Abstract

The invention relates to a method for making a hybrid component (20) comprising the following steps: fixing a detection circuit (21) onto a reading circuit (22); and applying an adhesive (24) between the detection circuit (21) and the reading circuit (22); depositing a sacrificial layer on the detection circuit (21) before the step of fixing the detection circuit (21) onto the reading circuit (22), such that the sacrificial layer extends at least over the edges (27) of the detection circuit (21); and removing the sacrificial layer after the step of applying the adhesive (24) between the detection circuit (21) and the reading circuit (22) so as to form trenches (25) around said detection circuit (21). For short: Figure 6.
