A method of fabricating a flash memory device includes depositing and etching an insulating layer on a substrate having STI structures, depositing a first polysilicon layer over the insulating layer and the substrate, etching the first polysilicon layer to form floating gates and removing the insulating layer. The method also includes forming a first photoresist pattern, performing a first ion implantation using the first photoresist pattern to form first source/drain regions in the substrate and adjacent to the floating gate, removing the first photoresist pattern, depositing an ONO layer on the resulting structure, depositing a second polysilicon layer over the ONO layer, and etching the second polysilicon layer to form a control gate and at least one select gate. The method concludes by forming a second photoresist pattern and performing a second ion implantation using the second photoresist pattern to form second source/drain regions in the substrate and adjacent to the select gate.
摘要:
The present invention relates to a steam generator and a washing machine therewith. The present invention provides a steam generator including a water chamber for holding water, the water chamber having a heater mounted thereto for heating the water, a steam chamber for holding steam generated as the water chamber, and steam water is heated, a water supply line for supplying the water to the water chamber, and a steam discharge line for discharging steam from the steam chamber, wherein the water chamber has a vertical direction length (a vertical length) relatively greater than a horizontal direction length (a horizontal length); and a washing machine therewith.

A DTV transmitter includes a pre-processor expanding original enhanced data, a data formatter generating enhanced data packets including the expanded enhanced data and inserting known data place holders into the data packets, a multiplexer multiplexing the enhanced data packets with main data packets including main data, and an RS encoder adding systematic RS parity data to each main data packet and adding non-systematic RS parity data holders to each enhanced data packet. It further includes a data interleaver interleaving the RS-coded data packets, a known data generator generating know data symbols, a converter converting the interleaved data packet into symbols, and a symbol processor processing the converted symbols. The symbol processor removes symbols representing the null data, encodes symbols representing the original enhanced data at a rate of N/M, and replaces symbols representing the know data place holders with known data symbols.
摘要:
A self-magnetized motor includes a stator adapted to rotate by electromagnetic interaction with a rotator, a plurality of slot teeth formed on and surrounding a through-hole of the stator, and an excitation pole adjacent at least one slot tooth having fewer projections than remaining ones of the slot teeth. The projections are formed on ends of the slot teeth facing the through-hole of the stator. According to one non-limiting embodiment, the excitation pole may be formed between two slot teeth having fewer projections.
摘要:
A device and/or method which detects a seed layer and a device and/or method of forming layers on a semiconductor device. The device which forms layers on the semiconductor device may include a metal layer forming unit (which forms a metal layer on a wafer), a copper seed layer forming unit (which forms a copper seed layer on the metal layer), a wafer alignment device (which includes a wafer alignment unit which aligns the wafer to a predetermined position), a copper seed layer detecting unit (which is positioned above the wafer alignment unit to detect the copper seed layer formed on the wafer), and a plating unit (which forms a copper interconnection layer on the copper seed layer).

A vacuum cleaner is disclosed. The vacuum cleaner comprises a cleaner body, a cyclonic chamber comprising a primary cyclone and at least one secondary cyclone disposed around the primary cyclone, a flow passage guide for guiding the airflow discharged from the primary cyclone to a secondary airflow inlet of the secondary cyclone, a first conduit for fludically connecting a nozzle section defining a suction opening to a primary airflow inlet of the primary cyclone, a suction source having an suction source inlet and an suction source outlet, and a second conduit for fludically connecting a secondary airflow outlet to the suction source inlet of the suction source. Accordingly, it is possible to achieve a low flow resistance by virtue of the flow passage guide and an enhanced dust collecting performance by virtue of a sealing effect of the sealing member.
