Technical Field

The invention relates to the technical field of data processing, in particular to a scanning electrochemical microscope path planning method and device based on script analysis.

Background

Scanning Electrochemical Microscopy (SECM) is one type of microscope. Working on the electrochemical principle, the electrochemical current given by the oxidation or reduction of a substance in a micro-area can be measured. The highest resolution currently achievable is on the order of tens of nanometers, with very small electrodes (probes) driven to scan close to the sample, which can be a conductor, insulator or semiconductor, to obtain the corresponding micro-area electrochemistry and related information. The conventional secm uses ITO as a scanning substrate, modification and etching are carried out on the ITO, and the scanning probe microscope has a positive feedback mode and a negative feedback mode working mode, so that the conductive property of the substrate can be reflected through the current, and the despise imaging of the shape of the scanning substrate is realized.

The SECM can not only study heterogeneous reaction kinetics of the scanning probe and the substrate and homogeneous reaction kinetics in the solution, but also distinguish electrochemical nonuniformity of micro-regions on the surface of the electrode, give the appearance of the surface of a conductor and an insulator, even carry out micro-processing on materials, study a plurality of important biological processes and the like. SECM is a reality since it is being investigated for pharmacological release, phase transfer catalysis, dynamic processes, etc.

The scanning imaging is shown by thermodynamic diagrams, namely xy axis is a scanning area of the probe, z axis is the current intensity of the scanning area, and different current intensities can express the material property of the scanning substrate.

Microfabrication (micromachining technology): the scanning probe provides a fixed potential which can carry out oxidation and reduction reactions on the scanning substrate so as to complete the deposition and etching of the scanning substrate.

Script (script): is a sequence of instructions described in a particular programming language. Execution of the instructions is performed by the interpreter in a logical or sequential order.

Monochrome bitmap: there are pixel maps of only two colors, black and white.

Matrix: the image is described by a matrix, the rows and columns of the matrix represent the number of pixels in length and width on the image, and the value of the matrix is only 0 and 255, wherein 0 represents white and 255 represents black.

The existing scanning electrochemical microscope can only scan through a single path, such as an S-type scanning path and an E-type scanning path, and a user needs to set related experimental parameters in advance, and parameters such as a scanning moving direction, a moving distance, a moving speed, a displacement distance and the like for planning the S-type scanning path and the E-type scanning path, and the two scanning paths are relatively fixed and have low operation flexibility.

The following describes in detail the implementation process of the path planning method of the scanning electrochemical microscope according to the present invention with reference to the attached drawings: as shown in fig. 1:

1. the script can be graphically dragged or written by script writing software provided by the software. The scan path script is mainly used for primarily setting scan path parameters, including basic instructions and advanced instructions. Basic instructions include, but are not limited to, the following: the method comprises the steps of (1) a displacement instruction (go/back/left/right in micrometer) for moving the scanning probe up and down and left and right, a movement speed (speed in micrometer/second) of the motor and a displacement Increment of the motor, namely a movement Distance (Distance Increment in micrometer) of the motor, and Current Acquisition (Current Acquisition) for a scanning point when the scanning probe stays at the scanning point for a period (time in millisecond). Besides the basic command, a certain logic judgment command such as an IF-ElSE or a cycle command FOR, etc., a command FOR measuring the open-circuit potential of the working electrode or introducing other electrochemical experiment methods (such as performing other electrochemical experiments under a certain condition, but not constant potential experiments), and whether to disconnect the working electrode (on/off) is also provided.

2. If the user has self-defined scripts, the method analyzes the self-defined scripts of the user, firstly analyzes each script one by one, the written scripts generate corresponding instructions through semantic analysis, the instructions are executed in sequence, and finally the analyzed scripts generate a complete instruction sequence set under the electrode moving speed. And generating a related instruction sequence set, wherein the generated instruction sequence set is generally a combination of a basic instruction and a high-level instruction, generating related path planning and probe state parameters (generally parameters such as a moving step length, a retention time and an acquisition time) or experimental method information according to the generated instruction sequence set, and planning a system scanning path and controlling the probe state parameters so as to scan conveniently.

3. During micro-processing, path generation can be performed by adopting a monochrome bitmap. Since there are only black and white in a monochrome bitmap, black is considered to be the probe scan path. That is, only black needs to be recognized, and connecting black into a line is a scanning path. The monochrome bitmap is first parsed and the image is converted into a 2-valued two-dimensional matrix. As shown in fig. 2, in the conversion, black is 255 and white is 0, the length and width of the graph are obtained first, for example, the graph is a monochrome bitmap of 5 × 4 pixels, the graph can be converted into a two-dimensional matrix of 5 rows and 4 columns, each pixel corresponds to a value in the two-dimensional matrix, and the two-dimensional matrix after the analysis of the monochrome bitmap can be obtained. After the pixel pitch is set to be the pixel pitch, such as 5X4 pixels, which can be linked with the actual scanning area, if the pixel pitch is set to be 30 microns, the image is mapped to the actual distance position of 150 microns X120 microns ((5X30 microns) X (4X30 microns)). Parameters such as probe applied potential, applied potential time and the like can be set for describing a scanning path and a probe control method, the parameters are combined with a high-level instruction, the current collected by the probe can be used for judging the electrochemical corrosion or electrochemical deposition degree, the displacement position and the probe state of the scanning probe can be described by the method, a scanning instruction sequence set is finally generated, and the patterning function of the scanning electrochemical microscope is completed by executing the instruction sequence set.

4. The experiment was started and one of the three modes was selected for the experiment. After the experiment is finished, the experimental mode or script and experimental data are stored, so that a user can conveniently check the experimental mode or script and experimental data at any time in the later experimental process.

It will be appreciated that the conventional SECM provides a single scan path, with greater flexibility by performing the patterning process in a script or image fashion. On the premise of a known scanning path, different path planning algorithms can be introduced by adopting a script mode, conditions such as motor speed, displacement accuracy and the like can be intelligently planned through the path planning algorithms, the path of a complex image, such as a curve or a line segment with radian, can be more finely described, and further higher scanning and micro-processing accuracy is achieved.

The script solves the problem that the scanning path is too single in the experimental process. The method can control the scanning path of the probe according to the set script and plan and control the state of the probe according to the required scanning area.

In conclusion, the flexibility of the SECM scanning path is expanded, the conventional SECM scanning path is single, the patterning processing is carried out by introducing a script or image mode, the flexibility is high, different path planning algorithms are introduced on the premise of the known scanning path, parameters such as displacement precision, motor running speed and scanning probe staying time are intelligently regulated and controlled, and the scanning precision and the state control of the electrode are improved.
