摘要:
The present invention provides a cross-linking agent capable of preventing formation of scum from a bottom anti-reflective coating, and also provides a composition for forming a bottom anti-reflection coating containing the agent. The cross-linking agent is a nitrogen-containing aromatic compound having at least one vinyloxy group or N-methoxymethylamide group, and the composition contains the cross-linking agent. The cross-linking agent of the formula (1) can be produced by reaction of a nitrogen-containing aromatic compound, a halogen compound having a vinyloxy group or N-methoxymethylamide group and a basic compound.

摘要:
A vertical heat processing apparatus for performing a heat process on a plurality of target substrates all together includes a vertical process container configured to accommodate the target substrates and having a transfer port at a bottom; a holder configured to support the target substrates at intervals in a vertical direction inside the process container; and a heater disposed around the process container, and configured to supply heat rays through a sidewall of the process container, so as to heat an interior of the process container. A thermal buffer member is disposed between the heater and a lower end side of the process container to surround the lower end side, and is configured to decrease transmissibility of the lower end side for heat rays between the heater and target substrates inside the process container.

A clean gas circulates to pass through a loading area provided below a vertical heat treatment furnace. The clean gas unidirectionally flows through the loading area. After completion of wafer processing, a wafer boat lowers from the heat treatment furnace to the loading area, where the wafers are removed from the wafer boat. Subsequently, a clean gas jetting nozzle arranged in the loading area jets a clean gas toward the emptied wafer boat. Fragment of thin film which may readily peel off are blown away from the wafer boat, and are discharged out of the loading area together with the unidirectional flow. Thus, it is possible to avoid wafer contamination due to the unexpected peel-off of thin film fragments from the wafer boat.

A magneto-optical recording medium comprises a substrate, and a magnetic multilayer 4 on a surface side thereof. The magnetic multilayer comprises an amplifying layer A.sub.1 and a recording layer R.sub.2 which are laminated together and are each a magnetic layer. A nonmagnetic intermediate layer I.sub.12 is interleaved between the amplifying layer A.sub.1 and the recording layer R.sub.2 to couple them magnetostatically. The nonmagnetic intermediate layer I.sub.12 is made up of a metal oxide and has a thickness of 2 to 30 nm. The magnetic field intensity needed for magnetic field modulation reading or light modulation reading can be lowered.
