Toasted chips. (Letters).
The discovery that silicon would explode ("Detonating silicon
wafers can ID elements," SN: 1/19/02, p. 36) is not news to me. I
made a serendipitous discovery over 20 years ago as a computer hobbyist.
I discovered that silicon would explode when I accidentally injected 15,000 volts into some integrated circuits designed for 5 volts.
Fortunately, the detonations were small and no damage was done to
anything except the circuit board. It was toast.
