T1 - Full-field IR-thermography for bond-quality inspection of electroplated aluminium interconnects for Cryo-SiP architectures T2 - 2024 IEEE 10th Electronics System-Integration Technology Conference (ESTC) N2 - This paper addresses thermal transient IR thermography as full-field and non-destructive failure analytical technique to determine the bond quality of microelectronic joints, exploiting the transparency of a silicon chip for MIR photons. The method is exemplified for C2C bonded electroplated Aluminium joints as they could come in as a novel joining technology for 3D heterogeneously integrated Cryo-SiP architectures for ion-trap based quantum computers. We have evaluated the method experimentally for different thermosonic bond parameters and validated it by metallographic sectioning. First results are shown. We could derive that the phase and amplitude image could be used to detect defects in the joints with good sensitivity and within reasonable testing times. This method could have potential to determine zero-hour quality of such joints during inline testing.

We present a systematic study of sintered silver in order to investigate the influence of sintering conditions on thermal and electrical properties. Several sintered silver samples have been prepared under sintering temperature variation between 200°C and 270°C and sintering pressure variation between 5 MPa and 25 MPa. The characterization results diversify up to 200% for thermal conductivity and up to 330% for electrical conductivity. The Wiedemann-France law describes the relationship between electrical and thermal conductivities for bulk metals. We proved that this law applies not only for bulk metal but also for porous sintered metal.
