  • Publication number: 20240110970
    Abstract: Main cells that constitute a semiconductor element having a trench gate structure include first cells, and second cells having a structure in which gate insulating films are more easily broken by energization than those in the first cells, and the number of which is smaller than that of the first cells. At a time of driving the semiconductor element, a common gate drive voltage is applied to gate electrodes of the first cells and the second cells. An electrical characteristic is measured to detect failure of the second cells due to energization at the time of driving. The gate electrodes of the failed second cells are electrically isolated from the gate electrodes of the first cells so that the gate drive voltage is not applied to the failed second cells. The failure of the first cells is predicted based on the failure of the second cells.

    Abstract: The photosensitive region includes a first impurity region and a second impurity region having a higher impurity concentration than that of the first impurity region. The photosensitive region includes one end positioned away from the transfer section in the second direction and another end positioned closer to the transfer section in the second direction. A shape of the second impurity region in plan view is line-symmetric with respect to a center line of the photosensitive region along the second direction. A width of the second impurity region in the first direction increases in a transfer direction from the one end to the other end. An increase rate of the width of the second impurity region in each of sections, obtained by dividing the photosensitive region into n sections in the second direction, becomes gradually higher in the transfer direction. Here, n is an integer of two or more.
