Latest Patents

One of Yeeling L Lee's latest patents is a process for top-surface-metallurgy plate-up bonding and rewiring for multilayer devices. This device repair process involves the removal of a passivation polyimide layer through a two-step ash process. The device is rotated during the second-half ash, followed by cleaning with sodium hydroxide (NaOH) and a light ash step. After the passivation layer is removed, a seed layer is deposited, and a photoresist is formed to create bond sites. Repair metallurgy is then plated through these bond sites by coupling the device to a fixture and applying current for plating. The contact is established through bottom surface metallurgy. Finally, the residual seed layer is removed, and a laser delete process is implemented to disconnect and isolate the nets of the device.
