Introduction The more intensive development of science and industry requires the application of new materials with specific properties.
The basis for most of these materials is rare metals and their alloys.
Due to their good mechanical, electrical, electro-erosive, tribological and magnetic properties, tungsten and its alloys are frequently used materials in industry [1].

Introduction Hydrogenated microcrystalline silicon(μc-Si:H) is a kind of complicate multiphase material,which is composed of amorphous silicon phase and micro crystal phase. μc-Si:H has excellent photoelectrical properties and stability, so be wildly used in photovoltaic field[1-3].
RF-PECVD is a key method for the preparation of high quality thin film materials in industry, and is also main method for preparation of μc-Si:H thin film.
At present, a lot of research has focused on effect of the parameters,such as RF power, substrate temperature, deposition pressure, silane concentration etc. on the quality of microcrystalline silicon thin films[4-6].But the thickness of thin films also has important effect on the structure and properties of thin film materials.This paper mainly studied the effect of the thickness on the structure and photoelectrical properties of μc-Si:H thin films.
