The story of the engineers who shaped the world's most powerful chip machines How do you transform a hopeless research and business activity into a billion-dollar machine and a world-leading company? The Dutch enterprise ASML pulled it off, and the book ASML’s Architects by renowned technology writer René Raaijmakers reveals exactly how. ASML's Architects travels back to the origins, struggles, success factors and sheer luck of a company that was barely alive at the beginning of the 80s, yet managed to become the uncontested world leader in chip lithography. Today, ASML determines the pace at which all information technology advances. The book covers the technology and the business, but the real story is in the people behind them. Throughout its pages, the interviewed engineers, scientists and managers speak frankly about their struggles, their fights and the grueling teamwork behind the scenes.
