Extended Data Fig. 1: Preparation of the electronic module and probes.

a, Apply laser ablation to form the geometrical layouts and circuit footprints for electronic modules and probes. b, Use ultrasonic flux bath to clean the surfaces of modules and probes after laser ablation. c–e, Fill in laser-ablated via holes with liquid silver paint using a 30 gauge blunt needle to make electrical connections between top and bottom circuits: active HM device (c), BM module (d), passive HM device (e) and probes for BM devices (f). g–j, Solder electronic components on circuit footprint: active HM device (g), BM module (h), passive HM device (i), probes for BM devices (j). k–m, Device operation: passive HM device (k), active HM device (l), BM module (m).
