    摘要: An electrochemical etching system has an etching bath for holding an n-type silicon substrate with a first surface of the substrate in contact with hydrofluoric acid, an electrode positioned in the hydrofluoric acid, a power source having a positive pole connected to the silicon substrate and a negative pole connected to the electrode, and an illumination unit having a light source for illumination of a second surface of the silicon substrate. The illumination unit illuminates the second surface of the silicon substrate with an illumination intensity of 10 m W/cm2 or more. A ratio of a maximum illumination to a minimum illumination of the second surface of the silicon substrate is 1.69:1 or less. With the etching system, pores and/or trenches of a certain size and shape can be formed in an entire area of the silicon substrate having a diameter of more than three inches.

    摘要: An atmospheric pressure plasma treatment apparatus includes a moving unit configured to relatively move an atmospheric pressure plasma treatment head and member to be treated, gas supply units configured to supply a reaction gas and a curtain gas, and a control unit. When the atmospheric pressure plasma treatment head and the member are relatively moved, the control unit performs control to increase a flow rate of the reaction gas and the curtain gas from an opposite direction side of a relative moving direction of the member with respect to the atmospheric pressure plasma treatment head and reduce a flow rate of the reaction gas and the curtain gas in the relative moving direction side of the member compared with the flow rates of the reaction gas and the curtain gas flowing when the atmospheric pressure plasma treatment head and the member are not relatively moved.

    摘要: A semiconductor pressure sensor comprises a silicon support substrate (1), an insulating layer (2) formed on the silicon support substrate (1), and a silicon thin plate (3) formed on the insulating layer (2). A through-hole (1a) extending in the thickness direction of the silicon support substrate (1) is formed in the silicon support substrate (1). The silicon thin plate (3) located on an extension of the through-hole (1a) functions as a diaphragm (23) that is deformed by an external pressure. The insulating layer (2) remains over the entire lower surface of the diaphragm (23). The thickness of the insulating layer (2) decreases from the peripheral portion toward the central portion of the diaphragm (23). This provides the semiconductor pressure sensor capable of reducing both the offset voltage and the variation of output voltage caused by the variation of temperature and its fabrication method.

    摘要: A plasma generating apparatus irradiates plasma on a treatment object. The plasma is generated under gas pressure equal to or higher than 100 pascals and equal to or lower than atmospheric pressure in an inter-electrode gap between a first electrode to which a power supply is connected and a second electrode arranged to be opposed to the first electrode and grounded. The first electrode has a structure in which the first electrode is retained on a grounded conductive retaining member via a solid dielectric provided on a surface not opposed to the second electrode, and a conductive film is continuously provided on a surface in a predetermined range in contact with the conductive retaining member and a surface in a predetermined range not in contact with the conductive retaining member on a surface of the solid dielectric.
