[Infostock Daily= Senior Reporter Lee Hyung-jin] Samsung Electronics recently secured 90% of yield the percentage of successful products among products in the DRAM Tech Migration, which was conducted since January last year, and it was confirmed in the Infostock Daily news coverage gathering .
“Samsung has secured a meaningful yield at the level of 10 nano(1z) over the past year and a half,” said an official who is well aware of Samsung Electronics’ internal affairs. “This is significant enough to say that the technology that can rise to the top in the DRAM market is completed ahead of the full-scale 5G era,” he said.
The yield is different from the EUV (extreme ultraviolet) process announced by Samsung Electronics earlier.
It does not go through the EUV process, especially without expanding the factory, and has secured more than 90% yield.
Samsung Electronics has reportedly made every effort to secure yields by organizing a separate team to secure yields.
Since last year, Samsung Electronics has been preparing to produce 10 nano DRAM with tech migration.
Tech migration refers to the development of technological development by changing the operating system, equipment, and production materials.
The semiconductor industry is known to try tech migration in the form of using high purity production materials such as polysilicon and gas or replacing production facilities.
In the semiconductor industry, it is known that it is trying to migrate technology by using high purity production materials such as polysilicon and gas or replacing production facilities.
It is not easy to secure a certain level of yield because the process difficulty increases when new semiconductor technology is introduced every year like Samsung Electronics.
For this reason, the industry's assessment is that Samsung Electronics secured 90% of DRAM yields without EUV this time, in fact, solving the difficulty of extreme evil.
Samsung Electronics is expected to start converting its existing process line soon, as it has secured a yield rate in the EUV-free process.
In this 10 nano process, LPDDR5, which is essential for the millimeter wave (ultra high frequency band), which is a nickname of 28GHz frequency of 5G, can be produced. It is highly likely that the super-gap technology, which goes beyond Samsung Electronics' super-gap technology, will be realized more quickly.
“The size and speed of the chips produced in this 10 nano process is above expectations,” said another bright official inside Samsung Electronics. “The production cost is expected to make a significant difference compared to other companies,” he said.
