of systems technologies, products and applications. The initial
                                                             pains in setting up manufacturing and R&D infrastructure
                                                             will lead to long-term gains. India, unlike most countries, is
                                                             capable of massive R&D gains because of its large number of
                                                             top-notch academic institutions that have already produced
                                                             the very best global leaders that are heading up the largest
                                                             corporations in the world. All of this will happen only if India
                                                             can correct its manufacturing infrastructure in areas such as
                                                             materials, chemicals, gases, water and power, as well as correct
                                                             its deficiencies in R&D infrastructure.

        comprehensive and leading-edge R&D, consistent with the next-
        generation of global industry needs. This is beginning to happen at
        many IITs and the IISc as shown in Figure 5 as a result of my many
        trips to organize and form interdisciplinary faculty teams across
        India in these 12 SRTs.

        Status of integrated systems packaging in India
          India has some of the best academic institutions in the world.
        It also has young, energetic, innovative and hardworking faculty.
        These faculty from the IITs and the IISc shown on the Indian
        map (Figure  5) have already performed world class R&D in
        selective systems technologies. These areas include: compound
        semiconductors, microelectromechanical systems (MEMS),
        sensor and microfluidic research, photonic integrated circuits, low-
        temperature bonding of Cu to Cu, and 3D stacking with through-
        silicon vias (TSVs), advances in etching of nonconductive materials,
        electroplating through-glass vias (TGVs) for 3D, metal-based
        encapsulation for MEMS and solid-liquid interdiffusion (SLID)
        bonding, packaging of a wide variety of MEMS devices, stacking
        of ultra-thin complementary metal-oxide semiconductor (CMOS)
        devices, transfer of GaN devices onto Cu substrates, packaging-
        related educational programs, as well as an MTech program in
        semiconductors and packaging. These are all foundational world-
        class R&D and educational programs upon which to build new
        industry-driven programs.

        Summary
          India is poised to be a global player in the short term, and
        perhaps a global leader in the long term in integrated systems
        from R&D to manufacturing—serving both domestic and
        foreign markets. It already has world-class design and software
        expertise and, when combined with the new manufacturing and
        R&D initiative, it is bound to be successful in the total stack
