摘要： A flash memory device and a method of programming the same include a memory cell array, a pass/fail check circuit and a control logic circuit. The memory cell array includes multiple memory cells arranged in rows and columns. The pass/fail check circuit verifies whether data bits selected by a column address during a column scan operation have program data values. The control logic circuit detects fail data bits from the selected data bits and stores the column address in response to the verification result of the pass/fail check circuit. The control logic circuit also compares a number of the fail data bits with a reference value and controls generation of the column address according to the comparison result.

摘要： Provided are a lift pin capable of preventing aluminum from depositing on the lift pin when depositing a metallic layer on a wafer through chemical vapor deposition. a system using the lift pin, and a method of manufacturing the same. The lift pin is made of stainless steel and is oxidized at a predetermined temperature for a predetermined time, such that the lift pin is not deposited with aluminum during a CVD process. Since the CVD vacuum processing chamber utilizes the heater and the lift pin which are made of oxidized SUS material, aluminum does not deposit on the heater and the lift. Therefore, when the lift pin is lowered, the lift pin is not lowered by its own weight, thereby preventing a wafer from being broken. Also, the lift pin is prevented from being ruptured by a robot moving in and out of an opening of the CVD vacuum processing chamber.
