Why aren't transistors stacked in silicon chips?
I have learned that silicon chips are manufactured with a base layer of transistors and upper layers of interconnects.
Why can't these upper layers of interconnects be replaced with additional ...

What substances have the lowest dielectric strength (volts/meter)?
All the tables of dielectric strength I can find are lists of materials that engineers use as practical insulators, and air is usually the least insulating thing on the list.
Where can I find a more ...

So even though the raw materials of semiconductors are cheap why is their cost so high and why don't we use conductor for the same job?
The materials used in making semiconductor are cheap and readily available then does the cost of processors so high can't we use metals like copper and iron which very good conductor for manufacturing ...

Can a semi-conductor cooler be powerful enough for a room? [duplicate]
I see semiconductors used for small fridges. I cannot find one large enough to cool a room (in place of a conventional Freon based, window air-conditioner). What engineering problems might a up scaled ...

Problem with relationship between shunt resistance and grain boundaries in a solar cell [closed]
Here is the correct answer from another stack website.
The higher shunt resistance means that higher the
polycrystalline lattice irregularity and many grain boundaries. This
means higher current ...

P-N junction depletion region
Before I explain my problem I'd like to mention I'm still green and about 2 weeks into these topics. I learned most of it from youtube videos, wikipedia and other science sites, so I'll be explaining ...

Why do transport containers for wafers open clockwise?
In the semiconductor industry and research, silicon wafers are transported in round plastic sample containers with a screw lid.
Other than any other screw top though, the lid always opens (releases) ...
