A deflector array includes a plurality of deflectors, which deflect charged particle beams, arrayed on a substrate. Each of the plurality of deflectors includes a single opening formed in the substrate, and each of the plurality of deflectors includes a pair of electrodes that oppose each other through the opening and are configured to deflect a single charged particle beam. The plurality of deflectors are arrayed such that a length of the pair of electrodes in a longitudinal direction thereof is not less than a distance between centers of two of the plurality of deflectors that are located nearest to each other. The plurality of deflectors is arrayed to form a checkerboard lattice, and two openings of the two of the plurality of deflectors overlap in the longitudinal direction.

This invention discloses a deflector array in which a plurality of deflectors which deflect charged particle beams are arrayed on a substrate. Each deflector includes an opening formed on the substrate, and a pair of electrodes opposing each other through the opening. The length of the pair of electrodes in the longitudinal direction is not less than the distance between the centers of two deflectors equivalent to the plurality of deflectors, which are located nearest to each other.

A process for fabricating a mold for an aspherical microlens having a desired aspherical and smooth surface, the lens having an effective diameter of 1 mm or smaller and a thickness of 0.5 mm or greater. A double-layer mask layer is formed on a single crystal silicon substrate, and anisotropic etching and isotropic etching are carried out using a first mask layer so as to form a concave portion that is a little smaller than the size of a desired microlens mold. Isotropic etching is then carried out using a second mask layer so as to enlarge the concave portion, thereby obtaining a microlens mold having desired dimensions.

The conventional semiconductor element testing equipment is arranged to position each probe accurately and need a burdensome operation for fixing, and includes only a limited number of electrode pads and chips to be tested at a batch. An equipment for testing a semiconductor element is arranged to keep each of electrode pads formed on a semiconductor element to be tested in direct contact with each of probes formed on a first substrate composed of silicon, one of electric connecting substrates disposed in the equipment. On the first substrate, each probe is formed on a cantilever and a wire is routed from a tip of each probe along a tip of the cantilever to the electrode pad formed on an opposite surface to the probe forming surface through an insulating layer.

A slider unit having a reading or reproducing head, with the head being adapted to float over a surface of an information recording disc. The slider unit includes a slider body having a flying height sensor with float surfaces on an underside thereof to generate a lifting force. A piezoelectrically or electrostatically controlled valve layer may be positioned over a vent communicating between an upper surface of the slider, with the vent opening to a recess for generating a negative lift component at an underside of the slider unit. The slider body is made from a ceramic base portion and includes a semiconductive insert portion of, for example, silicon or a photosensitive glass with an adjustment device being formed by utilization of microfabrication techniques such as deposition and etching.

The invention relates to a gas sensor for measuring an air-fuel ratio of an air-fuel mixture of an internal combustion engine and to a method of manufacturing the gas sensor. The sensor of the invention comprises: a solid state electrolyte layer made of an oxygen ion conductive metal oxide; a first electrode of a porous thin film having the catalyst function which was coated on one surface of the solid state electrolyte layer; a second electrode of a porous thin film having the catalyst function which was coated on the other surface of the solid state electrolyte layer; an electrode shielding layer made of a sintered material of ultra fine particulates whose average grain diameter is 1 .mu.m or less which covers the surface other than the region of a predetermined area of the second electrode; and a gas diffusion layer made of a porous electric insulative metal oxide which covers the region of the predetermined area of at least the second electrode.
