As early as 2012, Huawei planned to research and develop its own operating system Hongmeng, and officially released Hongmeng operating system in 2019. As we all know, most of Huawei's previous cell phone operating systems used Android and windows systems, and with Hongmeng is also equal to self-sustaining. Then what is Hongmeng?
Hongmeng will create a full-scene distributed cloud presence, mainly for the Internet of Things. Not only for devices such as phones, tablets, computers and cars, but for connecting all devices in tandem. Hongmeng system has been applied to Huawei cloud scene, Huawei wearable devices, and in the future is to be applied to multi-scene terminal equipment.
Photolithography and chips
As we all know, chips and photolithography are inextricably linked, and the chip is the brain of the phone, controlling the operation of the phone. And the lithography is the main production equipment for the chip, the world's only Dutch ASML company and Japan's Canon, Nikon production of lithography, and the three together can only produce 300 units a year.
At the same time, the Dutch technology is the most advanced and is not openly disclosed to the public, China's Semiconductor Manufacturing International (SMIC) has spent 700 million yuan to buy a photolithography machine in ASML. And no matter at home or abroad there are countless technology companies in its purchase, visible its importance. Huawei currently does not have this technology, so rather than being chip necked, it is said to be photolithography necked.
Photolithography how to make a chip
The cell phone chip is a very small integrated circuit template, and the template on the wafer plays a role in the beginning and end, first of all, it is necessary to carve out the body of the wafer in line with the production standards. Ultraviolet light source is one of the core components of the photolithography exposure system, the need for ultraviolet light source to remove a layer of isolation film on the wafer. Then put into the professional system of acid and alkaline water, and constantly bubbling to form the circuit.
And the common light source is divided into, ultraviolet i line, deep ultraviolet excimer laser, excimer laser, extreme ultraviolet light, each of the amount of light has a specific nanometer value to measure, and the size of the amount of light is critical to etching for the accuracy of the accuracy of the higher. In accordance with the construction process according to the size of the appropriate wavelength selection adjustment to control the light source can be.
Hongmeng makes photolithography more dependent?
Huawei's Hongmeng operating system, just transition under the temporary avoidance of bottlenecks. Replaced by the arrival of the cloud scene application, but as long as the smart device hardware will always use the chip connection, with the arrival of 5G technology, life scenarios are also more and more specific, and more stringent on all aspects of the smart device. Hongmeng just gave us a transition period, really need to still firmly grasp the lithography technology, so Huawei still has a longer way to go.
