As methane concentration was varied, the textures of diamond films deposited on Si(100)substrate were observed by XRD,SEM and Raman spectroscope. As a result, $O_{2}$ plasma etching has been useful to observe microscopic structure of diamond films by SEM. The cross section of diamond films deposited on Si(100)substrate with 4% concentration of methane to hydrogen was a polycrystal like a pillar. The diamond crystal like a pillar has been oriented to (110)surface and the high quality diamond film with FWHM of Raman spectra being 3.8 $cm^{-1}$ / has been grown. As time goes by deposition time, the preferred orientation increases
