Introduction
In the rapidly evolving semiconductor industry, technological roadmaps serve as essential tools for forecasting trends, guiding research and development, and setting industry standards. One such influential roadmap is the International Technology Roadmap for Semiconductors (ITRS), which has undergone multiple iterations over the years. The ITR2010 was a significant milestone in the roadmap series, addressing crucial aspects of semiconductor scaling, emerging materials, and advanced manufacturing techniques.
This blog will provide an in-depth analysis of ITR2010, comparing it with previous versions, discussing its impact on the semiconductor industry, and answering frequently asked questions (FAQs) related to the roadmap.
What is ITR2010?
The ITR2010, also known as BY-ITR2010, is a component referred to as a "Slot Optical Switch." It consists of two main parts:
• Gallium Arsenide Infrared Emitting Diode (LED): This component emits infrared light. Gallium arsenide is a semiconductor material commonly used for infrared LEDs because it emits light in the infrared spectrum, which is not visible to the human eye.
• Silicon Phototransistor: The emitted infrared light is detected by a silicon phototransistor. Phototransistors are semiconductor devices that can be used to detect light and convert it into an electrical signal.
These components are housed together in a plastic housing. The design of the housing is optimized for several key characteristics:
• Mechanical Resolution: It is designed to ensure precise alignment between the LED and phototransistor, allowing for accurate light detection.
•Coupling Efficiency: The housing is designed to maximize the efficiency of the light transmission between the LED and phototransistor, ensuring reliable operation.
• Ambient Light Isolation: The housing is also designed to block out ambient light, which can interfere with the proper functioning of the device. This is important in applications where the device needs to reliably detect changes in light, such as when an opaque material interrupts the light path.
The "slot" in the housing allows for the interruption of the light signal. When an opaque material, such as paper in a printer, passes through the slot, it blocks the infrared light, causing the output of the phototransistor to switch from an "ON" state to an "OFF" state. This feature is useful in a variety of applications, including printers, scanners, copiers, and any other devices that require the detection of physical objects or interruptions in a light path.
The International Technology Roadmap for Semiconductors (ITRS) 2010 edition (ITR2010) was published to outline the future directions for semiconductor technology. The roadmap analyzed key challenges and solutions for scaling integrated circuits (ICs), incorporating insights from industry leaders, academia, and research institutions.
ITR2010 addressed key topics such as:
• More Moore Scaling – Continued miniaturization of transistors following Moore’s Law.
• More than Moore (MtM) – Heterogeneous integration of functionalities beyond digital scaling.
• Emerging Research Devices (ERD) – Development of novel transistor technologies such as tunnel FETs and spintronics.
• Advanced Manufacturing & Lithography – The introduction of extreme ultraviolet (EUV) lithography.

Applications
• Mouse: It can be used in computer mice to detect the movement of the mouse by interrupting the light beam when the mouse is moved.
• Copier: In photocopiers, the ITR2010 can be used for various purposes, such as detecting paper movement or jamming, or for document feeding.
• Switch Scanner: It can be used in switch scanning applications, where it detects the position of switches or buttons, providing input to electronic devices.
• Floppy Disk Driver: While floppy disk drives are less common today, the ITR2010 may have been used in the past to detect the presence of a floppy disk or to monitor its rotation.
• Non-contact Switching: In non-contact switching applications, the ITR2010 can be used to detect the presence or absence of an object without physical contact, making it suitable for various automation and sensing tasks.
• For Direct Board: This could indicate that it's suitable for direct mounting on a circuit board, making it versatile for integration into various electronic devices and systems.
