Title: Method of manufacturing a magnetic element
Inventor: VAN ZON JOANNES BAPTIST ADRIAN
IPC: G11B5/127
Filed: 2001-05-15
Granted: 2003-09-01
Abstract: In order to increase the information density on storage media the track width of a written magnetic pattern is made increasingly smaller. This requires write heads having appropriate flux guides. The method disclosed in this patent document provides such flux guides. The method includes the following steps: depositing a non-magnetic layer (3) of sufficient thickness; anisotropically etching the non-magnetic layer to form a steep wall of suitable dimensions at the required position of a flux guide; depositing a magnetic material to form a magnetic layer (9) on the wall in such a manner that the magnetic layer has a thickness corresponding to the required track width; removing undesired deposits of magnetic material but maintaining the magnetic layer on the wall; depositing an insulating material (19a) to cover the magnetic layer.

Inventor: SHIU TSAI-CHI
IPC: B29D28/00
Filed: 2001-05-16
Granted: 2002-07-01
Abstract: The present invention relates to a multi-color mesh belt extruder, in which the injection seat of the extruder is installed with a single feed inlet, and the feed shaft pipe in the extruder is installed with a plurality of feed inlet channels spaced at an equal angle. Each inlet channel is installed with a color opening which is installed with a color machine for providing a color stripe on the extruded mesh belt. The bottom of the feed shaft pipe is installed with a separation seat. The dividing plate of the separation seat is installed in the converge region of the inner mold seat and the outer mold seat which is mainly used for controlling the dissolution degree (such as gradation type or differentiation type) of each color material injected. Thus, the present invention can be used to produce a multi-colored product which is different from a conventional single colored product.

The first address transition detecting signal (psiATD1) controls refresh operations, and the second address transition detecting signal (psiATD2) controls read operations and write operations. When noise is generated, only refresh operations are carried out, so that the occurrence of an operating current can be limited effectively.

Title: Self-aligned contact doping for organic field-effect transistors
Inventor: KLAUK HAGEN
IPC: H01L21/425
Filed: 2002-04-04
Granted: 2003-09-01
Abstract: The invention relates to a method for doping electrically conductive organic compounds, to a method for fabricating organic field-effect transistors and to an organic field-effect transistor of simplified structure. According to the claimed method, a dopant, which can be activated by exposure using activation radiation, is introduced into an electrically conductive organic compound, and the electrically conductive organic compound is exposed using the activation radiation. The activation radiation triggers a chemical reaction, by which the dopant is irreversibly fixates in the electrically conductive organic compound. By using a suitable arrangement of the individual elements of a transistor, it is possible to realize a transistor structure which is significantly less expensive to fabricate than organic field-effect transistors which have hitherto been known. In this arrangement, a source contact (4), a drain contact (5) and a gate electrode (2) are arranged next to one another on a substrate (1). The gate electrode (2) is insulated by a gate dielectric (3), the arrangement being selected in such a way that a distance (11a, 11b), in which the organic semiconductor (6) is applied directly to the substrate (1), is formed between gate dielectric (3) and source or drain contact (4, 5). Back-surface exposure makes it possible to produce doped regions (8, 9) in which the organic semiconductor (6) has an increased electrical conductivity, while a low electrical conductivity of the organic semiconductor (6) is retained in the channel region (7) which has been influenced by the field of the gate electrode (2).

Title: Method for improving photoresist scum of an opening
Inventor: SU HUNG-WEN
IPC: H01L21/027
Filed: 2002-04-11
Granted: 2003-04-11
Abstract: The present invention discloses a method for improving photoresist scum of an opening. The method deposits an I-line photoresist covering on a dielectric layer and an opening, and filling up the opening after the opening formed in the dielectric layer. Then, a chemical mechanical polishing (CMP) step is performed on the I-line photoresist to remove the I-line photoresist located on the dielectric layer and leave the I-line photoresist in the opening. Because the I-line photoresist composed of polymers can block alkali, such as amide, from diffusing efficiently, and the I-line photoresist filling up the opening can protect the sidewalls of the opening, thereby preventing photoresist deposited subsequently from adhering to the sidewalls of the opening to avoid the alkali, such as amide, reacting with the photoresist in the opening and forming photoresist scum to pollute the opening. Therefore, the pollution of the opening caused by the photoresist scum can be improved efficiently, thereby obtaining the objects of increasing the processing reliability and yield.

Abstract: Systems are provided for the enhancement of the system BIOS for microprocessor-based devices. Before the end of a BIOS start-up procedure, the BIOS operation is diverted to a BIOS security authentication system which may be a portion of an enhanced system BIOS. The BIOS security authentication system establishes communication with an information module, if the information module is present. The information module is typically a removable or installable card, which may be unique to one or more users. Based upon an information exchange between the security authentication module and the information module, the security authentication module controllably allows or prevents the system BIOS start-up procedure to resume and finish. In a preferred embodiment, the security authentication module is used as a pre-boot authentication system, to prevent a microprocessor-based device from booting up, unless a valid authorized information module is present. In other preferred embodiments, an adaptive security authentication module interface is provided, to allow information exchange with a variety of information modules having one or more information formats. In alternate embodiments, information from the information exchange may be transferred to the main system BIOS (such as to provide system functions to the BIOS, or to provide identity information of the user, based upon the information module).
