Negative tone photoresist for euv lithography |
abstract |
A negative tone photoresist and a method for developing the negative tone photoresist are disclosed. For example, a negative tone photoresist includes a solvent, a dissolution inhibitor, and a polymer. The polymer contains hydroxy groups. The polymer may be greater than 40% by weight of the total weight of the negative tone photoresist. |
