[0002] In the production process of semiconductor machines, it is usually necessary to adjust multiple power supplies so that the generated ion flow intensity meets the process requirements. Since there is no definite correspondence between the power supply parameter settings and the detected ion flow intensity, in order to find the voltage or current setting value that meets the requirements, the currently commonly used optimization method is the traditional curve fitting method, that is, measuring the ion flow intensity value corresponding to the power supply parameters point by point, and after obtaining enough sample points, determining the optimal power supply parameters by fitting the curve.

[0003] However, this method has obvious shortcomings: too many measurements, each measuring point needs to be tested one by one, which takes a lot of time and reduces the production efficiency of the machine; insufficient adaptability, the measurement process takes a long time to cover the entire parameter range, and it is difficult to quickly adapt to changing process conditions.

[0004] Accordingly, the art needs a new power parameter adjustment solution to solve the above problems. Summary of the invention

[0015] x i =x L +R×(x H -x L ),

[0016] x j =x L +(1-R)×(x H -x L ), where R<0.5.

[0017] In a technical solution of the above power supply parameter adjustment method, if the first measuring point x is measured i and the second measuring point x j The corresponding measured values ​​are y i ,y j , the comparing the measurement values ​​corresponding to the first measuring point and the second measuring point, and narrowing the power supply parameter search range based on the comparison result to generate a new power supply parameter search range, includes:

[0018] If y i >y j , then the new power supply parameter search range is [x L ,x j ];

[0019] If y i <y j , then the new power supply parameter search range is [x i ,x H ].

[0020] In a technical solution of the above power supply parameter adjustment method, the method further includes:

[0021] If y i >y j , then the new power supply parameter search range is [x L ,x j ], x iAs a test point for a new round of search;

[0023] In a technical solution of the above power parameter adjustment method, the first measuring point and the second measuring point are re-determined based on the new power parameter search range and the optimization parameter, and the above steps are repeated until a preset search exit condition is met, including:

[0024] When the power parameter search range is smaller than a preset threshold, or

[0025] When the difference between the power parameter search ranges of two consecutive searches is less than a preset difference, the search ends.

[0026] In a technical solution of the above power parameter adjustment method, the outputting of the power parameter satisfying the search exit condition as the target power parameter value includes:

[0027] According to the power parameter search range corresponding to the search end, the target power parameter value is obtained.

[0028] In one technical solution of the power supply parameter adjustment method, the semiconductor machine includes a plurality of power supplies.

[0029] For each power supply, the power supply parameters are adjusted based on the method described in any one of the technical solutions of the power supply parameter adjustment method to obtain the corresponding target power supply parameter value.

[0048] In the semiconductor manufacturing process, ion implantation equipment is required to implant specific ions into semiconductor materials. This process can control the electrical properties of the material and is a key step in the preparation process.

[0049] The invention provides a power supply parameter adjustment method, which is applied to a semiconductor machine.

[0050] See also Figure 1 , Figure 1 FIG. 1 is a flow chart of the main steps of a power supply parameter adjustment method according to an embodiment of the present invention. Figure 1 As shown, the power parameter adjustment method in the embodiment of the present invention mainly includes the following steps S1 to S6.

[0051] Step S1, obtaining an initial power supply parameter search range and optimization parameters.

[0052] In one embodiment of the present invention, the initial power parameter search range may be a parameter accepted by an operator or may be pre-stored in a database; the optimization parameters are pre-stored in a database. Exemplarily, the initial power parameter search range is [x L ,x H ], the optimization parameter is R.

[0053] In one embodiment, the initial power parameter search range [x L ,x H ] is the adjustable range of the power supply parameters of the semiconductor machine. The optimization parameter R is used to control the shrinking speed of the search range in each iteration, and can be set and adjusted according to historical data and pre-stored in the database for use.

[0054] Furthermore, in one embodiment of the present invention, the power supply parameter is a current or voltage parameter of the power supply. In the ion implantation process, those skilled in the art can obtain the expected ion current intensity by setting the current or voltage parameter of the semiconductor machine.

[0055] Step S2: determining a first measuring point and a second measuring point of the power supply parameter based on the initial power supply parameter search range and the optimization parameter.

[0056] In one embodiment of the present invention, the determining of the first and second measuring points of the power supply parameters based on the initial power supply parameter search range and the optimization parameter includes:

[0057] When the power supply parameter search range is [x L ,x H ], when the optimization parameter is R, the first measuring point x is obtained based on the following formula i and the second measuring point x j :

[0058] x i =x L +R×(x H -x L ),

[0059] x j =x L +(1-R)×(x H -x L ), where R<0.5.

[0060] Step S3: obtaining measurement values ​​corresponding to the first measuring point and the second measuring point from a measuring device.

[0061] In one embodiment, the measuring device is a Faraday cup; and the measured value is an ion current intensity value.

[0062] Step S4: comparing the measurement values ​​corresponding to the first measurement point and the second measurement point, and narrowing the power supply parameter search range based on the comparison result to generate a new power supply parameter search range.

[0063] In one embodiment of the present invention, if the first measuring point x is measured i and the second measuring point x j The corresponding measured values ​​are y i ,y j , the comparing the measurement values ​​corresponding to the first measuring point and the second measuring point, and narrowing the power supply parameter search range based on the comparison result to generate a new power supply parameter search range, includes:

[0064] If y i >yj , then the new power supply parameter search range is [x L ,x j ].

