IDM manufacturers refer to the manufacturers from design to research and development all by themselves, with the strongest comprehensive strength, such as intel.
In the chip field, there are three models: IDM, Foundry and Fabless. Foundry refers to the chip foundry, which only produces chips but does not design chips, such as TSMC and SMIC. And Fabless refers to the design of chips, do not produce chips, such as Huawei, Qualcomm, Mediatek, Apple.
However, in the previous year, the domestic mobile phone ODM manufacturer Wentai staged a big acquisition, the acquisition of Anshi Semiconductor, and Anshi is the IDM chip giant in the automotive field, is the world's power semiconductor leader, so Wentai can be said to be the current mainland's most cattle IDM chip manufacturers, they can handle all aspects of the design and manufacture of chips.
IDM (Integrated device manufacturer) refers to Intel, IBM, and Samsung, which have their own fabs, set chip design, manufacturing, packaging, testing, and investing in the five links of the consumer market, and generally have downstream machine production.
