Abstract

We discuss three models describing the carrier densities in highly doped silicon, which have been used for process and device simulation. We calculate nie for each of the models for various doping concentrations within temperature ranges interesting for the device and process simulation. We try to explain the behaviour of nie for high compensation and compare our calculated results to measured values of nie. We offer simple formulae for the calculated nie and show how far the relations between the carrier densities and the Fermi levels can be described by the simple formulae of Boltzmann statistics when we use a doping dependent effective intrinsic number.

Abstract

A general algorithm for analysis of semiconductors with arbitrary models for heavy doping phenomena is presented. Different models, theoretical as well as empirical, were applied, and minority carrier concentration in the uncompensated n‐type silicon was analyzed. Recalculated into the term of apparent BGN, the results were compared with experimental data. Further analysis of apparent BGN indicated the weakness of empirical formulae for apparent BGN. Assumption of total ionization of impurities considered in the analysis is discussed and justified.

Abstract

This paper describes a new two‐dimensional process simulation program MUSIC (MUltigrid Simulator for IC fabrication processes) which is prospective for the efficient IC process simulations due to its capability to eliminate strong bottlenecks present in the existing two‐dimensional process simulation programs. Multistep processes, including ion implantation, diffusion and oxidation, can be simulated, giving the doping profile. Robust and efficient adaptive multigrid numerical techniques for the simulation of coupled multiparticle diffusion processes are used. The capabilities of program MUSIC are illustrated by the results of the process flow simulation of a typical NMOS and bipolar transistors fabricated in BiCMOS technology.

Abstract

The coupled set of non‐linear 2D diffusion equations for donor and acceptor type impurities with initial and appropriated boundary conditions is solved by an implicit locally‐one dimensional finite difference method. Numerical experiments have been made to achieve a reasonable trade‐off between the desired accuracy and the CPU time. The algorithm was implemented to the process module of the 2‐D integrated process and device modeling system IMPEDANCE 2.0.

Abstract

Purpose

This study intends to find the industries that have leveraged Robotic Process Automation (RPA) technology and elucidate the extent of the adoption of RPA in various industry domains with benefits. The identification of tasks eligible for RPA itself is a challenge. Therefore, the study further brings out the challenges faced in various industry verticals and postulates the future direction of research and applications in RPA.

Design/methodology/approach

The study focuses on articles from popular databases such as SCOPUS, Web of Science and Google scholar. PRISMA methodology is used for systematic literature review and 113 papers are shortlisted for study. Three questions are framed to carry out the review and set the research direction.

Findings

It is evident from this study that RPA has been widely used in banking and related areas with moderate use in healthcare and manufacturing leading to operational efficiency and productivity. However, there are a lot more opportunities in other domains that need to be taped by leveraging technology advancements and a research agenda has been devised by postulating future directions.

Originality/value

The study brings out a new comprehensive perspective as regards RPA implementation across domains. There is no promising study found that gathers three-dimensional aspects of the meta-themes applications, benefits and challenges. The study summarizes the research agenda and projects the industry domains that have not yet explored, the benefits of RPA. This will be a good reference article for those who develop RPA techniques and organizations that have plans to go for RPA.

Abstract

Purpose

To determine where, when, how, and wherefore European social theory hit upon the formula of “the True, the Good, and the Beautiful,” and how its structural position as a skeleton for the theory of action has changed.

Methodology/approach

Genealogy, library research, and unusually good fortune were used to trace back the origin of what was to become a ubiquitous phrase, and to reconstruct the debates that made deploying the term seem important to writers.

Findings

The triad, although sometimes used accidentally in the renaissance, assumed a key structural place with a rise of Neo-Platonism in the eighteenth century associated with a new interest in providing a serious analysis of taste. It was a focus on taste that allowed the Beautiful to assume a position that was structurally homologous to those of the True and the Good, long understood as potential parallels. Although the first efforts were ones that attempted to emphasize the unification of the human spirit, the triad, once formulated, was attractive to faculties theorists more interested in decomposing the soul. They seized upon the triad as corresponding to an emerging sense of a tripartition of the soul. Finally, the members of the triad became re-understood as values, now as orthogonal dimensions.

