6、氣體(ti)分布(bu)裝置(zhi):氣體(ti)由(you)進(jin)氣口進(jin)入電除霧器(qi),由(you)于截面積突(tu)然擴大,容易(yi)因(yin)渦流而(er)造成整個截面 積上(shang)的氣體(ti)分布(bu)不均,所以就(jiu)需要在下氣室設(she)置(zhi)氣體(ti)分布(bu)裝置(zhi),氣體(ti)分布(bu)板(ban)開孔(kong)率一般為25% ~ 50%。
7、供電(dian)(dian)(dian)(dian)(dian)系統:用于靜電(dian)(dian)(dian)(dian)(dian)沉積的高壓(ya)(ya)(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan),主要有二種。一(yi)(yi)種是(shi)(shi)可(ke)控(kong)(kong)(kong)硅(gui)移相控(kong)(kong)(kong)制高壓(ya)(ya)(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan), 簡稱可(ke)控(kong)(kong)(kong)硅(gui)電(dian)(dian)(dian)(dian)(dian)源(yuan),它(ta)是(shi)(shi)一(yi)(yi)種“電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)源(yuan)”,其主控(kong)(kong)(kong)量是(shi)(shi)“電(dian)(dian)(dian)(dian)(dian)壓(ya)(ya)(ya)”;另_種是(shi)(shi)恒(heng)流(liu)(liu)高壓(ya)(ya)(ya)直(zhi)流(liu)(liu)電(dian)(dian)(dian)(dian)(dian)源(yuan),簡稱恒(heng)流(liu)(liu)源(yuan),它(ta)是(shi)(shi)一(yi)(yi)種“電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)源(yuan)”,其主控(kong)(kong)(kong)量是(shi)(shi)“電(dian)(dian)(dian)(dian)(dian)流(liu)(liu)”。
