Types of Field Effect Transistor

Types of Field Effect Transistor

Types of Field Effect Transistor: In general, Three Types of Field Effect Transistor are namely, Junction field effect transistor (JFET) Metal oxide semiconductor field effect transistor (MOSFET) Complementary Metal Oxide Semiconductor (CMOS) Junction field effect transistor (JFET): The basic processes used for the fabrication of JFET are exactly similar to those used in the fabrication […]

Integrated Resistor

Integrated Resistors05

Integrated Resistor: In Integrated Resistor circuit design, the importance is given to the maximum usage of transistors. For example digital CMOS, nMOS and GaAs circuits are fabricated entirely with transistors and diodes. The Integrated Resistor are grouped into two groups ; one formed within monolithic IC and other composed of film resistors. The monolithic IC

Monolithic Diodes

Monolithic Diodes

Monolithic Diodes: Monolithic Diodes – The fabrication of diode is very straight forward. Generally any two terminals of the transistor are connected together to form one of the electrodes while the remaining terminal can be considered as remaining electrode of a diode. The different connections in transistor to utilize it as a diode are as

Fabrication of Monolithic IC

Fabrication of Monolithic IC: The cross-sectional view of an Fabrication of Monolithic IC and discrete planar transistor are as shown in the Fig. 1.17 (a) and (b) respectively. The main difference between Fabrication of Monolithic IC and discrete planar transistor is that collector contact in monolithic integrated transistor is at top, while in the discrete

IC Packaging Process

Integrated Circuit Packaging Process

IC Packaging Process | IC Package Types: After completing all the fabrication processes, several chips are ready on a wafer. Each of the chip is nothing but a complete circuit. Now the next step is to separate out these chips and package them individually. Using a diamond tipped tool lines are scribed along the rectangular

Metallization Process

Metallization

Metallization Process | Types of Metallization | Applications: Metallization Process in which a thin layer of metal is formed which is used to make interconnections between the components on the chip as well as interconnections between the components and the outside world. In general metallization applications are divided into three groups, Gate, Contact and Interconnects.

Diffusion Process in IC Fabrication

Diffusion Process in IC Fabrication: Diffusion is the oldest technique used to add impurity into the Substrate. The main aim of the Diffusion Process in IC Fabrication is to change  the Conductivity of silicon substrate over a depth. The Diffusion Process in IC Fabrication is used in bipolar device technology to form bases, emitters, collectors ;
