Title: Laser and electric discharge composite working method and device
Inventor: AOKI NOBUTADA
IPC: B23K26/00
Filed: 1998-01-12
Abstract: PROBLEM TO BE SOLVED: To perform working having high accuracy and a smooth finishing surface, by converging electric discharge energy on laser plasma on the surface of a target to guide the energy to a working point, to work the target by the energy. SOLUTION: A pulse laser having high-peak output is applied to a laser device 18. When a pulse laser beam 23 having some fixed or more pulse energy is radiated to a target surface, a target atom is emitted by ablation concurrently generating laser plasma. A high-density electron existing in the laser plasma acts as a trigger for electric discharge to cause electric discharge between an anode 11 and a target 12 by an electric charge condensed in a capacitor 13. At that time, since electric discharge energy is converged to be concentratedly injected into the laser plasma on the surface of the target 12, the target surface in the portion of a laser plasma generating point can be selectively worked.

Filed: 1997-01-14
Abstract: PROBLEM TO BE SOLVED: To attain especially low contact resistance by forming an electrode metal on an oxide doped layer formed on the surface of an n-type contact layer. SOLUTION: The surface of an n-type GaN contact layer 1 is subjected to oxygen plasma ashing under conditions of an oxygen pressure 0.8Torr, plasma power 200W and an ashing time 2min and then an electrode is formed thereon by forming a Ti layer 2, an Al layer 3, a Pt layer 4 and an Au layer 5 sequentially. An n-contact layer thus formed exhibits ohmic characteristics with high reproducibility (without requiring any annealing) and has contact resistance of 5×10<-5> Ωcm<2> . Since an oxygen doped layer is formed closely to the surface of a contact layer, i.e., an n-type gallium arsenide based semiconductor layer, in the contact electrode and an electrode metal is formed on the oxygen doped layer, the n-type contact layer is heavily doped with oxygen donor in the vicinity of the surface thereof and a low resistance n-type contact layer is obtained.
