1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

This study investigates a metal-contact etching process that differs from conventional device contact etching by focusing on the film-stack configuration and the associated super-contact etching characteristics. Because metal-contact etching is closely linked to both physical profiles and electrical performance, evaluating a single parameter provides limited insight; thus, the physical profile characteristics of metal-contact etching and 3D-integrated super-contacts were comprehensively examined. In the first-step etch, the target depth in the wafer left region was approximately 2365 Å, and the bottom surface exhibited a desirable rounded profile. Following the removal of liner TEOS and nitride, the stopping margin was evaluated under three conditions: (1) metal-contact etching with a ~22 s target reduction, (2) a CMOS image-sensor baseline incorporating an interlayer-dielectric-reduction scheme, and (3) a high-selectivity condition achieved by increasing the C
