The claimed lighter is used for kindling a fire and could be used for lighting gas stoves, fireplaces, gas lamps, cigarettes, cigars and candles. As the ability to access these markets is related to the rating of the assets, the model simulates rating movements over time and uses historical funding information of like assets to make estimates of future funding needs. The gate electrode layer and the gate lead line are electrically connected with each other by way of a resistor made of polysilicon containing an impurity, and an impurity concentration in polysilicon which forms the resistor is lower than an impurity concentration in polysilicon which forms the gate electrode layer.
