Chemical composition for tri-layer removal |
| abstract |
The method includes forming three layers. The third layer is the lower layer; An intermediate layer above the lower layer; Includes an upper layer above the middle layer. The top layer includes a photoresist. The method includes removing the top layer; And removing the intermediate layer using a chemical solution. The chemical solution does not contain potassium hydroxide (KOH) and contains at least one of quaternary ammonium hydroxide and quaternary ammonium fluoride. |
