I would think it would destroy any stylus. Found a youtube, looks like a publicity stunt.

I think its just a fun thing.
When I left the BU I was working for in 2006 to move to a new role in Asia, the guys in the fab made me a lovely wafer with a message and some pics on it wishing me well.
I guess actually etching the wafer with some music of course would involve a whole lot more process steps - no way that one would get past our production manager (who in my case by the way always regaled me for trying to push through product quals so I could get my guys out there selling and marketing the stuff ASAP). Lots of fond memories . . . I am out of the industry for the time being on a sabbatical and thoroughly enjoying it.

Of course it was. Mask charges for a 10 inch wafer ran us about 100K. Production costs per wafer anywhere between $5K and $15K depending on the process and number of mask steps.
The total costs for a run of 5 10 inch wafers was over $500K on an IBM process. Freescale would process us through TSMC for even more $$$. This was a prototype run, volume production quote was about $10K per wafer. Yes, these were High $$$$ RF CMOS chips, but silicon fab time doesn't come cheap.
