What is semiconductor assembly and test?
OSAT (Outsourced semiconductor assembly and test) are the companies that offer third-party IC-packaging and test services. These companies provide packaging to silicon devices that are made by foundries and test devices prior to shipping to the market.
What is assembly in semiconductor?
assembly – the process of putting a semiconductor device or integrated circuit in a package of one form or another; it usually consists of a series of packaging steps that include: die preparation, die attach, wirebonding, encapsulation or sealing, deflash, lead trimming/forming, and lead finish.
Which of these are assembly and test providers?
Some of the major players involved in the Global Outsourced Semiconductor Assembly And Test (OSAT) Market are ASE Group, Amkor, JCET, Siliconware Precision Industries Co., Ltd., KYEC, Hana Micron, Signetics, Unisem Group, Walton Advanced Engineering, Powertech Technology Inc.
What is semiconductor packaging and testing?
In other words, semiconductor packaging serves a variety of purposes: ensuring the inter-terminal connection, supplying electricity, and providing heat resistance and protection for the IC. The packaging also ensures protection from external factors, including humidity, chemicals, impact and vibration.
What is wafer assembly?
The first, wafer fabrication, is the extremely sophisticated and intricate process of manufacturing the silicon chip. The second, assembly, is the highly precise and automated process of pack- aging the die. Those two phases are commonly known as “Front-End” and “Back-End”.
Who are the OSATs?

What is fabrication semiconductor?
Semiconductor device fabrication is the process used to manufacture semiconductor devices, typically the metal–oxide–semiconductor (MOS) devices used in the integrated circuit (IC) chips such as modern computer processors, microcontrollers, and memory chips such as NAND flash and DRAM that are present in everyday …
What is IDM semiconductor?
Description. A semiconductor company that designs, manufactures, and sells integrated circuits (ICs) is an integrated device manufacturer (IDM). A traditional IDM owns its own branded chips and does the design in-house and has a fabrication plant where it manufactures its ICs.
What is semiconductor testing?
Semiconductor test equipment (IC tester), or automated test equipment (ATE), is a system for giving electrical signals to a semiconductor device to compare output signals against expected values for the purpose of testing if the device works as specified in its design specifications.
How is semiconductor manufactured?
In the manufacturing process of IC, electronic circuits with components such as transistors are formed on the surface of a silicon crystal wafer. A thin film layer that will form the wiring, transistors and other components is deposited on the wafer (deposition). The thin film is coated with photoresist.
What is a node in semiconductor?
The technology node (also process node, process technology or simply node) refers to a specific semiconductor manufacturing process and its design rules. Different nodes often imply different circuit generations and architectures.
What is outsourced semiconductor assembly and test?
Outsourced semiconductor assembly and test (manufacturing) vendors provide third-party IC-packaging and test services. The OSATs are merchant vendors.
What are the opportunities in the semiconductor assembly and testing services market?
Increasing demand for mobility and connectivity in consumer electronic products and increasing use of safety systems in automobile industry, which is a major opportunities for the semiconductor assembly and testing services market Which region is expected to be at forefront in the semiconductor assembly and testing services market?
What is the role of Osat in the semiconductor industry?
OSAT providers have an extremely important role in the semiconductor industry, now more than ever, due to the fact that they are the bridge that covers the divide between the semiconductor foundries and consumers. OSAT vendors provide testing services such as: wafer test and final test.
How has Asia-Pacific impacted the semiconductor manufacturing industry?
Most semiconductor manufacturing industries have been impacted by the fact that the Asia-Pacific region has become a world production center over the past twenty to thirty years.
