Solid State Devices • Silicon – Doping • n-type, p-type silicon – Carriers • electrons and holes • P-N junctions – 2 terminal devices • Transistors – Bipolar Junction Transistors (BJT) – Metal Oxide Semiconductor (MOS) • 4 terminal devices • Main emphasis of this class
Integrated circuits • n. MOS and p. MOS devices • Modeled as on-off switches – But a lot goes on inside! • Complementary MOS (CMOS) circuit design methodology – Most common and widely used technique – But several other interesting techniques exist
Moore’s Law Courtesy: Intel, http: //www. intel. com/technology/mooreslaw/
Moore’s Law continued. . • Number of components in an integrated circuit double every 2 years • Signifies increase in computing capacity, memory and speed exponentially
MOS structure • n-channel • p-channel
Technology nodes • Scaling – 0. 25 um, 0. 18 um, 90 nm, 65 nm, 45 nm, 32 nm… • Pitch – Gate length – Device sizes – Frequencies
Current Computing Capabilities • Intel’s 80 -core processor: ~Terra flops • Over a billion transistors per chip • 4 -5 GHz chip clock
Issues and challenges of VLSI today • High Power dissipation • Faster operation • Methodologies to address these issues
Looking ahead • CMOS technology – Stable and well understood process • Future technologies – Nanodevices – Molecular devices – Single electron devices – Quantum dots – Many more… • The future is basically yours to invent!
