During the recent past, several researchers [1] have designed the stacked integrated circuit (IC) layers on top of each other in order to integrate more devices on a single chip with improved performance. This advocated technique, known as three-dimensional (3D) die stacking, primarily results in higher transistor density, improved speed, lower power dissipation and area [2]. Traditionally, the connections were made through the multiple intellectual property cores on a single die (system on chip), multiple dies in a single package (multichip package), and multiple ICs on a printed circuit board [3]. Later on, system-in-package technology was introduced in which dies containing ICs are stacked vertically on a substrate. Another stacking technique is package on package that uses vertically stacked multiple packaged chips [4]. The latest development in this area is the 3D stacked IC using through silicon vias (TSVs), which employs a single package containing a vertical stack of naked dies and allows the die to be vertically interconnected with another die. TSVs are primarily referred to as a vertical electrical connection, or vertical interconnect access (via), that passes completely through a silicon wafer or a die. A TSV-based 3D IC offers various advantages in integrating a heterogeneous system onto a single platform as shown in Figure 4.1.
