Failure analysis of ICs needs physical access to packaged chips or components, the first step is to remove its covering plastic packaging material. This procedure is called Integrated Circuit Decapsulation.
MSS Company uses lasers to create grooves, which allows removal of colloid on the surface. Chemical etching is then used to uncover the shape and design of the chip or IC. Combining the advantages of laser openings and conventional chemical etching can significantly increase the accuracy of partial openings and reduce the exposure time of the sample with a chemical etching solution, thereby enhancing the result. This process can be applied to any package and any metal wire (Au, Cu, Al, and Ag).
● Use laser to create grooves
● Different type of IC Decap samples
● Decap with laser, Cu wire & 2nd bonding is without acid damage
● Decap 4 array Cu bonding wires, SEM inspection show the wires are free of damage and epoxy
● Ag wire Decap+SEM
