Abstract: PURPOSE:To enable to shorten the gate length by a method wherein a high melting point metal is made to contain an element serving as one conductivity type impurity, and a one conductivity type gate region is formed by heat-treating said metal as the gate electrode. CONSTITUTION:An N type semiconductor layer 12 serving as the channel region is formed in a semi-insulation GaAs substrate 10. Its surface is provided with W-Si-Be alloy, which is then etched with a photo resist 13 as a mask, thus forming the gate electrode 14. N<+> injected layers 15 and 16 are formed by Si implantation, and the source region 15' and the drain region 16 made of an N<+> semiconductor layer by heat treatment. At this time, a P type semiconductor layer 17 serving as the gate region is formed by the diffusion of Be, the impurity contained in said electrode 14, by heat treatment. The electrode 14 is shortened more than the photo resist 13, therefore the gate length of said layer 17 can be reduced. Ohmic electrodes made of Au-Ge series are formed to the source region 15' and the drain region 16', which electrodes are made as the source electrode 18 and the drain electrode 19.

Title: Laser beam machine
Inventor: NAGABORI MASAYUKI
IPC: B23K26/064
Filed: 1998-04-01
Abstract: PROBLEM TO BE SOLVED: To enable miniaturization of the mirror and to attain low cost, improved manufacturing efficiency, and enhanced adjustment workability by reflecting a laser beam converged by a condensing lens with a plurality of mirrors and, after adjusting the outgoing direction, emitting from the outgoing port of the machining head to a workpiece. SOLUTION: A laser beam 12 from a laser generator is converged by a condensing lens 11, reflected by mirrors 13, 14, with the outgoing direction adjusted, and emitted from the outgoing port 15 to form a focus 17 on a workpiece 16 for machining like cutting. In this case, the laser beam 12 through the condensing lens 11 is gradually reduced in diameter and reflected by the mirrors 13, 14. For example, the diameter D of the laser beam 12, reflected by the mirror 13 and made incident on the mirror 14, becomes smaller compared with the diameter C of the preconverged laser beam 12, assuming C>D. As a result, the mirrors 13, 14 can be designed to be small in size. Further, the mirrors can be two or more and desirably cooled by water directly, so that they are stabilized for a long period.
