INTRODUCTION In electronics, a three-dimensional integrated circuit is a chip in which two or more layers of active electronic components are integrated both vertically and horizontally into a single circuit. In contrast, a 3D IC is a single chip in which all components on the layers communicate using on-chip signaling, whether vertically or horizontally.
To continue the legacy of Moore's law There is rapid growth in software and IT industry which requires complex but also compact hardware. To reduce delays which will otherwise occur between different IC’s on a system. Also helps reduce cost and power required. IDEA OF 3D IC
WHY 3D ARE BETTER THAN 2D CHIPS Increase in performance increases complexity which increases no of gates which in turn will increase the number of transistors. Considering this only in two dimensions will lead wastage of area . This will also increase the delay. There will be to much connection complexity which might cause hindrance in transfer of signal due to the resistance of the wire and capacitance formed. Whereas 3D IC’s can improve the performance save area and increase the transistor density
Differences
3D IC manufacturing process Monolithic Wafer on wafer Die on wafer Die on die
Monolithic process Electronic components and their connections (wiring) are built in layers on a single semiconductor wafer, which is then diced into 3D ICs. There is only one substrate, hence no need for aligning, thinning, bonding, or through-silicon vias.
Wafer on wafer Electronic components are built on two or more semiconductor wafers, which are then aligned, bonded, and diced into 3D ICs.
Die on a wafer Electronic components are built on two semiconductor wafers. One wafer is diced aligned and bonded onto die sites of the second wafer.
Die on a die Electronic components are built on multiple dice, which are then aligned and bonded. One advantage of die-on-die is that each component die can be tested first, so that one bad die does not ruin an entire stack
Advantages of 3D architecture 3D integration can reduce the wiring reduces the capacitances and resistance. Low power dissipation Low chip area High transistor density It more cost effective then 2D integration.
challenges IC testing and yielding Heat removal Power delivery Design complexity testing
Applications of 3D IC Mobile devices (Soc) Wearables Medical industry Defence industry Automative industry
The concept of SOC The system on chip design is the major application of the 3D IC It is a piece of tech containing the entire system on a single chip. In soc design the processing elements the memory the RF equipment and many more devices are connected in 3D using TSV’s. This kind of design dominate the mobile and desktop industry these days
