Abstract:
1. A method of making a semiconductor device, the method comprising: forming a middle layer (ML) comprising a photo base generator over a substrate, wherein the ML includes an additive component, the additive component including a photo base generator (PBG); forming a photoresist layer over the middle layer; providing a radiation beam incident the photoresist layer, wherein the radiation beam generates an acid component in the photoresist layer and a base component from the PBG in the middle layer; quenching the generated acid component in the photoresist layer with a first amount of the base component generated; baking the substrate after providing the radiation beam; and after initiating the baking, reacting a second amount of the base component generated in the middle layer wherein the reacting forms covalent bonds between the second amount of the base component in the middle layer and a component of the photoresist layer.
