  • Publication number: 20210010157
    Abstract: A method for manufacturing a SiC single crystal reducing crystallinity degradation at a wafer central portion wherein a growth container surrounds a heat-insulating material with a top temperature measurement hole, a seed crystal substrate at an upper portion inside the container, and a silicon carbide raw material at a lower portion of the container and sublimated to grow a SiC single crystal on the seed crystal substrate. A center position hole deviates from a center position of the seed crystal substrate and moves to the periphery side of the center of the seed crystal substrate. A SiC single crystal substrate surface is tilted by a {0001} plane and used as the seed crystal substrate. The SiC single crystal grows with the seed crystal substrate directed to a normal vector of the seed crystal substrate basal plane parallel to the main surface and identical to the hole in a cross-sectional view.

  • Patent number: 10665286
    Abstract: In a control method, external data input to the pseudo static random access memory with a reference clock signal in a write operation are counted to generate a first count value. Data written to a dynamic memory array of the pseudo static random access memory with a built-in clock signal in the write operation are counted to generate a second count value. An initial cycle of the built-in clock signal is smaller than a cycle of the reference clock signal. The first count value is compared with the second count value. When the first count value is equal to the second count value, a write match signal is enabled. When the enabled write match signal is received, the write operation is converted from an asynchronous mode to a synchronous mode to adjust the cycle of the built-in clock signal to be equal to the cycle of the reference clock signal.

  • Patent number: 10643689
    Abstract: A control circuit and a control method for a pseudo static random access memory are provided. The control circuit counts a number of latch times of data based on an external clock to generate a first count value, counts a number of write times of the data based on an asynchronous column address strobe clock to generate a second count value, and compares the first count value and the second count value. The control circuit provides a column address strobe clock according to the asynchronous column address strobe clock in an asynchronous mode. At the time of a first occurrence of the first count value being equal to the second count value, the control circuit enters a write operation into a synchronous mode from the asynchronous mode to adjust a period of the asynchronous column address strobe clock to a period of the external clock.
