    摘要: Methods of forming integrated circuit substrates include forming first and second trenches having unequal widths in a semiconductor substrate and then depositing a first oxide layer at a first temperature into the first and second trenches. The first oxide layer has a thickness sufficient to completely fill the first trench but only partially fill the second trench, which is wider than the first trench. A step is also performed to selectively remove a portion of the first oxide layer from a bottom of the second trench. A second oxide layer is then deposited at a second temperature onto the bottom of the second trench. The second temperature is greater than the first temperature. For example, the first temperature may be in a range from about 300° C. to about 460° C. and the second temperature may be in a range from about 500° C. to about 600° C.

    摘要: A heat exchanger that can mechanically automatically control a level of cooling water according to heat generation of the fuel cell. The heat exchanger includes a housing having a cooling water inlet and an outlet connected to a fuel cell stack, a moving plate which moves reciprocally in the housing and discharges cooling water filled in the housing to the stack when it moves in a one direction and when it receives a steam pressure from the stack it moves in an opposite direction, and an elastic member that applies a force to the moving plate in the one direction. The heat exchanger can automatically maintain the level of cooling water despite a difference in heat generated between a full and a partial load operation of the fuel cell obviating complicated electronics such as a thermo-sensor, a valve, or a controller. Also, under a partial load, the exposure of flow channels to superheated steam is avoided, thereby extending the lifetime of the fuel cell.
