Title
(EN) A METHOD AND ARRANGEMENT FOR TREATING SILICON PLATES
(FR) PROCEDE ET AGENCEMENT DE TRAITEMENT DE PLAQUES DE SILICIUM
Abstract
(EN)
A method for treating a silicon plate, a so-called wafer, in a cold-wall reactor when using the so-called CVD-technique in order, among other things, to deposit substances on the silicon plate by introducing different gases into the reactor. The invention is characterized in that the reactor (1) is configured as a microwave cavity, and in that one treatment stage comprises introducing microwave energy into the reactor from a microwave generator (5), thereby to heat the silicon plate (2) to a desired temperature, which is read-off in a known manner. According to one preferred embodiment, a suitable etching gas is introduced into the cold-wall reactor and microwave energy is then introduced into the reactor (1) at a power level such as to form a plasma in the reactor, thereby to back-etch a substrate or to clean the reactor from possible impurities therein.
(FR)
L'invention concerne un procédé de traitement d'une plaque de silicium, appelée tranche, dans un réacteur à parois froides, lorsque l'on utilise ladite technique CVD (de déposition en phase gazeuse par procédé chimique), afin, entre autre chose, de déposer des substances sur la plaque de silicium par introduction de différents gaz dans le réacteur. L'invention est caractérisée en ce que le réacteur (1) est configuré comme une cavité à micro-ondes et en ce qu'une étape de traitement consiste à introduire dans ledit réacteur une énergie à micro-ondes provenant d'un générateur de micro-ondes (5), afin de chauffer ainsi ladite plaque de silicium (2) à une température désirée, laquelle est affichée de manière connue. Selon un mode de réalisation préféré, on introduit un gaz de gravure adapté dans le réacteur à paroi froide, puis on introduit une énergie à micro-ondes dans ledit réacteur (1) à un niveau de puissance permettant de former un plasma dans ce dernier, de manière à graver en retrait un substrat ou à nettoyer le réacteur des impuretés qu'il peut éventuellement contenir.
