Design-Process-Technology Co-optimization for Manufacturability XIV.
Memory cells and access structures consume a large percentage of area in embedded devices so there is a high return from shrinking the cell area as much as possible. This aggressive scaling leads to very difficult resolution, 2D CD control and proces

Hot spot fixing (HSF) method has been used to fix many hot spots automatically. However, conventional HSF based on a biasing based modification is difficult to fix many hot spots under a low-k1 lithography condition. In this paper we proposed a new H

A practical flare-aware optical proximity correction (OPC) tool for full-chip level has been developed for upcoming extreme ultraviolet lithography (EUVL). The conventional flare-aware OPC method for EUVL is unsuitable for practical use because it re

Based on an acceptable wafer critical dimension (CD) variation that takes device performance into consideration, we presented a methodology for deriving an acceptable mask defect size using defect printability [1]-[3]. The defect printability is meas

Computational spacer patterning technology (SPT) has been developed for the first time to address the challenges concerning hotspots and mask specifications in SPT. A simulation combined with a lithography, etching and deposition model shows the stro

We obtained the acceptable mask defect size for both opaque and clear defects in the spacer patterning process using the fail-bit-map analysis and a mask with programmed defects. The spacer patterning process consists of the development of photoresis

We have studied both the mask CD specification and the mask defect specification for spacer patterning technology (SPT). SPT has the possibility of extending optical lithography to below 40nm half-pitch devices. Since SPT necessitates somewhat more c

Flow of fixing of hot spot induced by optical variation among exposure tools is discussed for quick ramp-up of high volume products. To achieve robust pattern formation for optical variation, following hot spot detection and fixing approaches are int
