12624 化学钝化方法主要包括各向同性的氢氟酸(HF)腐蚀钝化和各向异性的四甲基氢氧化铵(TMAH)腐蚀钝化。 The chemical passivation methods mainly include the hydrofluoric acid ( HF ) isotropic etching and tetramethyl-ammonium-hydroxide (TMAH) anisotropic etching.
12625 HF钝化方法以氢饱 和硅表面悬挂键来减少其表面界面态，TMAH钝化方法则通过各向异性腐蚀形成Si—O键。 The HF passivation method can saturate the dangling bonds of the silicon surface with hydrogen to reduce its surface interface states. The TMAH passivation method can form Si——O bonds by anisotropic etching.

12628 采用微波等离子体化学气相沉积(MPCVD)法同质生长了边缘无多晶聚集的金刚石，详细研究了其表面与侧面的生长情况％利用微分干涉相差显微镜和喇曼光谱仪对边缘无多晶的单晶金刚石进行了表征。 Single crystal diamond without any polycrystal on the lateral faces was successfully grown on a homogeneous diamond seed by microwave plasma chemical vapor deposition ( MPCVD) method，and the morphological evolution on the surface and lateral faces of the as-grown diamond was carefully investigated. The single crystal diamond without any polycrystal on the lateral faces was characterized by differential interference contrast microscope and Raman spectrometers.
12629 结果表明，通过优化侧面温度的控制可以实现4个侧面呈单晶生长，生长结束后金刚石尺寸由原始的3.50 mmX3. 50 mm扩展到4.50 mmX4. 52 mm，并且侧面扩展部分与 表面区域的喇曼特征峰半高宽均在2.2〜2.4 cm1I附近，呈现出较高的结晶质量，而光致发光光 谱测试结果表明，晶体内部有氮和硅杂质存在。 The results show that by optimizing the control of temperature，the growth of single crystal diamond was realized on the four lateral faces and the size of the as-grown diamond was increased from originally 3. 50 mmX 3. 50 mm to 4. 50 mm X 4. 52 mm after growth. The full width at half maximum (1 WHMs) of Raman characteristic peaks on four lateral enlarged faces and the top surface are approximately 2. 2-2. 4 cm-1，indicating a superior crystalline quality of diamond. However，photoluminescence spectra test result demonstrates the existence of nitrogen and silicon impurities in the as-grown diamond.
12630 对于金刚石同质生长而言，金刚石4个侧面同时 生长将会提高单晶生长效率和金刚石单片尺寸。 For diamond homogeneous growth, simultaneous growth of the four lateral faces of the diamond will increase single crystal diamond growth efficiency and size of the diamond chip.
