A flash memory system includes a path selector to determine to write to a non-volatile memory, a volatile memory or both the non-volatile memory and the volatile memory when the flash memory system is to write data. A record is stored in the non-volatile memory which is updated the status of the non-volatile memory after each one or more writing operations. When the flash memory system is powered on after a power loss, it could be recovered to a command executed prior to the power loss or to any checkpoint prior to the power loss by using the record.

A method for treating waste gas containing PFC and/or HFC, comprising contacting a mixture of gas waste containing PFC and/or HFC, ozone, and water with an iron oxide catalyst at a temperature between 50 and 300° C. by gas-solid contact to perform an oxidation reaction for reducing the amount of PFC and/or HFC. An apparatus for treating waste gas containing PFC or HFC is also provided. The operational temperature in the present invention is much lower than the prior art, and thus provides lower energy consumption and little risk of fire. The present invention is suitable for the treatment of waste gas containing PFC and/or HFC, especially for the removal of perfluorocompounds from the waste gas generated by semiconductor and photoelectrical product manufacturing plants.
摘要:
A method of forming a through-silicon-via (TSV) opening includes forming a TSV opening through a substrate. A recast of a material of the substrate on sidewalls of the TSV opening is removed with a first chemical. The sidewalls of the TSV opening are cleaned with a second chemical by substantially removing a residue of the first chemical.
摘要:
The present disclosure involves a method of fabricating a light-emitting diode (LED) wafer. The method first determines a target surface morphology for the LED wafer. The target surface morphology yields a maximum light output for LEDs on the LED wafer. The LED wafer is etched to form a roughened wafer surface. Thereafter, using a laser scanning microscope, the method investigates an actual surface morphology of the LED wafer. Afterwards, if the actual surface morphology differs from the target surface morphology beyond an acceptable limit, the method repeats the etching step one or more times. The etching is repeated by adjusting one or more etching parameters.
