Solution Overview
Problem
Existing semiconductor components face challenges in optimizing the use of injection layers for charge carrier injection, as they often extend beyond necessary areas, affecting adjacent components and requiring complex structuring, which can lead to undesirable doping effects and reduced functionality.
Innovation Solution
The solution involves forming organic semiconductor components with shared electrode layers and injection layers containing p-type and n-type electrical dopants, allowing for differential doping affinities between areas, reducing lateral conductivity and avoiding crosstalk, while maintaining functionality across adjacent components.

1Reliability
If the injection layer is formed over a larger area than necessary for charge carrier injection optimization, then the charge carrier injection is improved, but the injection layer affects adjacent components and causes undesirable doping effects
Solution Approach 1:
The injection layer is divided into multiple segments with different structures or compositions. Specifically, the injection layer comprises a first injection layer portion and a second injection layer portion, where the first portion has a first structure or composition optimized for charge carrier injection, and the second portion has a second structure or composition that minimizes undesirable doping effects on adjacent components.
Solution Approach 2:
Different regions of the injection layer are assigned different properties to fulfill different functions. The first injection layer portion is designed with properties optimized for charge carrier injection, while the second injection layer portion is designed with properties that reduce harmful doping effects on adjacent components, allowing each region to have the appropriate quality for its specific function.
2Object-affected harmful factors
If the injection layer is structured to avoid affecting adjacent components, then the harmful effects on adjacent components are reduced, but the production process becomes more complex
Solution Approach 1:
The first injection layer portion and the second injection layer portion are combined into a single integrated injection layer structure. This merging allows the different functional regions to be produced together in one process sequence, reducing the overall production complexity compared to producing separate injection layers for each component.
Solution Approach 2:
The injection layer is designed to serve multiple functions simultaneously through its different portions. The first portion provides optimized charge carrier injection, while the second portion provides protection against undesirable doping effects on adjacent components, allowing a single injection layer structure to fulfill multiple roles.
3Reliability
If the injection layer is formed in a structured configuration, then the charge carrier injection is optimized in specific areas, but the production process requires more structuring work
Solution Approach 1:
The first injection layer portion is formed first as a preliminary step, providing the optimized charge carrier injection structure. Subsequently, the second injection layer portion is formed to provide the protective function. This preliminary action approach allows each layer to be optimized for its specific function while maintaining a relatively simple production process.

This approach simplifies the production process, reduces structuring requirements, and enhances the injection of charge carriers by creating areas with specific doping affinities, thereby improving the performance of semiconductor components, especially in compact geometries, by minimizing unintended doping effects.
Implementation Method 1
an injection layer which consists of molecular doping materials, charge carriers can be injected more effectively into the organic semiconductor layer adjacent to the injection layer
Implementation Method 2
an additive layer. Upon coming into contact with the molecular doping material, the material of the additive layer alters the doping affinity thereof in respect of the organic material of the semiconductor layer
