  • Publication number: 20240172395
    Abstract: A wick sheet for a vapor chamber includes a first main body surface, a second main body surface located opposite the first main body surface, a frame body section, and a plurality of land sections apart from each other within the frame body section. A vapor path through which a vapor of a working fluid travels is between the plurality of land sections. A liquid flow channel section that communicates with the vapor path and through which the working fluid in a liquid form travels is at the second main body surface side of at least one of the land sections. A bridge that couples the land sections to the frame body section or that couples the land sections to each other is included. The bridge is reduced in thickness from at least one of the first main body surface side and the second main body surface side.

  • Patent number: 7125730
    Abstract: In power supply and a semiconductor making apparatus and a semiconductor fabricating method using the same, an abnormality can be detected when an offset occurs in a part constituting a closed-loop system of high-frequency power supply or dc power supply for a semiconductor making apparatus. Power supply for receiving a power value setting signal to set strength of power and a power on/off instruction to set on or off of outputting of the power interrupts the supply of the power even in a state in which a subsequent power on/off instruction is on if a power sense signal according to a value obtained by sensing the power exceeds a predetermined value when the power on/off instruction is off.

  • Patent number: 7025895
    Abstract: A plasma processing apparatus and method are capable of performing etching with high precision without damaging the semiconductor wafer. The plasma processing apparatus has a plasma generation power supply for generating a plasma within a processing chamber; a high-frequency power supply for applying a high frequency wave to a sample stage installed within the processing chamber; and control means for controlling the plasma generation power supply or the high-frequency power supply based on parameter settings for an output intensity and an output mode for each process step. In this regard, when the process steps are switched, the control means compares parameters for a current process step with those for a next process step and then switches either the output intensities or the output modes before switching the output modes or the output intensities, respectively.
