摘要：
An integrated circuit having structure for isolating circuit sections having at least one differing characteristic. The structure includes a chip guard ring for each circuit section having the at least one differing characteristic. Providing multiple chip guard rings allows for isolation of circuit sections and prevention of ionic contamination, but without increased expense and size. In addition, it is practicable with any IC. The invention also may include an interconnect for electrical connectivity about a chip guard ring.
