It is, therefore, applicable not only to the failure analysis but also to the in-line inspection and monitoring. The basic idea of the technique is detection of a magnetic field produced by a laser-beam-induced current by using a HTS (high-temperature-superconducting) DC-SQUID (superconducting quantum interference device) magnetometer. The intensity of magnetic flux detected by the SQUID magnetometer is imaged, while scanning a laser beam and a sample relatively. The spatial resolution of this scanning laser-SQUID microscopy (\"laser-SQUID\" for short) is expected to be much better than conventional SQUID microscopy because it is limited by the laser beam diameter: that of the conventional SQUID microscopy, on the other hand, is limited by the size of the detector and the distance between the detector and a sample. An experiment using a prototype system has showed that the spatial resolution is about one um. Other experiments have demonstrated the application of the laser-SQUID to LSI inspection and analysis.","PeriodicalId":202620,"journal":{"name":"Digest of Papers.

Namely, the miniaturization of the design rule pushes the pattern sizes in the peripheral region as well as in the cell region into the resolution limit of exposure tools. Although it is common to use single exposure for lithographic layer formation, an ArF double exposure technique (DET) strategy, based on manual OPC and an in-house simulation tool, HOST (Hynix OPC simulation tool), is suggested as a possible exposure method for overcoming the limit and its results on wafer are shown. The in-house simulation tool used in this paper can predict the wafer pattern and process margin of a lithographic layer and shows good validity in the ArF process.","PeriodicalId":202620,"journal":{"name":"Digest of Papers.

Among the current sensors, engineered transmembrane protein pores have been advantageous candidates for sensing elements. This sensor has two electrolyte-filled pools, which are separated by a lipid bilayer having a protein pore (e.g. /spl alpha/-hemolysin). The specimen molecules place in one of the pools can stochastically pass via the pore. They produce a fluctuating binary response in the transmembrane ionic current (Bezrukov et al, 1994; Li-Qun Gu et al, 1999). Instead of the protein pore, we have proposed use of nanometer-sized holes in a SiN/sub x/ membrane as a sensor head. We have fabricated the biomolecular sensor with nanoholes using a Si bulk micromachining technique (Fertig et al, 2000) and observed the ionic current via nanoholes.

An oxygen plasma or chromic acid was used to convert the plastic channel surface from hydrophobic to hydrophilic for the separation of molecules in aqueous solution. The channel was scaled by thermal bonding of a cover piece of the same plastic material. The microfluidic device for electrophoretic separation and fluorescence detection had a separation channel 50 /spl mu/m wide, 20 /spl mu/m deep and 3.0 cm long.

These elements in the resist are effective to get a high sensitivity and to suppress the influence of the emitted secondary electrons from a Si substrate, as well as to improve the resolution. In addition, the absorbed power spectrum in these resists becomes narrow comparing to the normal one consisted of C, H, and O.

Such excess carriers are induced by hot electrons generated by a strong field gradient at and nearby the source and drain. Suppression of the floating body effects is important for realization of SOI-MOSFETs. There are two types of SOI substrate: one is a fully depleted (FD) substrate, where the SOI layer is <50 nm, and the other is a partially depleted (PD) substrate where the SOI layer is >100 nm. PD substrate fabrication is simple, but an SOI-MOSFET on PD substrate has kinks and floating body effects (Colinge, 1998). A PD-SOI-MOSFET with body-tied structure is the simplest way to suppress the floating body effects, in which body contact electrodes are put on the side of the SOI body and tied to the source contact. In our recent studies, floating body effects in parallel connected PD-SOI-MOSFETs were induced by nuclear microprobe irradiation (Takai et al, 1999; Iwamatsu et al, 2000). The effectiveness of the body contact electrodes was clarified. In this study, instability of parallel and single PD and FD SOI-MOSFETs has been studied by experiments and two types of three dimensional computer simulations.","PeriodicalId":202620,"journal":{"name":"Digest of Papers.
