Analysis of Focus Errors in Lithography using Phase-Shift Monitors

WebKeywords: Lithography, Focus, Phase-Shift Focus Monitor, 1. INTRODUCTION As the dimensions of devices shrink, the numerical aperture of the lithography scanners increases and the actinic wavelength decreases. This leads to a reduction of the useable depth of focus for lithography printing, as is illustrated in Figure 1. WebLithografie is een grafische techniek die tot de vlakdruk behoort.
