A chemical treatment apparatus and a method for performing a chemical treatment of a wafer, etc., by supplying a chemical via a cell. The apparatus includes a cylindrical inner cell and a cylindrical outer cell with open ends disposed at an outer circumference of the inner cell. The outer cell is axially movable to vary the width of a slit formed between a bottom end of the outer cell and a top surface of the substrate-holding means by the axial movement, thereby adjusting the discharge rate of the chemical and varying the pressure of the chemical.

Chemical treatment method

A filter is formed by a sintered non-woven metal fiber cloth adapted to be installed in a liquid passage, and, in the filter, a substance sticking to the surface of metal fibers which is present in the outermost part of the filter and in the vicinity thereof is removed together with the surface layer of the metal fibers.

Filter, liquid discharge head utilizing the same, and producing method therefor

A glass circuit substrate wherein nuclei of Pd (palladium) are placed on a glass substrate and a plating layer of Pd--P (palladium--phosphorus) is placed on the nuclei. A fabrication method of the glass circuit substrate comprises steps of forming nuclei of Pd on a glass substrate; and therefore forming a plating layer of Pd--P on the nuclei.

Glass circuit substrate and fabrication method thereof

A substrate wherein a layer comprising a principal component of nickel and a layer comprising a principal component of palladium are deposited on a glass substrate and wherein an electroconductive layer is deposited on the palladium layer.

Substrate and method for producing it

A delivery member has a substrate material, a first coating film containing a filler and formed by electrodeposition on a substrate material, and a second coating film composed of an organic coating film formed on the first coating film.

Delivery member, and apparatus employing the same

A delivery member has a substrate and, provided thereon, an eletro-deposition coating film containing an organic powder. By this configuration, a delivery member having a homogeneous coating is formed. Stress is therefore uniformly distributed and the coating is resistant to wear. The delivery member can be made in a variety of different forms and can be used in many different types of apparatus.

Delivery member and apparatus making use of the same

A delivery member comprises a substrate and, provided thereon, an electro-deposition coating film containing inorganic powder. The inorganic powder may be selected from the group consisting of a ceramic powder, a metal powder, and a ceramic powder whose particle surfaces are coated with a metal.
