Title: Device isolation process for gallium arsenide integrated circuit
Inventor: WANG YUNG-HE
IPC: H01L21/76
Filed: 2000-07-28
Granted: 2001-11-21
Abstract: The present invention relates to a kind of planar device isolation process for gallium arsenide integrated circuit. The manufacture of isolation oxide for the present process uses a kind of low-temperature liquid-phase III-V semiconductor insulation layer technique. This system is operated near room temperature (room temperature to 70 DEG C). By using low temperature characteristics of this technique wherein no destruction for the metal or the photoresist film is generated, metal or photoresist film is used as the stable mask to conduct selective oxidation such that the steps of isolation process and equipment can be greatly simplified. In particular, planar device isolation can be accomplished through the characteristics that the grown oxide layer automatically has the same height as that of the original plane under the mask. In addition, by tuning the opening window width of the isolation region and the related parameters of oxidation process, different isolation depths and widths can be obtained so as to raise the flexibility of process integration.

Granted: 2002-12-11
Abstract: By providing a nitrogen-doped low carrier concentration layer 13 having both of a donor concentration and an acceptor concentration controlled below 1x10<SP>16</SP>/cm<SP>3</SP> at a p-n junction portion between an n-type GaP layer 12 and a p-type GaP layer 14, the luminance can be improved by as much as 20% to 30% over the conventional one. Suppressing the donor concentration and the acceptor concentration in the low carrier concentration layer 13 below 1x10<SP>16</SP>/cm<SP>3</SP> inevitably gives a carrier concentration, which is expressed as a difference between both concentrations, lower than 1x10<SP>16</SP>/cm<SP>3</SP> accordingly. By suppressing the concentration of the donor which serves as the non-emissive center below 1x10<SP>16</SP>/cm<SP>3</SP> to thereby extend the carrier lifetime, and by concomitantly suppressing the carrier concentration at a level significantly lower than that in the adjacent layers 12 and 14, the emission efficiency upon injection of electrons or holes can be improved.
