原子极限：IBM 0.7纳米设计挑战芯片物理边界

With tech giants on a mission to create smaller, faster, and more efficient semiconductors, the industry has long faced a fundamental constraint: the laws of physics. Traditional scaling has been approaching hard limits, but IBM Research has announced a breakthrough that challenges those boundaries and could unlock a whole new generation of chip physics. SUB-1 NANOMETER CHIPS At a press conference at the end of June, IBM Research unveiled the world’s first sub-1 nanometer chip technology, a 0.7-nanometer (7-angstrom) node built on a revolutionary three-dimensional architecture called nanostack. This is not marketing hype. …
