After decades of research and trillions of dollars of investment, engineers have enabled extremely powerful computers that fit in our pockets - smartphones. This is achieved by making nanometer sized patterns on silicon to make tiny computer chips.
Precise control over silicon chemistry can be used to create nanometer sized holes with various applications. If the silicon surface is not controlled, strange shapes such as the star shape can be carved out of the silicon.
