Abstract

Soft X-ray holography is a recently developed imaging technique with sub-50 nm spatial resolution. Key advantages of this technique are magnetic and elemental sensitivity, compatibility with imaging at free electron laser facilities, and immunity to in-situ sample excitations and sample drift, which enables the reliable detection of relative changes between two images with a precision of a few nanometers. In X-ray holography, the main part of the experimental setup is integrated in the sample, which consequently requires a large number of fabrication steps. Here we present a generic design and an automatable fabrication process for samples suitable, and optimized for, efficient high resolution X-ray holographic dynamic imaging. The high efficiency of the design facilitates the acquisition of magnetic images in a few minutes and makes fully automatic image reconstruction possible.

Fig. 1

Sample fabrication steps for pump-probe X-ray holography. (a) Si frame (gray) with Si3N4 membrane (transparent green) and extra Si3N4 coating on the back side. (b) Deposition of a Cr/Au multilayer on the back of the membrane. (c) FIB milling of an 800 nm diameter object hole in the Cr/Au film. (d) EBL definition of aligned markers on the flat membrane. (e) Preparation of a magnetic specimen (here: a disk) on the top side of the sample, aligned with respect to the center of the object hole (after film deposition, EBL etch mask fabrication, and Ar milling). (f) EBL fabrication of the microcoil around the magnetic disk. (g) Local removal of the Si3N4 for the reference milling by FIB. (h) FIB milling of the reference holes in the Cr/Au multilayer.

Scanning electron micrographs of the object hole milled into the Cr/Au layer. (a) View under 30° with respect to the surface normal, showing the Cr/Au multilayer stack (Au appears bright, Cr gray, and Si3N4 black). (b) Vertical cross section. The object hole is visible as an horizontal interruption of the periodic Cr/Au multilayers. A dust particle has fallen on the object hole before the preparation of the lamella.

Fig. 3
Fig. 3

Magnetic disk. (a) SEM view of the top side of the Si3N4 membrane. The membrane is visible as a bright rectangle due to electron backscattering from the Au layer underneath. The object hole is visible as a dark circle around the magnetic disk. (b) TEM image of a vertical cross section, which is a zoom-in of the area shown in Fig. 2(b).

Fig. 4
Fig. 4

SEM images of the final fabrication steps. (a) Cross section through a 330 nm wide line defining a mask in 750 nm thick PMMA for the Au microcoil deposition. The variation of the width of the line as a function of vertical position is negligible, i.e., the PMMA walls have no undercut. (b) Image of the final sample before preparation of the second reference. The sample is tilted by 52° with respect to the incident electron beam. The image shows the magnetic disk in the center, which is tightly surrounded by a Au microcoil. In this particular sample, three areas of Si3N4 are removed to prepare the references where one reference has already been prepared with the cone on the top side (the side from which the image was taken). (c) Top-view of the same sample after the preparation of another reference from the bottom side.

Fig. 5

Holographic reconstructions of a magnetic state obtained with the presented sample design. (a) Topography of the specimen, which is a 550 nm diameter disk with a notch at the top centered to the 800 nm diameter field of view defined by the object hole (white circle). (b) Reconstruction of the magnetic state from a difference hologram with 6 × 107 photons per helicity, cropped to the disk area. The magnetization is pointing downwards (away from the reader) in the white regions, whereas it is pointing upwards in the black areas. The image shows a magnetic configuration with two bubble domains. (c) Reconstruction of the same state from 1.3 × 107 photons per helicity. The orientation of the magnetic domains is depicted on top on the image in a schematic cross section through the disk.