[0065] This means that at the measuring point x i The current intensity is higher at , so we can infer that the optimal measurement value is in the interval [x L ,x j ] in x. j The intensity at is low, indicating that the maximum value may be in the area to its left.

[0066] If y i >y j , then the new power supply parameter search range is [x L ,x j ], x i As a measurement point for the next round of search. Use this interval as the range for the next search, while keeping x i As the next measurement point, the search efficiency can be improved.

[0067] If y i <y j , then the new power supply parameter search range is [x i ,x H ].

[0068] In this case, based on the inference that the maximum value can only appear on one side, the optimal measurement value may be in the interval [x i ,x H ] At this time, if y i <y j , then the new power supply parameter search range is [x i ,x H ], x j As a test point for a new round of search.

[0069] Step S5, based on the new power parameter search range and the optimization parameters, re-determine the first measuring point and the second measuring point, and loop through steps S3 to S4 until a preset search exit condition is met.

[0070] In one embodiment of the present invention, the first measuring point and the second measuring point are re-determined based on the new power parameter search range and the optimization parameter, and the above steps are repeated until a preset search exit condition is met, including:

[0071] When the power parameter search range is smaller than a preset threshold, or

[0072] When the difference between the power parameter search ranges of two consecutive searches is less than a preset difference, the search ends.

[0073] During the iteration process, the search range continues to shrink. When the power parameter search range is smaller than a preset threshold, it can be considered that the search range is small enough. When the difference between the power parameter search ranges of two adjacent searches is smaller than a preset difference, the search results can be considered stable. When any of the above conditions is met, the search can be terminated.

[0074] The method utilizes the single-peak characteristic of the function, gradually narrows the search range, avoids invalid measurements and unnecessary test points, and thus improves efficiency.

[0075] Step S6, outputting the power parameter that meets the search exit condition as the target power parameter value.

[0076] In one embodiment of the present invention, outputting the power parameter that meets the search exit condition as the target power parameter value includes: acquiring the target power parameter value according to a power parameter search range corresponding to the end of the search.

[0077] Exemplarily, the interval midpoint method may be used to calculate the midpoint of the power parameter search range corresponding to the end of the search as the target power parameter value.

[0078] In one embodiment, the preset difference is 0.001 (mA).

[0079] The initial power supply parameter search range is [8mA, 12mA], and the optimization parameter R is 0.35.

[0080] First search:

[0081] x i =8+0.35×(12-8)=9.4mA;

[0082] x j =8+(1-0.35)×(12-8)=10.6mA;

[0083] Measured y i =10.1mA,y j =9.8mA;

[0084] Because of y i >y j , then the next search range is [8,10.6], and the measurement point 9.4mA is retained.

[0085] Second search, calculate new measurement points:

[0086] x i ' = 9.4mA;

[0087] x j'=8+(1-0.35)×(10.6-8)=10.0mA;

[0088] Measured y i '=10.1mA,y j '=10.2mA;

[0089] Because of y i ' <y j ', then the next search range is [9.4,10.6], and the measurement point 10.0mA is retained.

[0090] Subsequent searches continue to iterate, and when the range difference between the 15th search and the 14th search is less than the preset difference of 0.001 mA, the search ends (at this time the power parameter search range is not less than the preset threshold), and the midpoint of the current search range is obtained as the target power parameter value.

[0091] After obtaining the target power parameter value, the power parameter is set to the target power parameter value to obtain the maximum ion current intensity.

[0092] In a technical solution of the above power parameter adjustment method, the semiconductor machine includes multiple power supplies, wherein for each power supply, the power supply parameter is adjusted based on the method described in any technical solution of the above power parameter adjustment method to obtain a corresponding target power parameter value.

[0093] In actual applications, each power source is optimized individually to achieve the overall goal. Through individual optimization, the settings of each power source can be adjusted more accurately to ensure that the overall current intensity meets the recipe requirements. By adjusting the power supply parameters through the method in the above technical solution, multiple power sources work together to produce an ion flow that meets the process requirements.

[0094] Based on the method described in steps S1 to S6 above, by gradually narrowing the search range, only two measuring points are needed each time to complete the optimization; by using a recursive iteration method and setting reasonable exit conditions; the number of measurements is greatly reduced, the measurement time is effectively reduced, and it is ensured that the final search range converges to the vicinity of the target value, so that a more accurate target power supply parameter value can be obtained.

[0095] The above technical solution is used to find the power supply parameters for obtaining the maximum ion flow. In other technical solutions of the present application, after adjusting the corresponding relationship for narrowing the search range of the power supply parameters based on the comparison result, the above method can also be used to find the power supply parameters for the minimum ion flow. The method is applicable to both the case of maximizing the ion flow intensity and the case of minimizing the ion flow intensity, and has wide applicability.

[0096] The power parameter adjustment method in the above technical solution can be manually adjusted by a technician to set the power supply, and gradually set, measure and record the results, or it can be automatically completed through computer control.

[0097] In an application scenario according to an embodiment of the present invention, automated control can be performed by combining with a semiconductor machine system to further improve production efficiency and accuracy without relying on too much historical data or complex modeling. Adjustments only need to be made based on real-time measurements, which is suitable for actual applications in semiconductor production lines.
