Silicon carbide is 1 of the most crucial semiconductors due to the fact that it is utilized to produce high-power transistors, which are mounted in electrical vehicles, in various "switch" or photovoltaic devices.
The SiC wafers are much more costly than those made of silicon or sapphire, but much cheaper than GaN, from which power transistors can besides be made.
When optimising the conditions for growth of layers on SiC substrates, they are performed (these layers), tested and then changed the conditions for growth accordingly. To reduce investigation costs, it is worth recovering SiC substrates after polishing the cultured layers. This is not a simple procedure and fundamentally 1 company in the planet offers specified a service. It is simply a French company NovaSiC, which I erstwhile had the pleasance of visiting. Unfortunately, this company is presently in problem due to the fact that China offers SiC substrates cheaper than this polishing service.
Anyone who deals with any technology, akin examples for progressive dominance China can give any amount.
The question is what will happen to our European manufacture erstwhile China produces everything better and cheaper. I just bought a ladder on Temu. It cost 1/3 of what was sold in Poland (maybe besides made in China!).
Europe needs to clean up and start producing equally cheaply. Of course, the production price depends mostly on the scale - frequently the production of a million transistors costs only 100 times more than the production of 1000, that is, in the first case, the unit price of the transistor may be 10 times lower.
But in addition to cheapness, it is crucial to be technologically advanced, and in this area we are falling further behind. According to the Australian strategical Policy Institute (ASPI): "In 2025, China leads in 66 out of 74 (roughly 90%) of the world’s most critical and emerging technologies. “ Bad.
In terms of both the scale of production and technological progress, only a United Europe can be a competitor for China.
I repeat this as a mantra, but I will do it until Poles realize that the United States of Europe is our only chance to last in specified prosperity.
