An ion implantation apparatus according to an embodiment includes an ion implantation unit, a position detection unit, a charge supply unit, a current value detection unit, and a determination unit. The ion implantation unit scans the surface of a substrate with an ion beam containing positively charged ions and implants the ions into the substrate. The position detection unit detects the scan position of the ion beam on the substrate. The charge supply unit generates a plasma, emits electrons contained in the plasma, and supplies the electrons to the substrate. The current value detection unit detects a current value that changes in accordance with the amount of electrons emitted by the charge supply unit. The determination unit determines the charge build-up state of the substrate based on a change in the current value, the change being accompanied by a change in the scan position.

Ion implantation apparatus and method of determining state of ion implantation apparatus

The formation of an interlayer insulating film above a substrate, the formation of an insulating film of an organic material on the interlayer insulating film thereafter, and the irradiation of the insulating film of an organic material and the interlayer insulating film with electron beams, thereby curing at least the insulating film of an organic material, are proposed.

Method of manufacturing semiconductor device

A method of manufacturing a semiconductor device bakes a first semiconductor substrate on which a sacrifice film is formed in a reaction chamber to preliminarily coat an inner wall of the reaction chamber with a component of a gas generated by the sacrifice film, and bakes a second semiconductor substrate on which a predetermined film including the same component as that of the sacrifice film is formed in the preliminarily coated reaction chamber, while irradiating electron beams on the predetermined film to change quality of the predetermined film.

A semiconductor device manufacturing method comprises forming a first insulating film including silicon, carbon, nitrogen, and hydrogen above a substrate in a first chamber, carrying the substrate into a second chamber other than the first chamber, and discharging a rare gas in the second chamber, and forming a second insulating film including silicon, carbon, oxygen, and hydrogen above the first insulating film after the discharging the rare gas.

Disclosed is a semiconductor device comprising a semiconductor substrate, a porous insulating film formed above the semiconductor substrate, the porous insulating film having a relative dielectric constant of 2.5 or less and including a first insulating material, at least a portion of pores in the porous insulating film having on the inner wall thereof a layer of a second insulating material which differs in nature from the first insulating material, and a plug and/or a wiring layer buried in the porous insulating film.

Semiconductor device fabrication method

In a parallel-plate type plasma processing apparatus including an upper electrode having a plurality of gas introducing inlets and a support table serving as a lower electrode opposed to the upper electrode and having a silicon wafer thereon, the open ends of the inlets are expanded in their diameter directions.
