Ion Beam Etching (or milling) is achieved by directing a beam of charged particles (ions) at a substrate with a suitably patterned mask in a high vacuum chamber. It enables highly-directional beams of neutral ions to control over the sidewall profile as well as radial …
Jan 01, 1984· Ion-Beam Etching (Milling) 347 active metal surface, which makes it more resistant to argon ion etching. Oxygen has the opposite effect on the etch rate of polymers such as photore sist [8]. Very rapid removal of resist occurs when a small amount of oxygen is added to the ion beam.
Aug 16, 2017· We present an argon ion beam milling process to remove the native oxide layer forming on aluminum thin films due to their exposure to atmosphere in between lithographic steps. Our cleaning process is readily integrable with conventional fabrication of Josephson junction quantum circuits.
Argon Ion Beam milling. Wet etching can often be damaging to samples, and for some materials there are no appropriate chemicals. In these cases Ion Beam milling can be used, which produces a cleaner etch profile and is more controllable and less damaging to delicate samples. The group possess a Millatron IV Argon Ion beam milling machine, a ...

High energy focused ion beam (FIB) milling produces ion-induced damage into TEM samples and a certain amount of Ga ions implantation cannot be avoided. Additional polishing of FIB lamellae at low voltages can damage the sample further. To overcome these disadvantages, a low-energy Ar +-milling of a FIB lamellae can be applied [1,2].In this work, we focus on TEM sample preparation of different ...
Jan 01, 2017· In this work we examine how microstructures can be reconstructed in three-dimensions (3D) by serial argon broad ion beam (BIB) milling, enabling much larger volumes (>250×250×100µm 3) to be acquired than by serial section focused ion beam-scanning electron microscopy (FIB-SEM).. The associated low level of damage introduced makes BIB milling very well suited to 3D-EBSD …
Figure 3 shows a schematic view of flat milling. In flat milling methods, an argon ion beam impinges on the sample surface at an angle and the axis of the beam is deflected from the sample rotation axis to allow processing of a wide sample area 3). The incident angle θ of the argon ion beam may be varied over the range 0° - 90° 4). If θ is ...

Ion milling of thin‐film GaN, InN, AlN, and InGaN was performed with 100–500 eV Ar + ions at beam angles of incidence ranging from 0° to 75° from normal incidence. The mill rates normalized to the Ar + beam current for the single‐crystal GaN, AlN, and InGaN were typically a factor of 2 lower than for GaAs and InP. For the polycrystalline InN, the mill rates were similar to those of ...
