Latest Patents
Tatsunori Shimizu holds a patent for a probe card that suppresses reflection from a circuit board. This invention includes a light-transparent insulating film formed on an interlayer wiring, which allows for easier identification of an alignment mark on the probe. The probe card consists of a circuit board with an insulating film and an electrode pad, along with a probe attached to the electrode pad. The probe features an alignment mark that can be identified from the opposite side of the circuit board. This alignment mark is strategically positioned outside of the electrode pad on the circuit board. The insulating film is a light-transmissive thin film that covers the interlayer wiring. Additionally, an anti-reflection film with lower light transmittance than the insulating film is formed in specific regions on the insulating film, particularly at the position corresponding to the alignment mark and its surrounding area.
