A laser device has a substrate and at least one GaN-based layer upon a first surface of the substrate, and the laser device is cleaved by cutting linear grooves into a second surface of the substrate such that the grooves are in alignment with vertical planes of the substrate. The substrate and the at least one GaN-based layer are cleaved along the vertical planes. The cutting is performed using a laser beam from an external laser source.

A contact pressure sensor () and method for manufacturing a contact pressure sensor for detecting contact pressure between two surfaces is disclosed. The contact pressure sensor disclosed comprises a substrate () for supporting the sensor and a contact pressure sensitive layer () sensitive to pressure applied to the contact pressure sensor. The method disclosed also comprises transferring a process post structure () that is formed on a first process support substrate () from the first process support substrate to a second contact pressure sensor support substrate (
