What are fabless semiconductors and why are they important?




Fabless semiconductors are ICs that are designed by a company that does not own or operate a fabrication facility (also known as a fab). Instead, the company outsources the fabrication of its ICs to a third-party foundry that specializes in manufacturing ICs. This way, the company can focus on its core competencies in design, innovation, marketing, and customer service, while reducing its capital expenditure, operational costs, and risks associated with owning a fab.


Fabless semiconductors are important because they enable faster, cheaper, and more flexible development of ICs for various applications such as computing, communication, consumer electronics, automotive, industrial, medical, aerospace, defense, etc. Fabless semiconductors also foster more competition and collaboration among different players in the semiconductor industry, such as designers, foundries, suppliers, distributors, customers, etc. According to a report by IC Insights, fabless semiconductor companies accounted for 32% of the global IC sales in 2020, up from 18% in 2010, and are expected to grow further in the future.


How are fabless semiconductors implemented?




Fabless semiconductor implementation involves a series of steps that transform a design idea into a physical product. The main steps are design specification and verification, logic synthesis and optimization, physical design and layout, fabrication and testing. Each step requires different skills, tools, and methods to ensure the quality and performance of the final product. Let's take a closer look at each step.


Design specification and verification




The first step in fabless semiconductor implementation is to define and verify the functional and performance requirements of the chip. This involves capturing the design intent using a high-level description language (HDL) such as Verilog or VHDL, or a graphical user interface (GUI) such as Matlab or Simulink. The design specification describes what the chip does, how it interacts with other components, and what are its inputs and outputs. The design verification involves checking the correctness and completeness of the design specification using various techniques such as simulation, formal methods, emulation, prototyping, etc. The design verification ensures that the design meets the customer's expectations and complies with the industry standards and regulations.


Logic synthesis and optimization




The second step in fabless semiconductor implementation is to translate the design specification into a logic circuit that can be implemented on a chip. This involves using a logic synthesis tool that converts the HDL or GUI description into a netlist of gates, flip-flops, registers, multiplexers, etc. The logic synthesis tool also performs optimization of the logic circuit for speed, area, and power consumption, by applying various techniques such as logic minimization, technology mapping, retiming, etc. The logic synthesis and optimization ensures that the logic circuit meets the performance goals and constraints of the chip.


Physical design and layout




The third step in fabless semiconductor implementation is to map the logic circuit onto a physical layout that can be fabricated on a chip. This involves using a physical design tool that performs placement, routing, and timing analysis of the logic circuit on a given chip area. The placement assigns each gate or cell to a specific location on the chip. The routing connects each gate or cell with wires or interconnects. The timing analysis verifies that the signal propagation delays meet the timing requirements of the chip. The physical design tool also performs optimization of the physical layout for speed, area, power consumption, noise, reliability, etc., by applying various techniques such as floorplanning, partitioning, clock tree synthesis, wire sizing, etc. The physical design and layout ensures that the physical layout meets the fabrication specifications and constraints of the foundry.


Fabrication and testing




The fourth step in fabless semiconductor implementation is to outsource the fabrication of the chip to a foundry that specializes in manufacturing ICs. This involves sending the physical layout file to the foundry along with some information such as process technology, mask layers, wafer size, etc. The foundry then uses various processes such as lithography, etching, doping, metallization, etc., to create millions of identical copies of the chip on a silicon wafer. The fabrication process can take several weeks or months depending on the complexity and volume of the chip. After fabrication, the foundry also performs testing of the chip for functionality and quality using various techniques such as electrical testing, optical inspection, defect analysis, etc. The fabrication and testing ensures that the chip meets the functional and quality standards of the customer.


What are some challenges and opportunities for fabless semiconductor implementation?




Fabless semiconductor implementation is not without its challenges and opportunities. As technology advances and market demands change, fabless semiconductor companies face various issues and trends that affect their design process and business model. Some of these are:


Technology scaling and innovation




One of the main challenges for fabless semiconductor implementation is to cope with the increasing complexity and cost of chip design as technology scales down. As ICs become smaller, faster, denser, and more power-efficient, they also become more difficult to design, verify, optimize, layout, fabricate, test, etc. Moreover, as ICs become more integrated with other components such as sensors, actuators, memories, processors, etc., they also require more innovation and creativity to achieve new functionalities and performance levels. Fabless semiconductor companies need to invest more in research and development (R&D) to keep up with these technological challenges and opportunities.


Design automation and verification




Another challenge for fabless semiconductor implementation is to leverage advanced tools and methods to automate the design process. As chip design becomes more complex and costly, fabless semiconductor companies need to rely more on design automation and verification tools that can help them reduce the design time, cost, and errors, and improve the design quality and performance. Design automation tools can perform tasks such as logic synthesis, optimization, physical design, layout, etc., automatically or semi-automatically. Design verification tools can check the correctness and completeness of the design specification, logic circuit, physical layout, etc., using techniques such as simulation, formal methods, emulation, prototyping, etc. Fabless semiconductor companies need to adopt and integrate these tools into their design flow to enhance their productivity and competitiveness.


Intellectual property and security




A third challenge for fabless semiconductor implementation is to protect and manage the intellectual property rights and security of the chip design. As chip design becomes more innovative and valuable, it also becomes more vulnerable to theft, piracy, counterfeiting, tampering, etc. Fabless semiconductor companies need to safeguard their intellectual property rights and security by using various measures such as patents, trademarks, licenses, contracts, encryption, authentication, obfuscation, watermarking, etc. Fabless semiconductor companies also need to collaborate with their foundries, suppliers, distributors, customers, etc., to ensure the confidentiality and integrity of their chip design throughout the supply chain.


Market competition and collaboration




A fourth challenge for fabless semiconductor implementation is to compete and collaborate with other fabless semiconductor companies in the global market. As chip design becomes more diverse and dynamic, it also creates more opportunities and threats for fabless semiconductor companies. Fabless semiconductor companies need to compete with each other for market share, customer loyalty, innovation leadership, etc., by offering better products, services, prices, quality, etc. Fabless semiconductor companies also need to collaborate with each other for mutual benefit, such as sharing resources, knowledge, technology, etc., or forming alliances, partnerships, consortia, etc. Fabless semiconductor companies need to balance their competitive and collaborative strategies to achieve their business goals and objectives.