Originality/value

This seems to be the first time the story of the development of the triad – one of the most ubiquitous architectonics in social thought – has been told.

Abstract

Purpose

This research focuses on the development and characterization of oil-wetted spun-bonded polypropylene (PP) non-woven filters for improved air intake systems in automobiles. The study aims to enhance engine performance, durability, fuel economy and emission reduction by addressing key aspects such as contaminants filtration efficiency, loading capacity, pressure drop, temperature performance and longevity.

Design/methodology/approach

The research methodology involves the utilization of textile fabrics, particularly oil-wetted spun-bonded PP non-woven filters, renowned for their effective particle collection capability from intake air. Experiments were conducted using a Box–Behnken design with three variables – oil concentration, areal density and dust quantity – each at three different levels to establish correlations with the filter’s dust holding capacity (DHC) and pressure drop.

Findings

The findings indicate that immersing particles in oil-coated medium significantly enhances the filter’s DHC. Notably, castor oil as a coating demonstrates remarkable results, with a 97.53% increase in DHC and a high particulate matter filtration efficiency of 94.12%.

Originality/value

This study contributes to the originality of research by emphasizing the importance of oil density in determining the filter’s DHC and filtration efficiency. Furthermore, it highlights the superiority of castor oil over coconut oil-coated filter media, advancing air intake and/or filter systems for automotive engines.

Abstract

John McGee's 1958 paper, “Predatory Price Cutting: The Standard Oil (NJ) Case,” has had an astonishing influence on both antitrust policy in the United States and economic lore. McGee argued that predatory pricing is irrational and his analysis of the Standard Oil Company Matter, decided in 1911, led him to conclude that the Record in this case does not show that Standard Oil engaged in predatory pricing. This single publication appears to serve as a foundation of the U.S. Supreme Court's position on the issue of predatory pricing, as well as the assertion by many economists that predatory pricing is irrational and rarely occurs.

Numerous arguments have been advanced during the past 25 years that predatory pricing can be a rational strategy. As to McGee's empirical findings, there has been no re-examination of the Record of the Standard Oil case to determine the validity of his finding that the trial “Record” does not support the claim that Standard Oil engaged in predatory pricing.

We examined this Record and have found that the trial Record contains considerable evidence of predatory pricing by Standard Oil. Therefore, the Record does not support McGee's conclusion that Standard Oil did not engage in predatory pricing.

Thus, the decisions of the Supreme Court in recent years, as well as the opinions of many economists, concerning predatory pricing are not consistent with either current theory or the empirical record.

Abstract

Purpose

In this paper the authors aim to examine the forms in which feminist activism is played out at contemporary managerial universities and pose the following question: what notions of feminist activism and feminist theory have to be revisited in order to sustain the target of gender equality and support its move further into the centre and the mainstream of managerial universities?

Design/methodology/approach

Based on action research the authors document a workshop which they organised for different constituencies (administrators, researchers and feminist activists) working towards gender equality at an Austrian university and discuss its results in the context of feminist theory.

Findings

The five voices collected at the workshop show that feminist theories are still the underlying guiding principles for feminist activism towards gender equality at managerial universities. As this is the first time that different generations of feminist activists have been present at managerial universities and are working in a top‐down environment supported by administrators responsible for gender equality, common practices that have been successful to implement gender equality in the past have to be refined and new spaces for collaboration established.

Originality/value

This is the first paper that explores the multiple voices amongst those engaged in the process of transformation towards gender equality at contemporary managerial universities. It shows that an open discussion of complementary and conflicting ways in which the representatives can construct their selves, their strategies and their actions is required in order to start “managing the management” anew – from a higher level than the feminist grassroots activists in the 1980s and 1990s.
