A heating station for use with, for example, a high speed parallel manufacturing line for manufacturing insulated glass units, the heating station including at least two opposing infrared heaters that linearly heat spacer material that includes integrated temperature sensitive adhesive. Each of multiple linear infrared heaters includes a respective associated temperature sensor. The infrared heater and temperature sensor are coupled to a spacer heating controller that controls intensity and/or duration of heating of the spacer material and adhesive to provide optimal wetting and adhesive qualities. Individual control of the at least two opposing linear infrared heaters compensates for variable environmental conditions affecting spacer material at different locations around and insulated glass unit.

The invention relates to a method for fabricating a detection device, comprising the following steps: producing thermal detectors and an encapsulating structure by way of mineral sacrificial layers; partially removing the mineral sacrificial layers, by wet chemical etching in an acid medium, so as to free the thermal detectors and to obtain a peripheral wall, and to free an upper portion of the encapsulating thin layer; the peripheral wall then having a lateral recess resulting in a vertical enlargement of the cavity, between the readout substrate and the upper portion, this lateral recess defining an intermediate area; producing reinforcing pillars, arranged in the intermediate area around the matrix-array of thermal detectors.
