- Adjustment parameters may include the emission current of the ion source, the energy of the ions, the focusing of the ion beam, the amplitude of the writing field on the substrate, the correction of stigmatism and the distance between the device and the substrate.
- This device 2 comprises an ion source 4, for example with liquid metal, which is intended to produce an ion beam, for example formed of gallium ions, a system 6 for extracting and accelerating the ion beam product, a source support 8 and an electrostatic optical system 10.
- ion source 4 for example with liquid metal
- a system 6 for extracting and accelerating the ion beam product
- a source support 8 and an electrostatic optical system 10.
- Zl the axis of this system 10 and Z the axis of the ion beam 12 emitted by the source 4
- the axes Z and Zl being parallel .
- the assembly formed by the source 4, its support 8 and the system 10 constitutes the focused ion column of the apparatus 2.
- the system 10 essentially consists of electrostatic lenses (not shown) in order to focus the beam 12, to form a focused ion beam 14.
- the source support is provided with a set 16 of micrometric plates. This set 16, symbolized by mixed lines in the figure, allows the support 8 along an X axis and a Y axis which are perpendicular to each other and to the Z axis.
- the figure also shows a substrate 18 intended to be treated by the focused beam 14 and constituting a target for this beam (which is capable of eroding this substrate 18).
- This substrate is mounted on a plate 20 which can be moved along three axes respectively perpendicular to the axes X, Y and Z.
- the apparatus 2 is intended to fabricate a nanostructure on the substrate 18.
- This system 22 includes:
- means 24 for controlling the ion source 4 means 26 for controlling the system 6 for extracting and accelerating the ion beam 12, means for controlling the system 10 for electrostatic optics, and
- the calibration structures generally gold markers on silicon which are conventionally used for example in electron beam lithography.
- the duration of use of the ion beam can reach several hours, which makes it necessary to periodically check the characteristics of this ion beam to limit the influence of drifts and transient instabilities.
- This difference in optical path causes the appearance of faults or aberrations.
- the writing size is limited in a field of the order of a hundred micrometers.
- the nano-fabrication technique by FIB can only form small elementary patterns.
- the possibility of connecting several elementary substructures to define a larger pattern appears. But this remains subject to a rigorous calibration of the size of the elementary writing field by FIB.
- any variation in the distance between the substrate and the ion column, in the energy of the ions or in the nature of the latter changes the value of the amplitude of the scanning field.
- the technique considered is rapid, very precise and capable of being automated for calibrating the optical system 10 of the ion column, using the property that heavy incident ions have, such as gallium ions or other metals for example. aluminum, to locally burn the target they hit.
- the same ion beam generation device is capable of forming its own calibration marks and then verifying them in complete autonomy.
- the technique considered uses the effect of erosion of the incident ion beam, generated by the ion beam generation apparatus 2, to engrave a simple structure, according to a pattern predetermined by CAD, for example of the square type, single hole ("spot") or cross, in a "sacrificed" area.
- this structure is then imaged by the device 2 which is then operated in MIB or Scanning Ionic Microscopy mode, under the same conditions, without any modification, by simply collecting, using appropriate detection means 32, the secondary electrons 34 which result from the scanning of the surface of the substrate 18 by the ion beam 14.
- Electronic processing means 36 provided with display means 38, are provided for processing the signals supplied by these detection means 32.
- the MIB image obtained by the detection means is digitized by the electronic processing means 36 and, on this digitized MIB image; corresponding to the structure actually engraved, it is then possible to computerize the initial predetermined digitized pattern (square, hole or cross for example) and to differentiate (numerically) the two images. In the case of a square type pattern for example, it is then possible to detect a defect originating from poor focusing and then to remedy it by increasing step by step the focusing effect of the lenses of the beam generation apparatus 2. The process can be automated for different magnifications and repeated step by step, until the scanned MIB image and the original pattern coincide perfectly.
- the ion beam is kept in "spot” mode and does not scan the surface of the substrate 18 while the latter is moved by means of the plate 20 which supports this substrate, measuring the displacements of this platinum being performed by laser interferometry. Mechanical precision can then drop to a few nanometers (of the order of 10 nm to 5 nm).
- the markers are formed not by scanning the surface of the target 18 by the ion probe 14 but only by moving this target, the central axis Z1 of the etching ion beam being kept fixed.
- An MIB image of the structures thus produced then makes it possible, after digitization of this image, to adjust the gain of the amplifier stage of the beam generation apparatus 2 so that a digital weight of 1 or a few bits corresponds to a known displacement (of a certain number of nanometers) at the level of the substrate 18.
