  • The development of the femtosecond laser (fs laser) with its ability to provide extremely rapid athermal ablation of materials has initiated a renaissance in materials science. Sample milling rates for the fs laser are orders of magnitude greater than that of traditional focused ion beam (FIB) sources currently used. In combination with minimal surface post-processing requirements, this technology is proving to be a game changer for materials research. The development of a femtosecond laser attached to a focused ion beam scanning electron microscope (LaserFIB) enables numerous new capabilities, including access to deeply buried structures as well as the production of extremely large trenches, cross sections, pillars and TEM H-bars, all while preserving microstructure and avoiding or reducing FIB polishing. Several high impact applications are now possible due to this technology in the fields of crystallography, electronics, mechanical engineering, battery research and materials sample preparation. This review article summarizes the current opportunities for this new technology focusing on the materials science megatrends of engineering materials, energy materials and electronics.

  • TEM(Transmission Electrion microsopy) 투과전자현미경은 재료의 기초 구조 분석과 반도체 또는 생물시편의 미세 구조분석에 널리 사용되는 장비이다. TEM 분석은 필수적으로 목적에 부합되는 적절한 시편제작이 수반되어야 한다. 다양한 전자 현미경 시편 제작 방법 중 본 논문에서는 FIB(Focus Ion Beam)를 이용한 시편 제작법 중 시편에 입사되는 에너지와 이온 Gun과 시편과의 상호 각도, 이온 밀링 깊이 조절 등의 실험을 통하여 표면 손상 최소화를 벌크 웨이퍼와 패턴화된 시편에서 실험하였다. 최소화된 표면 영향성(약 5nm)을 패턴화된 시편에 구현하였다.

  • A procedure for preparing cross-sectional specimens for transmission electron microscopy(TEM)by focused ion beam(FIB)milling of specific regions of semiconductor devices is outlined. This technique enables TEM specimens to be pripared at precisely preselected area. In-situ #W thin film deposition on the top surface of desired site is complementally used to secure the TEM specimens to be less wedge shaped, which is main shortcoming of previous FIB-assisted TEM sample preparation technique. This technique is quite useful for the TEM sample priparation for fault finding and the characterization of fabrication process associated with submicron contact technologies.

  • 후방산란전자(BSE)는 입사전자빔이 시료와 충돌하면서 발생한다. BSE 이미징은 시료의 화학적 특성을 구분할 수 있는 조성대비를 제공한다. 집속이온빔장치(FIB)는 전계방사형 주사전자현미경(FESEM)과 결합할 수 있으므로 이중빔 체계(FIB-FESEM)가 구현된다. 갈륨(Ga) 이온빔으로 10~100 nm 두께로 시료를 절삭할 수 있으므로 FIB-FESEM은 플라스틱으로 포매된 블록의 면을 z축 고해상도를 유지하며 연속적으로 이미징할 수 있다. BSE이미지의 대비를 반전시키면 투과전자현미경의 이미지와 유사하다. 연속블록면 이미징의 또 다른 방안으로써 특수한 초박절편기가 FESEM 내부에 장착된 것이 $3View^{(R)}$로 상용화되어 있다. 이로써 플라스틱으로 포매된 시료의 내부 구조를 넓은 면적을 연속적으로 이미징 할 수 있으므로 3차원 재구성도 용이하게 된다. 이러한 FESEM에 기반한 두 가지 방식은 복잡한 생물계의 총체적인 이해를 위하여 세포 및 세포 수준 이하의 구조물 간의 공간적 연관성을 규명하는 데 활용될 수 있다.

  • For the measurements of surface shape milled using FIB (focused ion beam), the silicon bulk, $Si_3N_4/Si$, and Al/Si samples are used and observed the shapes milled from different sputtering rates, incident angles of $Ga^+$ ions bombardment, beam current, and target material. These conditions also can be influenced the sputtering rate, raster image, and milled shape. The fundamental ion-solid interactions of FIB milling are discussed and explained using TRIM programs (SRIM, TC, and T-dyn). The damaged layers caused by bombarding of $Ga^+$ ions were observed on the surface of target materials. The simulated results were shown a little bit deviation with the experimental data due to relatively small sputtering rate on the sample surface. The simulation results showed about 10.6% tolerance from the measured data at 200 pA. On the other hand, the improved analytical model of damaged layer was matched well with experimental XTEM (cross-sectional transmission electron microscopy) data.

  • The residual stress in axial stress in the axial direction of the steel filaments has been measured by using a method based on the combination of the focused ion beam (FIB) and high resolution strain mapping program (VIC-2D). That is, the residual stress was calculated from the measured displacement field before and after the introduction of a slot along the steel filaments. The displacement was obtained by the digital correlation analysis of high-resolution scanning electron micrographs, while the slot was introduced by FIB milling with low energy beam. The present measurement revealed that the residual stress within 8% of the magnitude was persistent in the steel filaments fabricated.
