Patent ID: 7635919

Claim:
A microelectronic device, comprising: a semiconductor chip having a first elastic modulus and a first coefficient of thermal expansion; a passivation layer, said passivation layer being applied to an outer surface of said semiconductor chip; an adhesion promoter layer, said adhesion promoter layer being applied to an outer surface of the passivation layer; a first protective substance, said first protective substance being applied to an outer surface of said adhesion promoter layer, said first protective substance having a second elastic modulus; a primer applied to an outer surface of said first protective substance; and a second substance applied to an outer surface of said primer, said second substance having a third elastic modulus and a second coefficient of thermal expansion, said second substance being a tamper-resistant coating, wherein said second elastic modulus is substantially lower than said first elastic modulus and said third elastic modulus and said first coefficient of thermal expansion and said second coefficient of thermal expansion are not substantially similar.
