ABSTRACT:
Disclosed is a method of forming tamper-proof coatings on electronic devices. The method comprises applying a coating of a silica precursor resin and an inorganic salt onto the electronic device, wherein the inorganic salt is one which reacts with a wet etch to yield an acid or base that damages the electronic device. The coated electronic device is then heated at a temperature sufficient to convert the silica precursor resin to a silica containing ceramic matrix.
