Invasive attacks start with partial or full removal of the chip package in order to expose the silicon die. There are several methods, depending upon the package type and the requirements for further analysis. For microcontrollers, partial decapsulation is normally used, so that the device can be placed in a standard programmer unit and tested. Some devices cannot be decapsulated and still maintain their electrical integrity.
In this case the chip die has to be bonded to a chip carrier using a bonding machine which connects to the bonding pads on the die with thin aluminium or gold wire (Figure 49). Such bonding machines are available from different manufacturers and can be bought second-hand for less than £5,000. The contacts to the die can be also established using microprobing needles on a probing station.
