Abstract

L'invention concerne les circuits intégrés. Les thyristors PNPN isolés de l'invention comprennent quatre régions verticales successives formées dans une région située entièrement au-dessus d'un caisson enterré 408 dans un substrat 410. Les différents thyristors sont isolés les uns des autres par des diffusions profondes d'une impureté correspondant à celle du substrat. Les signaux de gâchette du thyristor peuvent provenir d'un transistor PNP latéral possédant deux régions communes avec le thyristor. Application aux mémoires à semi-conducteur.
