A cmos chip, with a damaged silicon-dioxide layer because its been
punched thru by the static. Sometimes they will continue to function
for a short time. More often you have failures that seem to fix
themselves after a full, let the suuplies go to zero volts, powerdown,
which will reset and momemtarily turn off the scr so formed between the
active part of the transistor and the substrait its made on.
Silicon-dioxide is a perfect insulator, but its built so thin it can
break down and allow a single electron to pass thru it if over voltaged,
often at less than 2 volts above the supply rail, or more than 3/4 volt
below the ground rail. The passage of that single electron creates a
flaw in that layer, which is not normally more than 1 or 2 atoms thick
in modern processes. So it is not a question of will it fail, but when.
