摘要:
A liquid resin material stored in a resin material cup is sent to a supply tank under pressure through a primary side supply pipe by increasing the pressure in a pressure tank. The supply tank is provided with a piston that is displaced in accordance with the amount of the resin material in the supply tank, and the resin material is quantified by the stroke of the piston. The quantified resin material is sent to a heating member through an evaporation side supply pipe, is evaporated by heating, and condenses on a substrate. The resin material is quantified by filling the supply tank with the resin material temporarily, and only the filling resin material is sent to the heating member. Therefore, an evaporation amount becomes constant, and as a result, the thickness of a resin thin film is stabilized.

A cap member (10) which is brought into contact with a nozzle forming surface of a recording head (15) to seal up the nozzle forming surface, and a wiping member (11) which may be brought into sliding contact with the nozzle forming surface of the recording head (15) are disposed on a cap holder (31). With progress of a cleaning operation in which ink is placed under a negative pressure, and sucked and discharged from the recording head, a cap retaining member (50) is moved upward and placed to a set state, whereby blocking the slanting and downward movement of the cap member (10). Then, the wiping member (11) located on the cap holder (31) slides on the nozzle forming surface to wipe the nozzle forming surface. To a flushing operation, the cap retaining member (50) is moved downward and placed to a reset state. In this state, the wiping member (11) does not slide on the nozzle forming surface.

An electronic field reduction in a corner of a trench section of a semiconductor is achieved by forming a p-type base region in a source area of an n-type drain region, and both an n-type source region and a gate leading region are formed in a surface area of the p-type base region separately from each other. A trench section is formed in both the source region and gate leading region to reach the drain region. Polysilicon is formed in the trench section and on the surface of a semiconductor substrate with a gate insulation film interposed therebetween and then thermally treated. An interlayer insulation film is deposited on the entire surface of the semiconductor substrate, and then contact holes reaching the gate leading region and the source and base regions in the peripheral portion of the trench section in the source region are formed. A source/base electrode which contacts both the source and base regions through one of the contact holes is formed. A gate electrode is formed which contacts both the gate leading region and the polysilicon in the trench through the other contact hole.

A method for maintaining a fluid ejecting apparatus including an ejecting head that has an ejecting surface in which a plurality of ejecting ports that eject fluid are formed, and a maintenance portion that performs maintenance processing to recover the ejection of fluid from the ejecting ports and that has a cap member and a wiping member. The method includes performing capping processing to put the cap member on the ejecting surface and to suck, and then wiping processing to wipe the ejecting surface with the wiping member, and performing the capping processing again and then waiting a predetermined time without performing the wiping processing.

A semiconductor device comprises a semiconductor layer which includes a terminate end part and a cell formation part that is surrounded by this end part, and a plurality of guard rings each of which is formed at the end part to surround the cell formation part. These guard rings are made shallower and smaller in width as they get near to the guard ring that resides at the outside position.
摘要:
A semiconductor device is characterized in that source electrode contact regions, each of which is formed of a first conductivity type source layer and a second conductivity type base layer in a surface of a semiconductor surface, are formed at respective intersectional points of a diagonally-arranged lattice, and in that a trench having a gate electrode buried therein is formed so as to snake through the contact regions alternately. By virtue of the structure, the trench arrangement and source/base simultaneous contact quality are improved, to thereby increase a trench density (channel density) per unit area.
