The ASML DUV stepper is a 248nm line stepper for imaging dense features down to below 200nm and isolated line structures down to below 150nm. The system is a variable NA system and has a field image size of 21 x 21mm for 0.63 NA and a field size of 22mm x 27mm for 0.4 to 0.57NA. Overlay accuracy is better than 30nm. The system is configured for 4” wafers and pieces down to 14mm in size can be exposed using a 4” wafer as a carrier.

About

The ASML 5500 stepper is a 248nm DUV stepper for imaging dense features down to below 200nm and isolated line structures down to below 150nm. Overlay accuracy is better than 30nm.

The system is configured for 4” wafers and, with staff support, mounted pieces down to 14mm in size can be exposed using a 4” wafer as a carrier. The system is designed for high throughput, so shooting multiple 4" wafers is extremely fast. Additionally, exposure jobs are highly programmable, allowing for very flexible exposures of multiple aligned patterns from multiple masks in a single session, allowing for process optimization of large vs. small features in a single lithography.

The full field useable exposure area is limited to the intersection of a 31mm diameter circle and a rectangle of dimensions 22mm x 27mm. See the Mask Making Guidelines page for more info on exposure field sizes and how to order your mask plates.

Resists Used (see PhotoLith. Recipes for full process info):

  • UV210-0.3 - Positive: 300nm nominal thickness
  • UV6-0.8 - Positive: 800nm nominal thickness
  • UV26-2.5 - Positive: 2.5um nominal thickness
  • UVN2300-0.5 - Negative: 500nm nominal thickness
  • DUV42P-6/DS-K101 - Bottom Anti-Reflective Coatings “BARC”

Process Information

  • Process Recipes Page > "Stepper 3" - Established recipes and corresponding linewidths, photoresists etc.
  • Sample size: 100 mm wafers with SEMI std. major flat
    • Piece-parts process is possible but difficult - contact staff for info
  • Alignment Accuracy: < 50 nm
  • Minimum Feature Size: ≤150 nm isolated lines, ≤200 nm dense patterns
  • Maximum Wafer Bow: approx. 100 µm. (4-inch diam.)
