Stereotype Content Model

Stereotype Content Model

The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence categorization, a person will feel...

Upstream Processing

Upstream Processing

Upstream processing represents a critical phase in biomanufacturing, wherein biological systems such as microorganisms, mammalian cells, or insect cells are cultivated to produce therapeutic proteins, vaccines, enzymes, or other biologically derived products. This phase encompasses all steps from the selection and genetic manipulation of the production organism to the cultivation of cells in bioreactors under tightly controlled environmental conditions.Host Selection and Genetic OptimizationThe...

Imperfections in Crystal Structure: Non-Stoichiometric Defects

Imperfections in Crystal Structure: Non-Stoichiometric Defects

Non-stoichiometric defects refer to a type of defect in the crystal structure of a compound where the ratio of its constituent elements deviates from the ideal stoichiometric ratio. There are two main types of non-stoichiometric defects: metal excess defects and metal deficiency defects.Metal excess defects occur when there is a slight surplus of metal ions than what is required by the stoichiometric ratio of the compound. For example, heating a sodium chloride crystal in sodium vapor results...

Residual Stresses

Residual Stresses

Residual stresses reside in a structure even after removing the original stress inducer. This phenomenon often arises from varied plastic deformations across different parts of a structure. Consider a rod stretched beyond its yield point. It will not regain its original length due to permanent deformation. Even after load removal, the rod does not entirely lose stress because of uneven plastic deformations, resulting in residual stresses. The computation of these stresses in structures is...

Propagation of Uncertainty from Systematic Error

Propagation of Uncertainty from Systematic Error

The atomic mass of an element varies due to the relative ratio of its isotopes. A sample's relative proportion of oxygen isotopes influences its average atomic mass. For instance, if we were to measure the atomic mass of oxygen from a sample, the mass would be a weighted average of the isotopic masses of oxygen in that sample. Since a single sample is not likely to perfectly reflect the true atomic mass of oxygen for all the molecules of oxygen on Earth, the mass we obtain from this particular...

Types of Semiconductors

Types of Semiconductors

Intrinsic semiconductors are highly pure materials with no impurities. At absolute zero, these semiconductors behave as perfect insulators because all the valence electrons are bound, and the conduction band is empty, disallowing electrical conduction. The Fermi level is a concept used to describe the probability of occupancy of energy levels by electrons at thermal equilibrium. In intrinsic semiconductors, the Fermi level is positioned at the midpoint of the energy gap at absolute zero. When...

Summary

This summary is machine-generated.

Manufacturing nanoscale structures is challenging. While 3 nm structures can be fabricated, they lack the reproducibility for practical use, unlike larger 7 nm designs.

Area of Science:

Materials Science
Nanotechnology
Manufacturing Engineering

Background:

Fabrication techniques like deposition, lithography, and etching are used for small structures.
Intrinsic variability in fabricated structures can limit their use in arrays.

Purpose of the Study:

To investigate the manufacturability of nanoscale structures using a top-down approach.
To determine the design rule threshold for transitioning from fabrication to reliable manufacturing.

Main Methods:

Analysis of top-down fabrication processes for structures with 3 nm design rules.
Evaluation of structure reproducibility and yield against pre-ordained specifications.
Comparison of manufacturability at different design rule scales, focusing on 3 nm and 7 nm.

Main Results:

Structures with 3 nm design rules are fabricable but not manufacturable due to insufficient reproducibility.
A satisfactory yield to specification is not achievable for 3 nm structures via top-down methods.
The transition point from manufacturability to intrinsic unmanufacturability occurs around 7 nm design rules.

Conclusions:

Top-down fabrication of 3 nm structures does not meet manufacturing standards for reliable arrays.
Nanoscale manufacturing requires design rules that ensure intrinsic reproducibility, identified as being around 7 nm.
