objects onto the thermopile pixel(s) on the housing substrate, and by virtue of a signal processing unit being integrated on the same sensor chip next to the thermopile pixels, wherein the total housing height and the housing cover are at most 3 mm or less than 2.5 mm.

The object of the invention consists of specifying a thermopile infrared sensor using monolithic Si-micromechanics technology for contactless temperature measurements, which, in the case of a sufficiently large receiver surface, outputs a high signal with a high response speed and which can operated in a gaseous medium with normal pressure or reduced pressure and which is producible in mass produced numbers without complicated technology for sealing the housing. This is achieved by virtue of, in each case, combining a plurality of individual adjacent sensor cells (18) with respectively one infrared-sensitive region with thermopile structures (14, 15) on the membrane (12) on a common carrier body (1) of an individual chip to a single thermopile sensor structure with a signal output in the housing, consisting of a cap (12) sealed with a base plate (3) with a common gaseous medium (10).

摘要： Thermopile infrared sensor structure with a high filling level in a housing filled with a medium (15), consisting of a carrier substrate (11) which has electrical connections (28, 28′) to the outside and is closed with an optical assembly (13), wherein a sensor chip (14) is applied to the carrier substrate (11) in the housing, which chip has a plurality of thermoelectric sensor element structures (16), the so-called “hot contacts” (10) of which are located on individual diaphragms (3) which are stretched across a respective cavity (9) in a silicon carrying body (24) with good thermal conductivity, wherein the “cold contacts” (25) are located on or in the vicinity of the silicon carrying body (24). The problem addressed by the invention is that of specifying a thermopile infrared array sensor (sensor cell) which, with a small chip size, has a high thermal resolution and a particularly high filling level. This sensor is preferably intended to be operated in gas with a normal pressure or a reduced pressure and is intended to be able to be mass-produced in a cost-effective manner under ultra-high vacuum without complicated technologies for closing the housing. This is achieved by virtue of the fact that a radiation collector structure (17) is located above each individual diaphragm (3) of the sensor element structures (16) which spans a cavity (9).
