This cases series is intended for use in a technology management curriculum, and the companion Web site, http://www.darden.virginia.edu/it/explore/, provides a multimedia overview of the technology with the aid of 3-D animation to enhance the learning experience. The series brings to life the challenges faced when pursuing cutting-edge technology development. To bridge the chasm of a major technological discontinuity in the semiconductor industry, the leading firms have to confront challenges associated with intercompany cooperation and coordination in a setting replete with technological uncertainties. Only by doing so will the semiconductor industry be able to continue its adherence to Moore's Law. The A case UVA-BP-0423) leads students to formulate strategies for cooperative development targeting much-needed next-generation lithography systems. The B case places students in a position of evaluating what the lead firms (IBM, Intel, and Lucent) actually did.
