Professor Soldier Systems Center. We use your LinkedIn profile and activity data to personalize ads and to show you more relevant ads. Fabrication Technology. Taking into account packaging costs, the total manufacturing costs of supplying a BiCMOS chip ranges from 1.1-> 1.3 times that of CMOS. In the following, a brief introduction into integrated circuit fabrication will be given: the basic fabrication steps are highlighted (Section 1.1.1) and a CMOS process sequence is summa-rized (Section 1.1.2). A similar procedure can be utilized for the planned of NMOS or PMOS or CMOS devices. If so, share your PPT presentation slides online with PowerShow.com. 3. Provide separate optimization of the n-type and p-type transistors 2. All the devices on the wafer are 1(a). In this process, we with a substrate of high resistivity p-type material and then create both n-well regions. 1(c ).) The n- well, the p- substrate and the p+ source of the n-transistor forms another parasitic npn transistor T2. We now return to the generalized fabrication sequence of n-well CMOS integrated circuits. BiCMOS. layer thicknesses are determined by the CMOS process.
