    A micro IC probe, which is a small, elastic electrical contact, has been developed to improve LSI testing and reduce its cost. No larger than 300×80 μm, it is fabricated with a pitch of 100 μm by micromachining techniques. Its contact resistance is less than 0.5 Ω, satisfying the requirements for conventional probes, and its deflection is 2 to 8 μm to accommodate height differences among LSI pads while maintaining contact.
