Fabless Semiconductor Model

Cirrus Logic conducts its product research and design in-house, along with validation, qualification, and failure analysis. As a fabless semiconductor company, we outsource the semiconductor manufacturing process, which includes fabrication, assembly, testing and distribution, to premier suppliers across the globe.

The supply chain management team is responsible for overseeing all aspects of this process, and our engineering operations teams manage process and package development, test program development and product quality, in accordance with our ISO 9001 certified quality management system. This manufacturing strategy allows us to concentrate on our design strengths and minimize fixed costs and capital expenditures. The relationships we build with our tier-one suppliers are critical for maintaining access to leading-edge technologies which enable the company’s ongoing innovation in low-power, high-performance mixed-signal products.

All foundries, assembly, and test sites that we work must maintain ISO 14001 certificates and adhere to the Cirrus Logic Supplier Code of Conduct.

Our “Fabless” Production Model — Five Distinct Production Stages

Research

Cirrus Logic in-house engineering design teams to explore new semiconductor architectures and materials to spur innovation in integrated circuits (ICs). R&D efforts are concentrated on the design and development of new products for each of the company’s principal markets, utilizing a combination of market research and customer feedback to inform our innovation process. We also work to develop certain advanced process technologies, as well as other emerging product opportunities.

Design and Validation

Cirrus Logic engineers begin IC design in collaboration with our silicon layout designers through a series of stages to convert the product specifications into the physical layout and electrical components necessary to meet those requirements. Our team verifies each stage of the design to ensure that when the IC actually is built it will meet both our exacting specifications and our high-quality standards.

Fabrication

Once product design is initiated, Cirrus Logic selects a foundry that can meet the specific product performance, production volume demand and quality requirements. Cirrus Logic maintains relationships with several foundries to provide a spectrum of potential solutions for our products. The foundries produce products to our specifications using pure silicon wafers and raw materials using highly sophisticated equipment. We work closely with these foundries to ensure the products are delivered on-time, on-spec and to our quality specifications.

Assembly and Test

Cirrus Logic devices exit the foundry in wafer form and ship directly to our highly specialized vendors for final assembly and test. During the die packaging process, wafers are transformed into components that are capable of interfacing with the customer’s end application. In addition to assembly, our packaging providers test each device to ensure functionality is within specification. Cirrus Logic packaging, test and quality engineers and supply chain management organization are engaged throughout the assembly and test process to ensure products are delivered on time and adhere to our quality standards.
