Abstract
The invention relates to a method for fabricating chip elements provided with a groove from devices formed on a wafer. The method comprises the steps consisting in, depositing a sacrificial film on the wafer so as to leave a central part of each device exposed and to cover an edge of the device at the level of which the groove is to be formed; applying a mold on the sacrificial film; injecting a hardenable material into the mold; hardening the hardenable material; dicing the wafer between the devices; and eliminating the sacrificial film.
