You said u r enjoying ur role and successful in it.
If it's true my personal suggestion will be to stay in software side and upskill to reach a height.
If ur mind is more managerial than technical then join 1y mba and rejoin at 2x-3x salary.
Coming to semiconductor or vlsi industry, It's highly paid due to niche knowledge required and demand-supply game.
Physical Design, Soc level roles, Memory design, AE and Circuit r n d are few highly paid jobs in VLSI. These are comparable to sde 2 or 3 salary.
All above roles are highly demanding and need high iq with Focus. Else single mistake has huge oc
But there are many roles which are low paid also like tech writer, cad and few front end roles.
Make sure u decide as per ur skills and interest not by what market is offering.
Happiness>Money.
