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 method of estimating a lifespan of a fuel cell including a cathode and an anode which contain catalysts and an electrolyte membrane interposed between the anode and the cathode. A cyclic potential with a voltage ranging from a low voltage to a voltage greater than oxidation voltages of the catalysts is applied between the anode and the cathode and fuel cell performance is measured initially and after a predetermined number of cycles. The lifespan of the fuel cell may estimated based on degradation of cell performance after the predetermined number of cycles, based on CV curves obtained during the cycling of the potential and/or a change in particle size of the catalysts after the predetermined number of cycles.
