Multiple seal-ring structure for the design, fabrication, and packaging of integrated circuits

A method of fabricating an electronic device for flexible packaging, comprising:

• providing a wafer having an outer seal-ring about a plurality of integrated circuit blocks disposed on the wafer and at least one inner seal-ring about each of at least two subsets of the plurality of integrated circuit blocks, wherein each integrated circuit block is designed to be used either individually or in parallel with one or more other integrated circuit block;
• determining whether to package the entire wafer as one unit or to perform die cutting of the wafer to package separate sub-units of the wafer, wherein each subunit has a subset of the plurality of integrated circuit blocks;
• fabricating signal interconnects between groups of integrated circuit blocks that operate in parallel after packaging;
• if no die cutting is performed, packaging the wafer with all of the plurality of integrated circuit blocks packaged to operate in parallel as a single processing unit with the outer seal-ring encompassing and protecting the plurality of integrated circuit blocks;
• and
• if die cutting is performed, performing die cutting of the wafer into at least two die in which each die has at least one inner seal-ring encompassing and protecting each integrated circuit block of the die, and packaging each cut die, wherein any die having two or more integrated circuit blocks is packaged to operate the two or more integrated circuit blocks in parallel.
