    摘要: A fabrication method for a nonvolatile memory with a shallow junction is described. A gate structure, comprising an electron-trapping layer and a conductive layer, is formed on a substrate. A doped spacer is formed on the sidewall of the gate structure. Buried bit lines are further formed in the substrate beside the gate structure. Thereafter, thermal process is conducted to diffuse the dopants from the doped spacer into the substrate adjacent to the buried bit lines.

    摘要: A silicon nitride read-only memory that prevents the antenna effect is described. The structure of the silicon nitride read-only memory includes a word-line, an electron-trapping layer and a metal protection layer. The word line covers the substrate. The electron-trapping layer is positioned between the word line and the substrate. The metal protection line covers the substrate and electrically connects the word line to a grounding doped region in the substrate. Moreover, the resistance of the metal protection line is higher than that of the word line. The charges generated during the manufacturing process are conducted to the substrate through the metal protection line. The resistance of the metal protection line is also higher than that of the word line. The metal protection line can be burnt out by a high current after the completion of the manufacturing process to ensure a normal operation for the read-only memory.

    摘要: A method is described for forming a non-volatile memory comprising dividing a substrate into at least a memory array area and a logic device area. An oxide/nitride/oxide (ONO) layer is firstly formed on the substrate, and a photoresist layer is formed on the ONO layer by bit line photo process, and a bit line ion implantation process is performed on the substrate to form the plurality of bit lines structure. Then, a first polysilicon layer is deposited to form a plurality of word lines by word line photo condition. The complementary metal-oxide-semiconductor (CMOS) ONO layer is used to store the charge and the ONO layer is only touched by the photoresist layer once. Furthermore, the separated adjust photo condition of the memory array area and the logic device area can create a safe oxide thickness to solve the problem of leakage path between bit lines to bit lines by using a self-aligned silicide process.

    摘要: An ultraviolet-programmable P-type Mask ROM is described. The threshold voltages of all memory cells are raised at first to make each memory cell to be in a first logic state, in which the channel is hard to switch on, in order to prevent a leakage current. After the bit lines and the word lines are formed, the Mask ROM is programmed by irradiating the substrate with UV light to inject electrons into the ONO layer under the openings to make the memory cells under the openings be in a second logic state.

A plurality of plugs are then formed in the coding windows.
