To put it briefly (my personal understanding, please forgive me if I am wrong):

The semiconductor industry can be broadly divided into upstream, middle and downstream

The upstream is mainly : design house (design company), FAB (wafer manufacturing plant), test house (test house)

The midstream mainly includes: assembly house (packaging factory), Subcon (foundry)

< p>The downstream mainly includes: SMT (SMT factory), Plant (end consumer goods assembly factory)

Of course, corresponding to different links, they also need their own supplier chains.

FAB (wafer manufacturing plant),

Wafer is commonly known as wafer, wafer, chip

It can be processed according to the size (wafer diameter) is divided into: 4 inches, 5 inches, 6 inches, 8 inches, 12 inches

The actual metric length respectively corresponds to approximately: (25.4*number of inches)mm, which is simply:

4-inch is about 101.6mm, and so on for others

I have never heard of the 10-inch you mentioned

OEM production, also known as fixed-point production Production, commonly known as OEM (production), basically means that brand producers do not directly produce products, but use the key core technologies they have mastered to design and develop new products, control sales channels, and order specific processing tasks through contracts. Entrust other manufacturers of similar products to produce. Afterwards, the ordered products will be bought out at a low price and directly labeled with their own brand trademarks. This cooperation method of entrusting others to produce is referred to as OEM. The manufacturer that undertakes the processing task is called an OEM manufacturer, and the products it produces are called OEM products.

Your company falls into this category.

ODM means that after a manufacturer designs a certain product, in some cases it may be favored by other companies and require the latter's brand name for production, or slightly modify the design. to produce. This allows other manufacturers to reduce their own development time. Manufacturers that undertake design and manufacturing business are called ODM manufacturers, and the products they produce are ODM products.

To put it bluntly, the core difference between OEM and OEM lies in who owns the intellectual property rights of the product. If the client owns the intellectual property rights of the product, it is the OEM, which is also commonly known as "OEM" ; And if it is the overall design carried out by the manufacturer, it is ODM, commonly known as "OEM".
