A wafer (W) comprises i) at least one independent die (D1, D2) having internal integrated components (IC), a multiplicity of internal pads (IP1-IP3) connected to some of the internal integrated components (IC), ii) scribe lanes (SL) defined between and around each independent die (Di), and in part of which are defined, for each die (D1, D2), at least a first group (G11, G12) of external pads (EP1-EP3) and/or a second group of external test integrated components (EC). The external pads (EP1-EP3) of each first group (G11, G12) are connected, through conductive tracks, to a chosen one of the internal pads (IP1-IP3) and/or internal integrated components (IC) of the associated die (D1, D2), and arranged to be fed with chosen test signals or to collect test result signals. Each external test integrated components of each second group is connected, through conductive tracks, to a chosen one of the die internal pads and/or die internal integrated components (IC) and/or to external pads of a first group. |
