本文叙述了电子回旋共振微波等离子体化学气相沉积(ECRPCVD)的工作原理、特点及其应用.ECRPCV D由放电室、淀积室、微波系统、磁场线圈、气路与真空系统组成.处于放电室的等离子体在磁场中做回旋运动,使电子的回旋运动频率与微波频率相同;处于回旋共振条件下的电子有效地吸收微波功率而获得高的能量,从而产生高活性和高密度的等离子体.电离度大于10%,电子密度为1013cm3.ECRPCVD可在低的气体流量、衬底不加热的情况下高速淀积高质量薄膜.以该技术淀积的Si,N4,SiO2薄膜可分别与高温CVD的Si3N4高温热氧化的SiO2相比拟.ECRPCVD淀积a-Si:H淀积速率为通常CVD的20倍,而性能与射频CVD淀积的a-Si:H相当.ECRPCVD 已成功用于淀积多种薄膜。 相似文献

采用微波等离子体化学气相沉积法,用高纯氮气(99.999%)和甲烷(99.9%)作反应气体,在单晶Si(100)基片上沉积C3N4薄膜,利用扫描电子显微镜观察薄膜形貌,表明薄膜由密排的六棱晶棒组成,X射线衍射和透射电子显微镜结构分析说明该薄膜主要由β-C3N4和α-C3N4组成,并且这些结果与a-C3N4相符合较好,由虎克定律近似关系式计算了α-和β-C3N4的傅里叶变换红外光谱和Raman光谱,实验结果支持C-N共价键的存在。 相似文献

CRYSTALLINE CARBON NITRIDE THIN FILMS DEPOSITED BY MICROWAVE PLASMA CHEMICAL VAPOR DEPOSITION 下载免费PDF全文
The crystalline carbon nitride thin films have been prepared on Si (100) substrates using microwave plasma chemical vapor deposition technique. The experimental X-ray diffraction pattern of the films prepared contain all the strong peaks of α-C3N4 and β-C3N4, but most of the peaks are overlapped.The films are composed of α-C3N4 and β-C3N4. The N/C atomic ratio is close to the stoichiometric value 1.33. X-ray photoelectron spectroscopic analysis indicated that the binding energies of C 1s and N 1s are 286.43eV and 399.08 eV respectively. The shifts are attributed to the polarization of C-N bond. Both observed Raman and Fourier transform infrared spectra were compared with the theoretical calculations. The results support the existence of C-N covalent bond in α- and β-C3N4 mixture. 相似文献

STUDIES ON INFRARED AND PHOTOLUMINESCENCE PROPERTIES OF CdIn2O4 FILMS DEPOSITED BY RF REACTIVE SPUTTERING 下载免费PDF全文
Transparent and conductive CdIn2O4(CIO) thin films were prepared successfully by rf reactive sputtering from a Cd-In alloy target in an Ar+O2 atmosphere. The measurement of transmission and reflection spectra, at wavelengths between 0.2 and 6.0μm, and photoluminescence spectrum of the films are reported. The optical properties of the films are analyzed and discussed in detail. Two reasonable methods for calculating the effective mass of the free carrier in the films are presented. 相似文献

The micro-Raman spectroscopy and infrared (IR) spectroscopy have been performed for the study of the microstructure of amorphous hydrogenated oxidized silicon (a-SiOx:H) films prepared by Plasma Enhanced Chemical Vapor Deposition technique. It is found that a-SiOx:H consists of two phases: an amorphous silicon-rich phase and an oxygen-rich phase mainly comprised of HSi-SiO2 and HSi-O3. The Raman scattering results exhibit that the frequency of TO-like mode of amorphous silicon red-shifts with decreasing size of silicon-rich region. This is related to the quantum confinement effects, similar to the nanocrystalline silicon. 相似文献
