By H. Adam

1965 Transactions of the 3rd overseas Vacuum Congress, quantity 2 offers the equipment for the epitaxial development of silicon, which uses an ultra-thin layer of a silicon alloy at the substrate floor to increase epitaxial layers at temperature as little as 750°C. This booklet discusses the aptitude merits of the method and the mechanism of the epitaxial progress procedure.
Organized into 4 periods encompassing forty two chapters, this quantity starts off with an outline of the precise effect of the skinny alloy layer. this article then describes the radical X-ray procedure and its software to semiconductor thin-film difficulties. different chapters examine the sector of digital service shipping in semiconductor movies with specific connection with lively thin-film units and their general habit. the ultimate bankruptcy offers with the beta-ray single-scatter gauge, that are established and defined in extremely simple operation.
This ebook is a important source for physicists and scientists.

A I'extremite opposee de la gamme de sensibilite, on a utilise des appareils particulierement sensibles pour des etudes dfadsorption de gaz. Mais, dans le domaine intermediate qu'il faut utiliser pour le controle en fonctionnement continu de depots pouvant etre constitues d'une fraction de couche monoatomique a plusieurs couches atomiques (par exemple le germanium) on se heurte a des difficultes dues au choc thermique que regoit le crista!. Les gradients thermiques provenant de lfabsorption de I'energie rayon nee par la source d'evaporation peuvent entralner des variations de frequence plus importantes que celles qu'entralne la masse du depot etudie.

H) Microseeding. The ideal materials preparation for active thin film devices would include a clear definition of the crystalline orientation of the layer. This can only be achieved by a seeding method which predefines the orientation by the use of a perfect seed. It is an additional step to the methods outlined to induce monocrystal growth in the travelling solvent or temperature gradient growth by adding a seed crystal or forming an oriented seed. It seems likely that first results can be achieved by a seeding method in which a small monocrystal of proper orientation is included in a substrate cavity which is situated at the origin of the travelling solvent growth.

B. im Falle von Germanium) fortlaufendzu verfolgen, gibt es infolge des thermischen Schocks des Kristalls gewisse Schwierigkeiten. Thermische Gradienten, die durch die Absorption von Strahlung seitens der Verdampfungsquelle hervorgerufen werden, konnen zu Frequenzanderungen fiihren, die grosser sind als die, die sich aus dem Auftrag der Masse, die untersucht werden soil, ergeben.
