Calculating chip junction temperature based on case temperature
As far as I know one can calculate a chip’s (Diode, Transistor..) junction temperature rise with the consumed power and the thermal resistance Rth.
Is there a way to calculate the junction ...

Why do bare die chips (MOSFET) have a maximum storage temperature?
As far as I understand, a chip in general and a MOSFET in particular has a maximum operating temperature (let‘s say 125 °C or 150 °C for Si) because above that temperature the risk increases of ...

Estimate temperature for silicon (p-n junction)
I need to estimate the temperature at which p-n junction made of silicon lose it rectifying characteristics. (\$N_A=N_D=10^{15}\,cm^{-3}\$)
\$E_G\$ is independent of the temperature and are 1.12 eV ...

Dependency of conductivity on temperature of extrinsic semiconductor
For an extrinsic semiconductor, how can we explain the following dependency of conductivity on temperature as shown here:
My thoughts:
At 0 K there is no energy available, hence no electrons can flow ...

Could modern electronic chips (e.g. ARM and Intel processors) operate for millennia at sufficiently low temperatures and clock speeds?
More broadly, what the practical maximum a modern silicon chip could be expected to last (assuming it operates at some temperature above 77K, and it has stable power)?
For example, I expect diffusion ...

Why is the temperature range of industrial and military products so high?
From Wikipedia the common temperature range for electrical components is:
Commercial: 0 to 70 °C
Industrial: -40 to 85 °C
Military: -55 to 125 °C
I can understand the lower part (-40°C and -55°C) ...
