Because of their good focusabilily and strong interaction with most substrates, UV laser tools can play an important role in the fabrication of miniature structures.
Of all materials, diamond is harder than any known solid, while also exhibiting the highest values for elastic modulus, atomic density, Debye temperature and thermal conductivity at room temperature. Diamond is chemically inert, and is highly transparent throughout a broad range of the optical spectrum. It is a wide bandgap semiconductor that may be useful at high temperatures or high voltages.
Laser Direct-Write Technology and Its Low Processing Temperature Low Cost Applications, by David Lui
Laser direct-write is a new processing technology that allows the rapid fabrication of micro devices and circuits. These micro devices and circuits find applications in a variety of areas such as microelectronics, photonics, MEMS, and MOEMS.
Many components used in modern products are getting smaller. Over the last three decades, features in integrated-circuit technology have been reduced in size by approximately two orders of magnitude, and micromotors as small as a human hair have been fabricated using photolithography.
