    • 摘要: 对化学气相沉积(CVD)多晶金刚石膜进行激光平整化的正交试验,使用场发射环境扫描电子显微镜(SEM)进行形貌分析,激光共聚焦扫描显微镜测量线粗糙度R_(a)、面粗糙度S_(a)和切缝锥度,分析激光参数对CVD膜平整化的影响。结果表明:影响切缝锥度的因素依次为脉冲宽度、脉冲频率、进给速度和激光电流,影响线粗糙度Ra的因素依次为进给速度、激光电流、脉冲频率、脉冲宽度。正交试验优化后,当激光电流为64 A、脉冲宽度为400μs、脉冲频率为275 Hz、进给速度为100 mm/min时,可获得最佳的切槽表面形貌。采用该优化参数进行面扫描,测得面粗糙度S_(a)为11.7μm;进一步增加入射角度至75°时,面粗糙度S_(a)降低至1.9μm,实际去除效率达到1.1 mm^(3)/min。

    • 摘要: 目的通过分析CVD金刚石膜与几种常用红外光学窗口材料在砂蚀过程中形貌特征以及红外透过率的变化规律,获得CVD金刚石膜在砂蚀过程中的材料去除机制及抗砂蚀性能的关键因素。方法采用喷射式冲蚀磨损系统,对CVD金刚石膜及其他几种常见红外光学材料进行砂蚀性能测试。通过扫描电子显微镜对材料冲蚀后表面形貌进行观察,电子天平测量红外材料砂蚀率。采用红外光谱仪对砂蚀前后红外光学材料进行测量,评价其冲蚀前后的红外性能变化。结果 CVD金刚石膜抗砂蚀能力远高于Ge、ZnS、MgF_2以及石英玻璃。在设定测试条件下,仅经过6 s冲蚀,除CVD金刚石膜外,其余光学材料的红外透过性能下降40%~60%。而CVD金刚石经受240 min的相同条件冲蚀,其红外透过率仅下降9.5%,显示出极佳的抗砂蚀能力。结论 CVD金刚石膜的冲蚀过程主要是微裂纹形成及扩张连接导致材料流失。其他材料的冲蚀过程既有裂纹扩展,也有反复的切削、犁削,而后者是这些材料被冲蚀的主要原因。

    • 摘要: 采用微波等离子体化学气相沉积法,以CH4-CO2为气源,通过改变CO2的流量,探讨了此气源下金刚石膜的生长情况。利用扫描电子显微镜对制备的金刚石膜表面形貌和断面进行了表征,采用Raman和X射线衍射仪对金刚石膜的质量和晶体结构进行分析。结果表明,CH4流量为50 mL/min时,CO2流量在20~40 mL/min范围内可以沉积出完整的金刚石膜,CO2的流量对金刚石膜的表面形貌影响较大,在CO2/CH4=30∶50条件下,沉积速率可达到3.4μm/h,同时可以制备出高质量的金刚石膜。%Diamond films were deposited by microwave plasma chemistry vapor deposition method using CO2/CH4 gas mixtures without supplying additional hydrogen gas. In order to explore the best growth conditions of diamond film, We have a study about the effects of different CO2 flow on the growth of the diamond films. The surface morphologies and cross-section view were characterized by scanning electron microscopy. The qualities and crystal structure were analyzed by Raman spectroscopy and X-ray diffraction. The results show that the diamond films can be obtained within a certain range of CO2 flow rate,which had great influence on the surface morphology,with the CH4 was 50 mL/min. The high qual-ity and orientation of the diamond film was deposited under the condition of CO2/CH4=30∶50,with the growth rate reach 3.4 μm/h.

    • 摘要: 采用微波等离子体化学气相沉积方法(microwave plasma chemical vapor deposition ,MPCVD)在高沉积气压(34.5 kPa)下制备多晶金刚石,利用发射光谱(optical emission spectroscopy ,OES)在线诊断了CH4/H2/O2等离子体内基团的谱线强度及其空间分布,并利用拉曼(Raman)光谱评价了不同O2体积分数下沉积出的金刚石膜质量,研究了金刚石膜质量的均匀性分布问题。结果表明:随着O2体积分数的增加, C2,C H及 Hα基团的谱线强度均呈下降的趋势,而C2,C H与 Hα谱线强度比值也随之下降,表明增加O2体积分数不仅导致等离子体中碳源基团的绝对浓度下降,而且碳源基团相对于氢原子的相对浓度也降低,使得金刚石的沉积速率下降而沉积质量提高。此外,具有刻蚀作用的O H基团的谱线强度却随着O2体积分数的增加而上升,这也有利于降低金刚石膜中非晶碳的含量。光谱空间诊断发现高沉积气压下等离子体内基团分布不均匀,特别是中心区域C2基团聚集造成该区域内非晶碳含量增加,最终导致金刚石膜质量分布的不均匀。%Polycrystalline diamond growth by microwave plasma chemical vapor deposition (MPCVD) at high‐pressure (34.5 kPa) was investigated .The CH4/H2/O2 plasma was detected online by optical emission spectroscopy (OES) ,and the spatial distribution of radicals in the CH4/H2/O2 plasma was studied .Raman spectroscopy was employed to analyze the properties of the diamond films deposited in different oxygen volume fraction .The uniformity of diamond films quality was researched .The results indicate that the spectrum intensities of C2 ,CH and Hαdecrease with the oxygen volume fraction increasing .While the intensity ratios of C2 ,CH to Hαalso reduced as a function of increasing oxygen volume fraction .It is shown that the decrease of the absolute concentration of carbon radicals is attributed to the rise volume fraction of oxygen ,while the relative concentration of carbon radicals to hydrogen atom is also reducing ,which depressing the growth rate but improving the quality of diamond film .Furthermore ,the OH radicals ,role of etching ,its intensities increase with the increase of oxygen volume fraction .Indica‐ted that the improvement of OH concentration is also beneficial to reduce the content of amorphous carbon in diamond films .The spectrum space diagnosis results show that under high deposition pressure the distribution of the radicals in the CH4/H2/O2 plasma is inhomogeneous ,especially ,that of radical C2 gathered in the central region .And causing a rapid increase of non‐dia‐mond components in the central area ,eventually enable the uneven distribution of diamond films quality .

