METHOD AND APPARATUS FOR FORMING I/O CLUSTERS IN INTEGRATED CIRCUITS

摘要

Disclosed is an I/O cluster (500) and a manufacturing method thereof. The I/O cluster (500) comprises at least two I/O pads (502) positioned adjacent to each other on a die. Each pad (502) includes a first type transistor (516) and a second type transistor (518). The first type transistors (516) of the at least two I/O pads (502) are aligned with each other, and the second type transistors (518) of the at least two I/O pads (502) are aligned with each other. The second type transistors (518) are spaced apart from the first type transistors (516).
