Micro Electro Mechanical Systems
1. MEMS the full name is Micro Electro Mechanical Systems and this in a way merging, are today and lot of work is pingo around the globe on MEMS Microsystems.
2. It has got enormous application MEMS refer to collection of seconds and actuators that can send its environment.
3. It has the ability to read changes in that environment with the one of a micro circuit control.
4. They include, in addition to the conventional microelectronics packaging, integrating antenna structures command signals into microelectromechanical structures for desired sensing and creating functions.
5. The system may also need micro power supply, micro relay and micro signal processing units.
6. Microcomponents make the system faster, more reliable, cheaper and capable of incorporating more complex functions and with this microcomponents buy all electrical and industrial access ans product
7. Now, the MEMS topic or Microsystems is an offshoot of the microelectronics and so to start the course on MEMS and Microsystems, we start from microelectronics.
8. let us look back little bit into the back of the present MEMS which is microelectronics and we will look into the story on microelectronics.
9. The three scientists who are the Bardeen, Brattain and Shockley from the Bell Laboratories and you know these three scientists first discovered the Point Contact Transistor which is in 1947.
10. The Jack Kilby and he invented integrated circuit in 1958. He got again Nobel Prize for this particular device in the year 2000.
11. So from that time onwards people are not seeing back and they are proceeding forward, particularly in the context of miniaturization of different components and making the integrated circuits.
12. Now if we look back to compare the revolution in the integration of The components, we have to go back to the first transistor which is also monolithic and that was made in 1960s, where four BJTs and several resistors are connected together with some metal line.
13. We can see the metal contact, metal born pad and the four transistors and Several resistances were integrated to get some functions off to get some circuit.