    • 摘要: CVD金刚石膜因其极高的强度和耐磨特性在微机电系统(MEMS)领域具有极好的应用前景,然而其极高的硬度和化学惰性又使其很难被加工成型,这极大地限制了CVD金刚石膜在MEMS领域的应用。本文主要介绍了近年来干法刻蚀图形化CVD金刚石膜的研究进展,系统地分析了激光刻蚀,等离子体刻蚀,等离子体辅助固体刻蚀的原理及其各自优缺点,着重论述了国内外采用等离子体刻蚀 CVD金刚石膜的研究现状。%CVD diamond film has great application prospect in micro-electro mechanical systems MEMS because of its excellent intensity and abrasion resistant properties but its practical application in MEMS is limited for its high hardness and chemically stable which makes it difficult to fabricate In this paper the latest developments of dry etching graphically progress of CVD diamond film is introduced and the principles of the laser etching plasma etching plasma-assisted etching of solid and their respective advantages and disadvantages are systematically analyzed Great attention is focused on the plasma etching of CVD diamond film in domestic and international.

    • 摘要: 在自主设计的具有非对称磁镜场位形的ECR等离子体装置上进行CVD金刚石膜的刻蚀实验,研究了基片温度、工作气压和磁场位形三个工艺参数对刻蚀效果的影响.实验结果表明:通过此方法刻蚀的CVD金刚石膜,其晶粒顶端被优先刻蚀,表面粗糙度降低.实际数据显示,刻蚀温度为20°C和150°C时,后者的刻蚀效果更好;工作气压为2×10-3 Pa和3×10-2 Pa时,前者的刻蚀效果更好;磁场强度为0.2T和0.15T时,前者的刻蚀效果更强.%CVD diamond films were etched by plasma on a self-developed electron cyclotron resonance (ECR) device. Influences of substrate temperature, working pressure and magnetic field configuration on etching effect were studied. Results showed that the top of the grain on CVD film was etched preferentially and that the- surface roughness Ra was reduced. The higher substrate temperature (150 °C compared with 20 °C ) , the lower working pressure (2 X 10-3 Pa compared with 3 X 10-2 Pa) , and the stronger magnetic field strength (0.2 T compared with 0. 15 T) contributed to a better etching effect.

    • 摘要: 利用Nd:YAG型金刚石精密激光切割机,采用激光轴向偏焦法对化学气相沉积(CVD)法制备的金刚石膜表面进行扫描式平整化处理,利用扫描电子显微镜(SEM)、粗糙度仪和金相显微镜对平整化后的金刚石表面进行表征,研究了激光充电电压和焦点位置对扫描凹槽宽度和深度的影响,以及扫描间距对平整化效果的影响.研究结果表明:扫描凹槽宽度随激光充电电压的升高而增大;凹槽深度随激光充电电压的升高而增大,随偏焦量的增大而增大.激光轴向偏焦法对CVD金刚石膜进行平整化处理后,其粗糙度显著减小,利用氢等离子体对其表面进行刻蚀处理,能够有效去除表层石墨,从而达到理想的平整化效果.%Inhomogeneous chemical vapor deposition (CVD) diamond thick films are flatted by a Nd:YAG laser cutting machine with axial offset-focus.The influences of laser voltage,laser frequency and focus position on the diameter and depth of scanning spot are researched respectively.In addition,the influence of scanning step on leveling result,which is characterized by a scanning electron microscope(SEM),a roughmeter and a optical microscope,is studied.The results show that the increase of laser voltage or focus offset contributes to the increase of depth of scanning spot,and the width of scanning groove will increase with the increase of laser voltage.The roughness of the CVD diamond films is reduced significantly after a flatting process,and the graphite on the surface of the diamond film due to laser processing is efficiently removed by etching of hydrogen plasma.
