Title: Procede de realisation de plaquettes-substrats orientees, a partir de lingots massifs semi-conducteurs du groupe iii-v
Inventor: SCHILLER CLAUDE
IPC: C30B15/00
Filed: 1987-07-09
Abstract: L'invention concerne un procédé de réalisation pour obtenir des plaquettes-substrats préparées pour recevoir des dispositifs semi-conducteurs intégrés en matériaux du groupe III-V obtenu par tirage Czochralski. Ces matériaux présentant des propriétés anisotropes dont dépendent les performances des dispositifs semi-conducteurs, il est de la plus haute importance de différencier les axes cristallographiques de chaque plaquette avec une précision meilleure que le demi-degré. Selon l'invention cette différenciation est faite en deux étapes. La première étape consiste en la différenciation des axes dès la formation du germe de tirage. A cet effet le germe de tirage est un parallélépipède rectangle dont une arête présente une facette servant d'encoche de fixation du germe durant le tirage. Cette facette est repérée par rapport aux axes caractéristiques du lingot obtenu par tirage et permet de conserver cette information jusqu'à la concrétisation de ladite information par la taille de deux méplats sur le lingot massif lui-même. Le germe de tirage ainsi repéré étant utilisé un grand nombre de fois, la méthode selon l'invention permet un gain de temps considérable lors de l'élaboration industrielle des substrats. Application : élaboration des substrats en arséniure de gallium et phosphure d'indium.
