Abstract:
A semiconductor device and method of manufacturing are presented in which features of reduced size are formed using an irradiated mask material. In an embodiment a mask material that has been irradiated with charged ions is utilized to focus a subsequent irradiation process. In another embodiment the mask material is irradiated in order to reshape the mask material and reduce the size of openings formed within the mask material. Through such processes the limits of photolithography may be circumvented and smaller feature sizes may be achieved.
