Is a printing process in which an image is photographed through a screen on to a sensitized printing plate that after development is etched.?

The printing process you're describing is known as photogravure. In this technique, an image is transferred onto a sensitized printing plate through a photographic process using a screen. The plate is then developed and chemically etched to create an image that can be used for printing. This method is often utilized for high-quality image reproduction in various print media.


How does an electronic etching machine work?

It scratches a thin layer of the surface off whatever is being etched, and leaves a pattern behind which differs from the smooth surface, revealing the design.


What is chemical etching in PCB manufacturing process?

The board is printed with the negative (in the sense of a photographic image) of the design that is desired on the finished board, in a material that is impervious to the solvent that will subsequently be applied to the board. When that solvent is applied the parts of the board that have not received the printed image are etched away leaving the desired circuitry.


What are integrated circuits are and why are they used?

A long time ago, after ways to make semiconductors were discovered - around 1955 - circuits were made by using a separate transistor to perform each function. That took a lot of real estate on a circuit board and meant severely decreased functionality when handling high frequencies. Nowadays all of those transistors and their associated circuit components can be laid out and etched into an area that is less than the size of the point of a pin, which is why they are called INTEGRATED CIRCUITS. The material that is used is a wafer of specially-prepared semiconductor material that has been doped differently in various nano-layers to allow the various circuit elements to be formed by selective etching.


What lithography technique used in microfluidics?

Most microfluidics use "standard" lithography techniques for patterning hard substrates such as glass or silicon. This would entail spinning photoresist, then exposing and wet etching in KOH (silicon) or HF (glass) or dry etching in a reactive ion etcher or deep reactive ion etcher. Soft lithography is also common in microfluidics where a mask is created using a hard material such as patterned SU-8 or etched glass. A polymer such as PDMS is then cast on the mold to create the microfluidic features.

Do all diamonds now have identifying numbers etched on them?

Not all diamonds have identifying numbers etched on them. It depends on whether or not the manufacturer chooses to have it done. You can have your diamond etched on your own if you want to.


What is a small piece of semiconducting material on which integrated circuits are etched?

A printed circuit board. abbrev- PCB. A PCB is thin copper attached to a non-conductive material. No, a printed circuit board is not a semiconducting material. Integrated circuits are created on a substrate, usually silicon or sapphire.
