CMOS fabrication process

Semiconductor Fabrication Processes

·        Front-End Processing (Wafer fabrication)
·        Back-End Processing (Assembly and Testing)

Semiconductor Applications
  • Personal Computer--- Desktop Computer (DT)  /
                      Notebook (NB)
  • Communication---
                   ADSL  / Cable Modem  /
                     IEEE802.11X / Bluetooth  / VoIP
  • Consumables---
                   Game  / DVD /  Digital Camera 
  • 3C merge--- Digital Home

Types of Chips

       Dynamic Random Access Memory chips (DRAMs) - serve as the primary memory for computers
       Microprocessors (MPUs) - act as the brains of computers.
       Application Specific Integrated Circuits (ASICs) - are custom semiconductors designed for very specific functions
       Digital Signal Processors (DSPs) - process signals, such as image and sound signals or radar pulses.
       Programmable memory chips (EPROMs, EEPROMs, and Flash) - are used to perform functions that require programming on the chip.
