摘要:
In a method of forming a dielectric layer pattern, lower patterns are formed on a substrate. A first dielectric layer is formed on sidewalls and upper surfaces of the lower patterns and a surface of the substrate. A mask pattern is formed on the first dielectric layer to partially expose the first dielectric layer. The exposed first dielectric layer on upper surfaces and upper sidewalls of the lower patterns is partially removed and the removed first dielectric layer is deposited on surfaces of the first dielectric layer between the lower patterns, to form a second dielectric layer having a thickness greater than that of the first dielectric layer. The second dielectric layer on the sidewalls of the lower patterns and the substrate is etched to form a dielectric layer pattern. Accordingly, damage to the underlying layer may be reduced, and an unnecessary dielectric layer may be completely removed.

For fabricating a field effect transistor, an extra-doped channel region is formed below a surface of a semiconductor substrate. An opening is formed in the semiconductor substrate into the extra-doped channel region. A gate insulator is formed at walls of the opening such that the extra-doped channel region abuts the gate insulator at a bottom portion of the opening. The opening is filled with a gate electrode. Such an extra-doped channel region prevents undesired body effect in the field effect transistor.

Non-volatile memory devices include a tunnel insulating layer on a channel region of a substrate, a charge-trapping layer pattern on the tunnel insulating layer and a first blocking layer pattern on the charge-trapping layer pattern. Second blocking layer patterns are on the tunnel insulating layer proximate sidewalls of the charge-trapping layer pattern. The second blocking layer patterns are configured to limit lateral diffusion of electrons trapped in the charge-trapping layer pattern. A gate electrode is on the first blocking layer pattern. The second blocking layer patterns may prevent lateral diffusion of the electrons trapped in the charge-trapping layer pattern.

A particle adsorption device includes a chamber having an inlet and an outlet by which air can pass through the chamber, a support for supporting an adsorbent plate in the chamber, and at least one porous plate disposed in the chamber to control the air flow through the chamber and over a surface of the adsorbent plate. A sampling apparatus includes a particle counter which has a detector that is operative to count particles of a certain size contained in the air, the particle adsorption device, and a probe by which a sample of air is sequentially or selectively fed to the particle adsorption device and the particle counter. Thus, in a method for use in monitoring a manufacturing environment for potential contamination, particles of a certain size in the air can be counted, and particles in the air can be collected on the surface of the adsorbent plate. The collected particles can be analyzed to determine their shape and composition. Te source of the particles can be traced from data produced using the sampling apparatus.
