Method of removing free halogen from a halogenated polymer insulating layer of a semiconductor device and resulting semiconductor device

   
   

A method is disclosed for removal of free halogen from a semiconductor device insulating layer, in particular, a halogen-containing polymer insulating layer. The free halogen is removed by contacting the insulating material with hydrogen ions under conditions which generate gaseous hydrogen halide which is then removed. A semiconductor device containing such treated insulating materials is also disclosed. The invention is particularly useful in removing free fluorine from fluorinated polymer insulating layers.

Un método se divulga para el retiro del halógeno libre de una capa de aislamiento del dispositivo de semiconductor, en detalle, de una capa de aislamiento con halógeno del polímero. El halógeno libre es quitado entrando en contacto con el material aislador con los iones de hidrógeno bajo condiciones que generen el halide gaseoso del hidrógeno que entonces se quita. Un dispositivo de semiconductor que contiene tales los materiales aisladores tratados también se divulga. La invención es particularmente útil en quitar el flúor libre de capas de aislamiento fluoradas del polímero.
