  Low-Gain Avalanche Detectors are gathering interest in the High-Energy
Physics community thanks to their fast-timing and radiation-hardness
properties, which are planned to be exploited, for example, in timing detectors
for the upgrades of the ATLAS and CMS detectors at the High Luminosity LHC.
This new technology has also raised interest for its possible application for
photon detection in medical physics, imaging and photon science. The main
characteristic of this type of device is a thin and highly-doped layer that
provides internal and moderate gain, in the order of 10-20, that enhances the
signal amplitude. Furthermore, the thin substrate of a few tens of microns
allows fast carrier collection. This paper details on the fabrication
technology, specifically developed at Brookhaven National Laboratory for the
detection of minimum ionizing particles. The static electrical characterization
and the gain measurements on prototypes will be reported, too.
