Embodiment
[0018] In this example, the substrates with photoresist are manufactured using the existing technology, and the prepared substrates with photoresist are respectively immersed in the stripping solution of the test group. For rinsing treatment, the components and dosage of each test group are shown in Table 2. The peeling results were carried out with reference to the conventional metal corrosion resistance and peelability evaluation standards. The metal corrosion resistance and peelability evaluation standards are shown in Table 1, and the peeling results are shown in Table 2. In this example, the balance in each test group is deionized water.
