Latest Patents
One of Kadowaki's latest patents is an apparatus for manufacturing bonded substrates. This invention addresses the common issue of defects in bonded substrates. The apparatus operates by attracting substrates through vacuum when the pressure in a vacuum chamber is at atmospheric level. As the vacuum chamber is depressurized, each chuck unit electrostatically attracts the associated substrate. The pressure for attracting each substrate is controlled to match the pressure in the vacuum chamber, preventing any movement or falling of the substrates. This ensures that the first and second substrates are bonded together with precise alignment.
