The described embodiments should not be regarded as limitations on this application. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0052] In the following description, references are made to “some embodiments,” which describe a subset of all possible embodiments. However, it is understood that “some embodiments” may be the same subset or different subsets of all possible embodiments and may be combined with each other without conflict.
[0053] In the following description, the terms "first" and "second" are used merely to distinguish similar objects and do not represent a specific ordering of objects. It is understood that "first" and "second" may be interchanged in a specific order or sequence where permitted, so that the embodiments of this application described herein can be implemented in an order other than that illustrated or described herein.
[0054] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.
[0055] It should be understood that in the various embodiments of this application, the sequence number of each implementation process does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.
[0056] In existing technologies, ion implantation into semiconductor structures generates a channeling effect. To avoid this effect, ion implantation is typically performed at a specific angle. During chip fabrication, photoresist is applied to the surface of the semiconductor structure; the presence of photoresist causes the ion implantation position to deviate from the initially designed position. This change in ion implantation position will affect the semiconductor structure.
[0057] A schematic diagram of the CMOS model, as shown below. Figure 1 As shown, the positions of the source, gate, and drain in CMOS need to be pre-designed, and the source, gate, and drain are all formed by ion implantation.
[0058] A schematic diagram of CMOS fabrication, such as Figure 2 As shown, photoresist can block ion implantation and protect the structure beneath it; ions will be implanted into the surface of the structure that is not covered by photoresist, and the desired semiconductor device can be fabricated by implanting ions into the surface of the structure.
[0059] A schematic diagram of ion implantation at a certain angle in the prior art, such as... Figure 3 As shown, due to the presence of photoresist, there is a region on the surface of the structure that cannot be implanted with ions; this region is called the ion-implantation-blocking region. Figure 3 Region 1. Due to the presence of photoresist, there will be a region on the structure surface that should not have been implanted with ions, but has been implanted with ions. This region is called the over-implanted ion region, such as... Figure 3 Region 2. Both regions that block ion implantation and regions that over-implant ions will make the linewidth of the structure or device uncontrollable. Especially for high-end processes below 10nm, these regions will affect the actual position of the channel, causing deviations in the structure or device.
[0060] Based on this, embodiments of this application provide a method for determining photoresist parameters in an ion implantation process. A schematic diagram of an optional processing flow for the method of determining photoresist parameters in an ion implantation process provided in embodiments of this application is shown below. Figure 4 As shown, it includes at least the following steps:
[0061] Step S101: Determine the height of the photoresist, the angle of ion implantation, and the depth of ion implantation.
[0062] In some embodiments, the height of the photoresist covering the surface of the structure, the angle of ion implantation, and the depth of ion implantation can be determined based on the structure being fabricated or the device to which the structure is applied. The specific implementation process for determining the height of the photoresist, the angle of ion implantation, and the depth of ion implantation is the same as in the prior art and will not be described in detail here.
[0063] Step S102: Based on the height of the photoresist and the angle of ion implantation, determine the first width of the region blocking ion implantation.
[0064] In some embodiments, the specific implementation process for determining the first width of the region blocking ion implantation based on the height of the photoresist and the angle of ion implantation can be as follows: Figure 5 As shown, it includes at least the following steps:
[0065] Step S1021: Calculate the product of the tangent of the ion implantation angle and the photoresist height.
[0066] Step S1022: The product of the tangent of the ion implantation angle and the photoresist height is determined as the first width.
[0067] The ion implantation angle and photoresist height have been determined in step S101. By calculating the product of the tangent of the ion implantation angle and the photoresist height, the first width of the region blocking ion implantation can be obtained.
[0068] In this embodiment of the application, if the ion implantation angle is θ, the photoresist height is t, and the first width is L1, then the first width can be represented by the following formula (1):
[0069] L1=t*tanθ(1)
[0070] Step S103: Based on the ion implantation angle and the ion implantation depth, determine the second width of the region over-implanted ions.
[0071] In some embodiments, the specific implementation process for determining the second width of the over-implanted ion region based on the ion implantation angle and the ion implantation depth can be as follows: Figure 6 As shown, it includes at least the following steps:
[0072] Step S1031: Calculate the product of the tangent of the ion implantation angle and the ion implantation depth.
[0073] Step S1032: The product of the tangent of the ion implantation angle and the ion implantation depth is determined as the second width.
[0074] The ion implantation angle and ion implantation depth have been determined in step S101. By calculating the product of the tangent of the ion implantation angle and the ion implantation depth, the second width of the region over-implanted with ions can be obtained.
[0075] In this embodiment of the application, if the ion implantation angle is θ, the ion implantation depth is H, and the second width is L2, then the first width can be represented by the following formula (2):
[0076] L2=H*tanθ(2)
[0077] Step S104: Determine the target position of the photoresist in the structure to be ion implanted based on the first width and the second width.
[0078] In some embodiments, the specific implementation process of determining the target position of the photoresist in the structure to be ion implanted based on the first width and the second width is as follows: Figure 7 As shown, it includes at least the following steps:
[0079] Step S1041: Determine the target first coordinate of the photoresist in the horizontal direction as the preset first coordinate of the photoresist in the horizontal direction and the second width.
[0080] In some embodiments, the preset first coordinate of the photoresist in the horizontal direction is: the coordinate closest to the origin among two coordinates characterizing the horizontal position of the photoresist, with the structural surface covered by the photoresist as the X-axis. The preset first coordinate is a coordinate predetermined without considering the influence of the photoresist on ion implantation.
[0081] If the first coordinate is preset to X0, then the first coordinate of the target is X0-L2.
[0082] Step S1042: Determine the target second coordinate of the photoresist in the horizontal direction as the difference between the original first coordinate and the preset width of the photoresist and the first width.
[0083] In some embodiments, if the preset first coordinate is X0 and the preset width of the photoresist is L0, then the target second coordinate is X0+L0-L1.
[0084] In this embodiment of the application, a schematic diagram of the target position of the photoresist is shown, as follows: Figure 8 As shown.
[0085] In some embodiments, after step S104 is performed, the method may further include:
[0086] The photoresist is coated on the surface of the structure at the target location; ions are injected into the surface of the structure at the ion implantation angle to form a pattern on the surface of the structure.
