  • Publication number: 20080043543
    Abstract: A method of manufacturing, programming and reading a non-volatile memory is provided. First, a to-be-coded memory having a plurality of to-be-coded cells arranged in a array is provided. Next, an implanting resist layer is formed on the to-be-coded memory. Then, a mask is disposed on the to-be-coded memory, wherein the number of the partial to-be-coded cells under the openings of the mask is less than the number of remaining to-be-coded cells. Afterwards, a patterned implanting resist layer is formed according to the mask. Next, the exposed to-be-coded cells are ion-implanted to define a plurality of first cells and second cells, wherein each first cell and each second cell record a second bit state and a first bit state respectively. Then, the to-be-coded memory is inversely defined, such that the first cells and the second cells record the first bit state and the second bit state respectively.

  • Patent number: 6996459
    Abstract: To prevent a furnace in a semiconductor process from temperature and gas excursion, a paddle and spike thermal couples arranged on the sidewall of the tube and adjacent to the heater, respectively, are connected to a temperature controller to regulate the heater, and a mass controller adjusts the gas flow injected to the tube. In the method, the spike thermal couple, peddle thermal couple and zero point of the mass flow controller are checked to maintain within a first and second temperature ranges and a first gas flow speed range, respectively, and after wafers are loaded and temperature is ramped up, the peddle thermal couple and mass flow controller are checked again to maintain within a third temperature range and second gas flow speed range.
