Carbon laser peel is also one of the main methods of getting rid of acne and reducing the oil produced by our face.

The hard substrate is then removed, beneficially by laser lift off.

This is also a type of non-ablative laser treatment.

Lasering removers hair in one treatment but is expensive.

The laser surface is provided with a mask masking away parts of its surface to be prevented from dry etching.

Disclosed is a dry etching method which enables to reduce etching products in the etching process and improve in-plane uniformity with respect to the etching object.

Methods for forming vias in glass substrates by laser drilling and acid etching are disclosed.

Disclosed is a resist stripping agent which has excellent stripping properties, which has no flammability and therefore is safe, and which does not cause corrosion of a conductive material and therefore has excellent anti-corrosion properties.

A fresh stripper liquid is suitably added to the stripper liquid from which the resist components have been removed, and the resultant stripper liquid is reused in the stripping step.

The laser can implement multiple functions in a single operation, including cutting, drilling, notching and etching.

The present method is a method of electrochemical stripping analysis comprising an electrolysis step and a stripping step.

A robot blaster is positioned at the end of the extendable arm and performs the media blasting.

The etching rate ratio between palladium and gold (etching rate of palladium/etching rate of gold) is not less than 1.

The etching result is measured and at least one etching parameter (TZ,TA,v,cS,cFe,B,p) is automatically modified according to the measurement of the etching result in order to improve etching performance.

The stripping nozzles with flow of fluid loaded with solid particles can form a C- or D-shaped stripping front, causing a difference in stripping efficacy.
