<< Definitely not. Better masks facilitate smaller feature sizes which require CYMI's lasers. i.e. The DUV laser light is shone through the mask onto the wafer to form the circuit pattern. Both masks and lasers (in photolithography tools) are required to make chips with small feature sizes.>> Yes, but doesn't this capability tend to delay the necessity of purchasing of new lasers? G.

Masks eliminate the need for Cymer's DUV lasers? Definitely not. Better masks facilitate smaller feature sizes which require CYMI's lasers. i.e. The DUV laser light is shone through the mask onto the wafer to form the circuit pattern. Both masks and lasers (in photolithography tools) are required to make chips with small feature sizes. Sorry- The original article made it sound like some improvement in the masks ALONE made it possible to get smaller. -Thanks for your response -Neal EDIT- I assume DUV is shorter wavelength, that's why it's needed for smaller and smaller features. Masks are just the template this smaller light is shone through..... -Neal
