TECHNICAL FIELD

[0002] With the development of chip preparation technology and the development of 5G technology, the quality requirements for prepared storage chips are gradually increasing, for example, high preparation requirements for the thermal stability and electrical signal stability of storage chips. However, the existing technology still cannot meet the preparation quality requirements of storage chips.
[0003] At present, some schemes use scene modeling and simulation simulation to simulate and test various parameters of the storage chip to be put into use. The scene modeling refers to the process of abstracting the running logic of various parameters of the storage chip in operation into a mathematical model. The simulation simulation refers to the process of simulating the running logic of various parameters of the storage chip in operation. Both of them are processes of describing the running logic of the storage chip. However, neither the former nor the latter is modeled in the prior art. The storage chip is modeled as a whole, and the internal parts of the storage chip are not modeled. For example, when the storage chip is installed on a certain A device, the prior art models the electrical signal, temperature and other data of the storage chip as a whole on the A device, and there is no scheme that can model the internal parts of a single storage chip. In addition, the storage chip is the result of circuit integration, which inevitably contains a large number of electronic devices. If these large numbers of electronic devices are modeled one by one, the modeling workload will be huge.

[0144] Compared to the problems described in the background art, this embodiment of the invention disassembles the memory chip into multiple subdivided components, thereby enabling detailed modeling of these subdivided components. Furthermore, this embodiment identifies the equivalent circuit diagram of the internal circuit diagram to simplify complex circuit diagrams with numerous components, reducing the workload of subsequent data modeling based on the circuit diagram. Further, this embodiment constructs an equivalent circuit model of the equivalent circuit diagram to abstract the internal circuit logic of the memory chip into a model form. Further, this embodiment performs model differentiation on the equivalent circuit model to observe the changes in voltage and current signals over time and the relationship between voltage and current signals. Further, this embodiment... The internal circuit diagram is used to identify the heating circuit diagram of the heat-generating component, which is then converted into an equivalent circuit diagram containing only the heat-generating component. Further, this embodiment calculates the deformation parameters of the deformable component to calculate the parameters of each deformable component, performing structural scene modeling on each component's data. Further, this embodiment constructs an initial deformation model between the temperature parameters and the deformation parameters of the deformable component to generate a regression model between the temperature parameters and the deformation parameters, thereby determining the relationship between the deformation parameters and temperature changes. Further, this embodiment uses a preset particle swarm optimization algorithm to adjust the accuracy of the initial deformation model, obtaining an adjusted deformation model, which is then used to solve for the unknown regression coefficients in the initial deformation model using the particle swarm optimization algorithm. Therefore, the scene modeling method proposed in this invention for memory chip fabrication can refine scene modeling while reducing the workload of scene modeling.
