Filed:

Apr 22, 2003

Appl. No.:

10/420593

Inventors:

Chao Peng Chen - Fremont CA, US
Chunping Luo - Milpitas CA, US
Stuart Kao - Fremont CA, US

Assignee:

Headway Technologies, Inc. - Milpitas CA

International Classification:

G03F007/00

US Classification:

430296

Abstract:

As feature sizes approach 0. 1 μm or smaller, reduction of line edge roughness (LER) becomes increasingly important. Significant reductions in edge roughness have been achieved by applying a second Ebeam exposure after the initial one that is used to define the pattern. After this second blanket exposure a longer heat treatment and a stronger development process than before are used. In addition to reducing edge roughness the disclosed treatment allows the CD to be reduced under tight control since the amount of CD reduction is proportional to the second Ebeam dosage.

US Classification:

430320, 430313, 360324, 216 22, 20419234

Abstract:

The series resistance of a CPP GMR stack can be reduced by shaping it into a small upper, on a somewhat larger, lower part. Because of the sub-micron dimensions involved, good alignment between these is normally difficult to achieve. The present invention discloses a self-alignment process based on first laying down a mask that will determine the shape of the top part. Ion beam etching is then initiated, the ion beam being initially applied from one side only at an angle to the surface normal. During etching, all material on the near side of the mask gets etched but, on the far side, only material that is outside the mask's shadow gets removed so, depending on the beam's angle, the size of the lower part is controlled and the upper part is precisely centrally aligned above it.

Abstract:

The present invention pertains to methods of preserving fresh produce with a produce preservative which extends the shelf life of fresh produce, particularly cut fresh produce. The produce preservative preserves the texture, flavor, appearance, crispness, and color of the fresh produce, particularly the exposed surface of the fresh produce. The method comprises the following steps: providing a solution of produce preservative comprising: water, magnesium ions or zinc ions or tin ions; and ascorbate ions, or erythorbate ions; wherein the magnesium ion or zinc ions or tin ions and ascorbate ions are present in a mole ratio of preferably from 0. 2:1 to 8:1, more preferably from 0. 75:1 to 8:1, more preferably from 1:1 to 4:1, most preferably 1. 5:1 to 3:1, applying said produce preservative to the produce; applying said produce preservative to the produce.

International Classification:

G06F 17/18

US Classification:

702179, 702185

Abstract:

Systems and methods for detecting an interesting event in a data stream. More specifically, a monitoring system is configured to monitor a data stream and establish a sensitivity parameter based on sequences generated from values in a first portion of the data stream. A detector may be trained using the sensitivity parameter to detect the occurrence of an interesting event in the data stream.