- the calibration of the scanning field is then carried out with a measurement technique by laser interferometry.
- a device which is complementary to the technique considered above and which reinforces it.
- the proposed device aims in particular to improve and make more effective the adjustment of the parameters of an ion column delivering an ion probe on the scale of ten nanometers, with a view to forming nanometer-sized structures by controlled ion irradiation.
- the user of a device for generating a beam of charged particles, and more particularly of an ion beam is offered different levels of assistance:
- the beam generation device can perform its own calibration marks and then image them by scanning ion microscopy.
- the system 22 is completed by an adjustment module 40 or calculation module.
- This module 40 essentially comprising a computer, provides information to the operator
- the adjustment module 40 is connected to the various control means 24, 26, 28, 29 and 30 that the system includes.
- the module 40 is connected to the detection means 32 and to the electronic processing means 36 in order to control the operation of the apparatus in scanning ion microscopy mode and to exploit the results of this operation. According to the invention, adjustments are proposed to the operator, these adjustments being determined by the calculation module. Then the operator begins the nano-manufacturing sequence.
- the module 40 calculates permanently (or periodically but then with a high frequency) the properties of the ion probe (ion beam 14) during this nano-fabrication sequence and compares the result of the calculation with pre-established values, stored in this module 40. If the values obtained during the calculation are different from these pre-established values, the module undertakes correction measures by adjusting the adjustment parameters of the device or, if the difference between the results of the calculation and the preset values is too important, the module 40 informs the operator via the display means 38.
- the adjustment module 40 stores the desired characteristics for the ion beam 14, determined beforehand by the user of the device 2 as a function of the structure to be produced on the substrate 18.
- the module 40 determines the values of the adjustment parameters of the apparatus 2 as a function of these characteristics and stores these values.
- the module gives these values, which it has memorized, to the adjustment parameters of the device 2 via the control means 24, 26, 28 and 30, to which the module 40 sends control signals making it possible to make the desired settings.
- the characteristics of the ion beam 14 are the size of this ion beam and the current density in this beam.
- the ion column adjustment parameters are as follows:
- the module 40 can measure these parameters permanently or periodically (preferably with a high frequency) and determine the characteristics of the beam 14 from these measurements (which are made by through means 24, 26, 28 and 30).
- the module compares the characteristics thus determined with the memorized characteristics. When one or more of the characteristics thus determined differ (by a predefined percentage, ranging for example from -10% to + 10%) from the corresponding characteristic or memorized characteristics, the module warns the operator and modifies the adjustment parameters again to obtain the correct characteristics for beam 14.
- the module 40 can simply warn the operator and wait for instructions from the latter to continue manufacturing.
- the module 40 can implement the following steps: • This module controls the device 2 to form on the substrate 18, in an area of this substrate which is not intended for the formation of the structure, a test fingerprint in accordance with a reference digital fingerprint previously stored in the module 40. • The module then compares the digital test fingerprint with the stored digital reference fingerprint.
- the module modifies one or more of the adjustment parameters of the device 2 and repeats the steps considered until obtaining a suitable setting for this device.
- the module 40 can be programmed to act on the device (via the control means 24, 26 and 28 in the event of one or more of the parameters drifting. It should in fact be noted that a manufacturing sequence generally lasts a long time, for example 2 hours.
- the module 40 is capable of measuring the parameters (permanently or periodically), it can detect the drift of these and remedy them.
- module 40 can be programmed to interrupt the production sequence (and inform the operator) in the event of instability of one or more parameters, i.e. in the event of a variation brutal of these.
- the module 40 provision can be made for the module 40 to start a calibration phase of the apparatus 2, according to a technique mentioned above, which uses the formation of patterns (for example crosses or holes) in an area of the substrate 18 where we don't form the structure. It should be noted that the calibration is done without requiring operator intervention.
- the module itself controls the production of the etchings required in the substrate 18 in order to adjust the parameter (s) again, the module 40 modifying the latter or the latter until a suitable adjustment is obtained.
- nano-fabrication takes place at very low pressure; for one reason or another, this pressure can increase very quickly; similarly, a problem of an electrical nature is likely to affect the device 2; in such cases, the module 40 cannot act alone and the intervention of the operator is necessary.
- the present invention is not limited to the adjustment of an apparatus for generating an ion beam (positive or negative). It also applies to the adjustment of other devices for generating charged particle beams such as electron microscopes, the particles then being electrons.
