Target dates are critical when the semiconductor industry adds small,enhanced features to our favorite devices by integrating advanced materials onto the surfaces of computer chips. Missing a target means postponing a device's release, which could cost a company millions of dollars or, or worse,the loss of competitiveness and an entire industry. But assembly target dates can be challenging because the final integrated devices, which include billions of transistors, and must be flawless - less than one defect per 100 square centimeters.
