Abstract: A semiconductor memory device and the operating method thereof use a low pass voltage to boost a channel of unselected cell strings during a program operation, and boost the channel of the cell string by using the GIDL phenomenon, thereby reducing a disturbance influence on the memory cells connected to the unselected cell strings due to a high pass voltage.

Abstract: A manufacturing method of a fluid jetting apparatus, including: forming a heat driving part, a membrane, and a nozzle part; and forming a nozzle and jetting fluid chambers sequentially by using one nozzle plate, and assembling the heat driving part, the membrane, and the nozzle part, sequentially.

Abstract: A fluid jetting apparatus for a print head employed in an output apparatus, and a manufacturing process thereof. The process for manufacturing a fluid jetting apparatus includes: (1) forming a heat driving part having a sacrificial layer; (2) forming a membrane on the heat driving part which includes the sacrificial layer; (3) forming a nozzle part on the membrane; and (4) removing the sacrificial layer. The step (1) further includes: (i) forming an electrode and an exothermic body on a substrate; (ii) laminating a working fluid barrier on the electrode and the exothermic body, and forming a working fluid chamber in the working fluid barrier; (iii) forming a protective layer on the working fluid barrier, the electrode, and the exothermic body; (iv) forming a sacrificial layer within the working fluid chamber at a same height as the working fluid barrier.

Abstract: An electrostatic attraction type inkjetting apparatus including aboard having an ink chamber for receiving ink and a nozzle hole extending from the ink chamber to the extreme end of the board and thus open at the extreme end of the board; a membrane laminated on the board; a lower electrode received in the ink chamber; and an upper electrode disposed on the outer surface of the membrane. By the electrostatic attraction generated during an electric potential difference application between the upper and lower electrodes, the membrane is deformed inward to the ink chamber to press the ink of the ink chamber. Thus, the ink is jetted outward through the nozzle hole. Since the membrane and the driving section are integrally formed with each other, the manufacturing process becomes simpler, and electrostatic attraction generation, and ink discharge are performed efficiently.
