First Claim
Patent Images
1. A method for enhancing semiconductor chip process variability and lifetime reliability through a three-dimensional integration applied to electronic packaging, said method comprising:
- (a) providing a first semiconductor chip essentially consisting of a microprocessor, a plurality of performance and memory resources, including selectively functional units, control macros, elements of data flow, register files and memory arrays;
(b) providing one or more second semiconductor chips in a superimposed arrangement over said first semiconductor chip, said second semiconductor chip including an on-chip controller and redundant resources actuatable upon recognition of a faulty resource or plurality of faulty resources on said first semiconductor chip;
(c) configuring at least one of the redundant resources on said second semiconductor chip as a performance enhancer for at least one of the resources on said first semiconductor chip; and
(d) incorporating redundancies on said second semiconductor chip thereon for critical macros on said first semiconductor chip selectively comprising vectors, fixed or floating point execution blocks, auxiliary pipelines and diverse component units.
