Quantifying imaging performance bounds of extreme dipole illumination in high NA optical lithography
Publikováno v:
SPIE Proceedings.
We present a framework to analyze the performance of optical imaging in a hyper numerical aperture (NA) immersion lithography scanner. We investigate the method to quantify imaging performance by computing upperand lower-bounds on the threshold norma

We present a metrology target design (MTD) framework based on co-optimizing lithography and metrology performance. The overlay metrology performance is strongly related to the target design and optimizing the target under different process variations

We present a cost-effective focus monitoring technique based on the illumination and the target co-optimization. An advanced immersion scanner can provide the freeform illumination that enables the use of any kind of custom source shape by using a pr

We present a novel metrology target design framework using the scanner exit pupil wavefront analysis together with Zernike sensitivity analysis (ZSA) based on the Monte-Carlo technique. The proposed method enables the design of robust metrology targe

Feedback control of overlay errors to the scanner is a well-established technique in semiconductor manufacturing [1]. Typically, overlay errors are measured, and then modeled by least-squares fitting to an overlay model. Overlay models are typically

Picosecond photothermal displacement experiments were performed to resolve the rise time of the actual surface expansion of laser‐illuminated metals. A rise time of ∼100 ps was resolved for Ni, in agreement with the predictions of a hydrodynamic

Spectroscopic CD (SCD) technology provides high precision shape information with excellent correlation to established critical dimension metrology. Poly-gate wafers from over 20 lots produced in a high-volume manufacturing fab were measured and analy

The accelerating trend to smaller linewidths and low-kl lithography makes metrology and process control more challenging with each succeeding technology generation. Optical CD metrology based on spectroscopic ellipsometry provides higher precision, i

Fundamentally, advanced process control enables accelerated design-rule reduction, but simple microeconomic models that directly link the effects of advanced process control to profitability are rare or non-existent. In this work, we derive these lin

Smaller device dimensions and tighter process control windows have created a need for CD metrology tools having higher levels of precision and accuracy. Furthermore, the need to detect and measure changes in feature profiles is becoming critical to i
