  • Patent number: 9143117
    Abstract: A soft error protection device includes a soft error resilient latch (SERL) and a latch coupled to a detection device and receiving a soft error pulse and a clock (CLK) signal respectively outputted by an electronic element and a CLK generator. The SERL delays the soft error pulse. In the period of a negative level of the CLK signal, the SERL stores the delayed soft error pulse corresponding to the negative level and used as a first detection data. Meanwhile, the latch stores the soft error pulse as a second detection data. The detection device receives the CLK signal, the first and second detection datum, and compares the first and second detection datum to send out a detection signal when the CLK signal rises from the negative level to a positive level.

  • Publication number: 20140272704
    Abstract: Among other things, one or more techniques and systems for performing a spin coating process associated with a wafer and for controlling thickness of a photoresist during the spin coating process are provided. In particular, a thickening phase is performed during the spin coating process in order to increase a thickness of the photoresist. For example, air temperature of down flow air, flow speed of the down flow air, and heat temperature of heat supplied towards the wafer are increased during the thickening phase. The increase in down flow air and heat increase a vaporization factor of the photoresist, which results in an increase in viscosity and thickness of the photoresist. In this way, the wafer can be rotated at relatively lower speeds, while still attaining a desired thickness. Lowering rotational speed of wafers allows for relatively larger wafers to be stably rotated.
