What are things that electronics and telecommunication engineers (ECE) know while other engineers don’t?

Apple’s iPhone 5 is a product. Everyone knows this.

Many people don’t realize that the iPhone 5 has a 4G chip from Qualcomm, Flash memories chips from Hynix Semiconductors Korea, audio chip by Cirrus Logic, and Touch screen controller chip of Texas Instruments.

Complex chips that are used in mobile phones may contain transistors greater than 1 billion, but their size would be 3oo sq. m or (1.8cmx1.8cm). The Intel i7 processor, for example, has 731 million transistors. It measures 263 square meters. It is clear that transistors are very tiny.

If you compare the size of a transistor to the length of a human’s hair (100um), then it can be said that 28 nm technology can place approximately 3500 transistors along its length. This is how tiny a transistor can be! !

International Technology Roadmap for Semiconductors, (ITRS), states that we have reached 14 nm technology in 2014. We will be able to work with 10 nm technology by 2016.
