FR three-hole mask

example sentence

1 Make some holes in the mask for your eyes.

Tear two holes in the mask so that your eyes can look out.

2. A 2D photorefractive photonic lattice with single-line defects with a width of 40μ m was successfully fabricated in LiNbO _ 3: Fe crystal by using a cylindrical lens to shape the sliced beam. The effects of irradiation time, light intensity ratio, mask hole spacing and probe light frequency on the optical properties of defect photonic lattice are analyzed and discussed. Based on this, we found the best experimental conditions.

Two-dimensional defect photonic lattice with single-line defect width of 40μm was successfully prepared in LiNbO3:Fe crystal by sheet light method. The effects of induction time, writing light intensity ratio, mask hole spacing and probe light frequency on the optical properties of defect lattice are analyzed and discussed, and the best experimental conditions are found. Through theoretical calculation, the photonic lattice with single-line defects is numerically simulated, and the experiment is consistent with the theory.

3. Using Cl2/ SiCl4 mixture and photoresist as masks, a RIE process for etching vias is developed.

This paper introduces the reactive ion etching process of back hole with Cl2/SiCl4 _ 4 as the reactive gas and positive photoresist as the mask.

4. Phase shift mask for 0.35 micron contact hole

Study on phase shift mask of 0.35μm contact hole pattern

Greenspan secretly looked around, took off the police mask and revealed that "we" had sent (Hank) Paulson to drill several holes in China at the end of 2006.

Greenspan looked around calmly, took off his police mask and admitted that "we" sent (Hank Paulson) to drill several holes before the end of 2006.
