A capacitor capable of being incorporated into a packaging substrate, which capacitor includes a high-dielectric-constant layer, and an upper electrode layer and a lower electrode layer sandwiching the high-dielectric-constant layer from the upper side and the lower side. A packaging substrate containing the capacitor, and a method for producing the same are also provided.

Thin film capacitor, high-density packaging substrate incorporating thin film capacitor, and method for manufacturing thin-film capacitor

A silica-based interlayer insulating layer having a low dielectric constant is formed with SOG material on a substrate, in which a wiring-layer forming space is then formed. If necessary, a UV ray irradiation is performed under an oxidizing atmosphere. A Si&#x2014;OH bond is formed on a surface of the insulating layer. A monomolecular layer film is then adhered to the inner surface of the space, which is then modified to be a catalyst with a solution containing Pd compound. On the catalyst monomolecular layer, a copper-diffusion-resistant film is formed by electroless plating, on which a copper plate is then formed as a wiring layer.

Semiconductor multilayer wiring board and method of forming the same

An object of the present invention is to provide a low cost, high performance, thin structure rotary motor for driving medium used in magnetic disk drive unit, optical disk drive unit or the like, in order to improve the productivity of terminating processing and the reliability of the coils. Magnetic materials which are divided to a plurality of blocks or divided corresponding to respective magnetic pole teeth are connected by means of thin portions. The respective magnetic pole teeth are wound continuously with wire without cutting the wire at the positions in which the thin portions are connected. When a stator is assembled, a plurality of blocks or magnetic pole teeth are disposed on a substrate by separating or bending the thin portions.

This invention provides a small-sized and easy assembling head positioning apparatus having a coarse moving mechanism and fine moving mechanism, by which the desired fine moving accuracy is easy to attain. A head positioning apparatus has a first stepping motor, a lead screw, and a cylindrical rack for coarse moving. The cylindrical rack is formed by rotating a rack around the axis of the lead screw and is provided with the lead screw. The head positioning apparatus has a second stepping notor and gears for reducing the speed of the rotation of the second stepping motor for fine moving means, and fine moving is carried out by moving the cylindrical rack by the gear. The lead screw is provided so that the first stepping motor could be moved in a X1, X2 direction in the fixed moving range.
