Latest Patents

Ertl's latest patents demonstrate a keen understanding of the complexities involved in semiconductor fabrication. His first patent, titled "Apparatus for gripping ceramic substrates," introduces a unique gripper. This gripper features angled faces lined with soft metallic pads embedded with diamonds, which engage vertically with microfeatures in ceramic carriers. This design ensures a secure grip during alignment and bonding to base substrates while allowing for a gentle release upon disengagement. The gripper is typically attached to a micromanipulator, facilitating controlled motion and self-adjustment in response to variations in substrate thickness and angle.

Another noteworthy patent is the "Alignment method for semiconductor optical devices upon carriers." This innovation describes a system for accurately mounting two semiconductor optical devices in close alignment. The devices are placed on separate carriers: one flat and one wedge-shaped. By manipulating the position of the carriers on an inclined plane, the coupling faces of the optical devices can be aligned with precision. The method involves applying a liquid adhesive that allows for sliding action and securing the devices post-alignment through adhesive curing.
