Cheaper chips thanks to water

Mass production of computer chips is a hazardous process and, as a statistic rule, a variable part of this production has to be disposed of for quality reasons.
The more complex the chip, the more chances there are it will end up in the bin. Of course this has consequences on the retail price, for the overall production cost remains the same regardless of the default rate.
One of the main chip manufacturer, TSMC, has found a new technique called "immersion lithography" which significantly reduces this rate. With this process, the burning of the silicium wafers takes place in a liquid and transparent material such as water. Another bonus is that the machines used for production will last longer. When this technology goes mainstream, we can hope a fall in the price of complex chips such as GPUs.
