Double Exposure for Mainstream IC Production

Source: Semiconductor International

Attractive option for extending 193nm lithography

Companies looking to double exposure as mainstream

Had been used only on most critical layers

Timing window may be realized sooner; Less costly than implementing new technologies

Compared to EUV, immersion

Double exposure increases metrology requirements

Requires 2x overlay improvement

Requires improved CD control

Double Exposure and Metrology

Primary path for minimum feature resolution:

2002 2004 2006 2008 Scanner 248nm 193nm 193nm Immersion Mask OPC/RET Phase Shift (PSM) Double Exposure

Mask Cost $ $$ $$$$

Overlay budget 15nm 12nm 10nm

Double Exposure is in addition to the previous technology

Increases overlay measurements per layer (up to 2x)

Need to align exposed layer to underlying layer and 2nd expose to 1st exposure

Additional error budget is used in the 2nd exposure

Burden on metrology can more than double in precision and capacity requirements

Triple layer overlayer techniques and targets are emerging to hold capacity flat
