摘要： An electron beam apparatus comprises an electron beam source, a unit for irradiating an electron beam (6) on a specimen (12), a detector (30) for secondary electrons, an electrode (7) for generating an electric field sufficient to draw out secondary electrons in a recess in the specimen from the recess, and a unit (2) for generating a magnetic field for focusing secondary electrons drawn out of the recess. With this construction, the secondary electrons drawn out of the recess by the electric field reach the detector without being attracted by the electrode. By adopting this construction, a contact hole of high aspect ratio formed in a semiconductor device and having a small diameter and a large depth can be observed.

摘要： A network communication method (and system) enables received data to be transferred directly to the user data region, thereby eliminating the need to perform data copy operations. Packets are each provided with received region assignment information (port ID) for showing the region in which the packet is to be received and/or division information for dividing the packet. The region which is to receive data contained in the packet is determined from a port table and conversion tables, and the packet data is transferred to the region directly.
