Title: Light energisable thyristor emitter structure - has both surface zones without contacts in region of light impingement
Inventor: SILBER DIETER DIPL PHYS DR
IPC: H01L31/111
Filed: 1973-12-03
Abstract: The thyristor is ignitable by light impingement and has at least four zones of alternating conductivity with contacts on the two outer zones. In the latter is formed a surface region through which the light penetrates into the thyristor, and this region is not contacted and is thinner than the other part of the respective zone. This region without contacts has as high emitter effect as possible. The transversal resistance of this zone may be so high as to attain an increase of the permissible current rise rate. Preferably the thickness of the outer zone in the non-contacted region is less than 4 microns. The emitter region is produced by diffusing the entire zone with subsequent thickness reduction of the non-contacted region. This is followed by a final diffusion.
