The silicon microchip and integrated circuit followed similar if shorter processes from invention to commercial realization.

The material absorbing the radiation can be human tissue or silicon microchips or any other medium (for example, air, water, lead shielding, etc.).

Several groups of scientists have already developed silicon microchips that can create artificial vision.

Quantum-effect devices had long since replaced the clumsy doped silicon microchips, and so computers had become orders of magnitude faster and better.

The way Proctor tells it, with a little background: The first silicon microchips were the size of a fingernail and had a million circuits.

Basically, a single-chip microprocessor allows an entire central processing unit (CPU) to exist on one silicon microchip.

But one technology may extend the life of the silicon microchip - it's called extreme-ultraviolet lithography, and it may keep silicon useful for a few years longer.

Is a silicon microchip the answer to combating retinal disease?

Indeed as pure silica it is the insulating element in the technology of silicon microchips.

The Harvard-M.I.T. group plans to use at least two silicon microchips.
