Thermal Imaging Of Heat Sources In Thermal Processing Systems
Thermal imaging of heat sources in thermal processing systems for determination of workpiece temperature are provided. In one example, a thermal processing apparatus can include a processing chamber, a workpiece support, a plurality of heat sources configured to heat a workpiece, and at least one camera. The at least one camera can capture one or more images of thermal radiation of the plurality of heat sources during thermal treatment of the workpiece. In one example, a method for calibrating the camera can include obtaining the one or more images of thermal radiation of at least one heat source, obtaining one or more reference signals indicative of irradiation of the at least one heat source, and calibrating the camera based at least in part on a comparison between the one or more images of thermal radiation and the one or more reference signals indicative of irradiation of the heat source.
Scalable thermoelectric-based infrared detector
Device and method of forming the devices are disclosed. The method includes providing a substrate prepared with transistor and sensor regions. The substrate is processed by forming a lower sensor cavity in the substrate, filling the lower sensor cavity with a sacrificial material, forming a dielectric membrane in the sensor region, forming a transistor in the transistor region and forming a micro-electrical mechanical system (MEMS) component on the dielectric membrane in the sensor region. The method continues by forming a back-end-of-line (BEOL) dielectric having a plurality of interlayer dielectric (ILD) layers with metal and via levels disposed on the substrate for interconnecting the components of the device. The metal lines in the metal levels are configured to define an upper sensor cavity over the lower sensor cavity, and metal lines of a first metal level of the BEOL dielectric are configured to define a geometry of the MEMS component.

Thermal pile sensing structure integrated with capacitor
The present invention discloses a thermal pile sensing structure integrated with one or more capacitors, which includes: a substrate, an infrared sensing unit and a partition structure. The infrared sensing unit includes a first and a second sensing structure. A hot junction is formed between the first and the second sensing structures at a location where the first and the second sensing structures are close to each other. A cold junction is formed between the partition structure and the first sensing structure at a location where these two structures are close to each other. Another cold junction is formed between the partition structure and the second sensing structure at a location where these two structures are close to each other. A temperature difference between the hot junction and the cold junction generates a voltage difference signal. Apart of the partition structure forms at least one capacitor.

Infrared Sensor And Method For Electrical Monitoring
An inexpensive thermopile temperature detector is particularly adapted to monitoring of electrical equipment, such as a power bus bar, within an enclosed area such as a cabinet. The detector may have a plastic housing, a thermopile sensor and a plastic Fresnel lens. Each sensor also includes a calibrated element such that, but for calibration, the same sensor may be used for various applications for different target sizes and distance or, more generally, with respect to effective target percentage of field of view.
