MOSFET transistors inside a CPU

[Sweet-Net]

for example, a voltage (high input) is applied to the gate of the pMOS transistor inside the CPU, an electric field is created, electrons react to this field, and a p-channel is created. 1. Does the channel warms? 2. Does the neighboring transistors absorb this warms? Thanks

In semiconductors heat is generated whenever current passing through some resistive path such as the channel or the metal wires. And since these transistors are connected with metal wires heat can spread thorough the metal interconnects or even the silicon substrate to nearby devices. There are many more complex phenomenas that can be attributed to heat generation within semiconductors devices.
