Precise Surface Orientation Mapping with Omega-Scan

Even within a single crystal, slight variations in crystal orientation can occur across the surface, often due to internal strains from lattice defects. Similarly, well-grown thin films can display unique in-plane orientation distributions.

即便是同一塊單晶，其表面不同區(qū)域也可能存在晶體取向的細(xì)微偏差，這類偏差通常源于晶格缺陷引發(fā)的內(nèi)應(yīng)力。同理，生長狀態(tài)良好的薄膜也會呈現(xiàn)出獨(dú)特的面內(nèi)取向分布。

Mapping such surfaces typically requires numerous measurements, and this is where the Omega-Scan method excels with its speed and efficiency. The image below illustrates an orientation map measured on a (Si, Ge) solid solution wafer, where the maximum orientation difference is just 0.03°. The concentric circles in the map correspond to the crystal’s growth rings, providing valuable insights into its structure.

對這類晶體表面進(jìn)行取向測繪通常需要開展大量測量工作，而這正是Omega 掃描法的優(yōu)勢所在 —— 憑借其優(yōu)異的檢測速度與效率脫穎而出。

下方圖像展示的是一塊硅鍺固溶體晶圓的取向分布圖，該晶圓大的取向偏差只為 0.03°。圖中的同心圓與晶體的生長環(huán)一一對應(yīng)，為分析其晶體結(jié)構(gòu)提供了重要依據(jù)。

Advantages of the Omega-Scan Method

Omega-Scan 方法重要優(yōu)勢 （Freiberg Instruments 重要技術(shù)）：

---Stable and Simplified Setup

The X-ray tube and detector remain fixed, requiring only a single measuring circle and no monochromator.

穩(wěn)定便捷的安裝調(diào)試

X 射線管與探測器固定不動，只需單次測量周期，且無需單色儀。

---Comprehensive Data Collection

All necessary data for full orientation determination is captured in just one rotation.

全方面數(shù)據(jù)采集

單次旋轉(zhuǎn)即可采集全定向測定所需全部數(shù)據(jù)。

--High Precision with Minimal Measurement Time

The method delivers exceptional accuracy within a short measurement duration.

高精度?測量耗時(shí)短

短時(shí)間內(nèi)即可實(shí)現(xiàn)優(yōu)異精度。

These features make the Omega-Scan method particularly well-suited for routine measurements and industrial applications, where speed and reliability are essential.

憑借這些特性，Omega-Scan 方法尤為適配常規(guī)測量與工業(yè)應(yīng)用場景 —— 這類場景對速度與可靠性有著重要要求。

Understanding the Omega-Scan Method

解讀 Omega-Scan 方法

The Omega-Scan technique involves rotating the specimen 360° around a specific axis, such as the surface normal. The X-ray source and detector are positioned based on the crystal type to ensure an optimal number of reflections per turn. By analyzing the angular positions of these reflections, the crystal lattice orientation is determined in relation to the rotation axis.

Omega-Scan 技術(shù)的工作原理為：將試樣繞某一特定軸（如表面法線）完成 360° 旋轉(zhuǎn)，X 射線源與探測器則根據(jù)晶體類型進(jìn)行定位，以確保每圈旋轉(zhuǎn)均可獲得優(yōu)異的反射次數(shù)。通過分析這些反射信號的角度位置，即可確定晶格取向相對于旋轉(zhuǎn)軸的具體方位。

To precisely align the lattice orientation with the crystal surface, a laser beam checks the surface direction. Other relevant reference planes or directions can also be measured using optical tools. This technique enables accurate orientation measurement of single crystals in any configuration, achieving a reproducibility within a few arc seconds—often in just a few seconds of measurement.

為精確校準(zhǔn)晶格取向與晶體表面的對位關(guān)系，激光束會對晶體表面方向進(jìn)行檢測。其余相關(guān)參考平面或方向，亦可通過光學(xué)工具完成測量。

該技術(shù)可實(shí)現(xiàn)對任意形態(tài)單晶的高精度取向測量，重復(fù)性精度控制在數(shù)角秒范圍內(nèi) —— 且單次測量耗時(shí)通常只需數(shù)秒。

A specialized application of the Omega-Scan method is precision lattice-parameter determination, particularly for cubic crystals, providing highly accurate structural insights.
