1.try to reduce size of transistor - SET-single electron transistor , Quantum DOTS
nano electronics related(currently 20-28nm channel length technology is coming in)
2.try to improve the speed of operation of transistor
3. try to reduce the Power of transistor -LOW POWER VLSI
4.try to make some figure out method using IC DESIGN AND 20nm-BIO-sensors-control and regulating in EYE OR EAROR BRAIN OR HEART OR LUNG OR LIVER OR KIDNEY OR NERVOUS SYSTEM
(find the area of appliaction where the current limitation can be ob=vercome using the knowledge u have or about to develop on your own)
5.try to make efficient Asynchronous circuits and Asynchromous processors
it will huge diff in speed and power consumed w.r.to Synchronous processor
6. try to make a new type of ADDER that add in half the delay time of available adder (this will just increase the speed of a processor by an amount u have reduced the delay)
7. u can work on efficient VLSI cad tool design or VLSI TESTING as it makes eats the time cost of semiconductor company
8. maipulation of phonons , photons to control them so that we make transistors , ICS and on ...on....
TRY TO OVERCOME current LIMITATION< PROBLEM OR DIFFICULTIES IN ANY FIELD(in vlsi itself also ) BY APPLYING UR VLSI BRAIN
--THEN U COULD HAVE DONE A VALID SOLID OBJECTIVE ORIENTED RESEARCH

The future of VLSI circuits depends on trend of channel length reduction. Available fabrication technologies deny more degradation in channel length, so nanoelectronics devices such as QCA (Quantum-dot Cellular Automata, SET (Single Electron Transistor), CNTFET (Carbon nano tube field effect transistors) and Benzene rings are candidates for replacement of conventional CMOS technology.
One can perhaps expect research to better harness the power of existing technologies instead of chasing the Moore's Law vector. We can expect that Multicore architectures will be a big part of this endeavor.
Low power design of any of the basic blocks(like DC-DC Converters,BUCK/BOOST Converter,LDO etc)power management block.Power management is one of the biggest issue now a days.
SETs, CNTFET,GRAPHENE FET, Channel length morphology, interfacial issues, high k etc. Besides this there specific applications Like Sensors, Actuators, Switches etc.
you can prefer to current mode building blocks(CMRR), design CMRR based circuits.
Basic Goals of VLSI design are: Speed improvement - size reduction - power dissipation reduction - and to make the electronics products affordable( cost ) to common people. Moreover , for fabrication of miniaturized device needs costly sophisticated equipment. Keeping all these in view we are to renovate / innovate the geometry of MOS devices along with gate engineering. We are to also think some alternative devices which may work on completely different principle different from BJT or MOSFET. TFET/CNTFET( not very promising) / SED/ SpinFET/ OFET may come in future in post CMOS era.

Area,power and clock frequency are vital components to be taken care of while designing today's chips and electronics products.There will always be trade off between area and power but one has to decode to whom should we give priority which is concerned with application specific?
The primary concern in the VLSI domain is the limitation of channel length limit. We have already reached a limit of channel length of about 20 atoms. So to speed up processing and integrate more transistors we should search for new ways, and this is the primary focus of future research.
