“…Therefore, a good number of studies have focused on reducing the operating voltage [15][16][17][18]. In addition to the above two aspects, reliability issue of OTFTs is also a concern and has been investigated by several research groups [19][20][21]. OTFTs should have good stability, longer life-time and should operate reliably when operated under different environmental conditions.…”

Organic thin film transistors (OTFTs) are key building blocks for flexible, low cost electronics systems. They provide a viable alternative for silicon-based electronics with added advantages of low cost and flexibility. However, few issues like high-operating voltage, low-switching speed, high-leakage current and reliability are still a challenge. The overall performance of an OTFT depends on organic semiconductors and gate dielectric interface. In this paper, we review the current status and trends in the choice of dielectric layer for OTFTs. As a starting point, the performance parameters of an OTFT and their dependence on the dielectric layer are briefly discussed. A variety of dielectric materials which includes high-k inorganic, organic, surface coated inorganics and nanocomposites are also presented. The advantages and drawbacks of each of these materials are discussed in detail. We reviewed the latest developments in the dielectric materials especially, self-assembled monolayers (SAMs), hybrid bilayers and nanocomposites. SAM-based OTFTs offer several advantages but shift in the threshold voltage remains a concern. Nanocomposites are a latest addition to the dielectric materials, which offer advantages like solution processing and improved dielectric constant but have a rough surface. A hybrid bilayer that incorporates the inorganic dielectric as a base layer and a thin polymer layer over it to improve the surface properties offers several desirable characteristics over the other choices. Hence, we propose that hybrid bilayer gate dielectrics shall play a pivotal role in improving the OTFT performance.

“…In the present time, one can find an increase in the density of elements of integrated circuits due to increase in the density of their dimensions and optimization of technological processes to improve properties of these circuits (Wrachien et al , 2013; Kargarrazi et al , 2016; Pal et al , 2015; Choi and Park, 2011; Senthilpari et al , 2009; Subramaniam et al , 2013). One can also find increase in the speed of these elements.…”

Purpose The purpose of this paper is to analyze the redistribution of dopant and radiation defects to determine conditions which correspond to decreasing of elements in the considered inverter and at the same time to increase their density. Design/methodology/approach In this paper, the authors introduce an approach to increase integration rate of elements in a three-level inverter. The approach is based on decrease in the dimension of elements of the inverter (diodes and bipolar transistors) due to manufacturing of these elements by diffusion or ion implantation in a heterostructure with specific configuration and optimization of annealing of dopant and radiation defects. Findings The authors formulate recommendations to increase density of elements of the inverter with a decrease in their dimensions. Practical implications Optimization of manufacturing of integrated circuits and their elements. Originality/value The results of this paper are based on original analysis of transport of dopant with account transport and interaction of radiation defects.
