  • Publication number: 20160181267
    Abstract: A non-volatile memory cell, a NAND-type non-volatile memory, and a method of manufacturing the same are provided. The method of manufacturing the non-volatile memory cell includes the following steps. An insulating layer, a first conductive layer, an inter-gate insulating layer, a second conductive layer, and a hard mask layer are formed on a substrate in order. The hard mask layer, the second conductive layer, the inter-gate insulating layer, and the first conductive layer are patterned to form a stacked gate structure. The insulating layer on the substrate at two sides of the stacked gate structure is removed until the surface of the substrate is exposed. A portion of the substrate at two sides of the stacked gate structure is removed to form two recesses in the substrate, and each of the recesses is extended below the stacked gate structure. A source/drain region is formed in the substrate below the recesses.

  • Publication number: 20070206424
    Abstract: A method for erasing a non-volatile memory is provided. The non-volatile memory includes a first conductive type substrate, a second conductive type well disposed in the first conductive type substrate, a first conductive type well disposed on the second conductive type well, and a memory cell disposed on the first conductive type substrate. The memory cell includes a charge trapping layer and a gate. The erasing method includes the following steps. A first voltage is applied to the gate, a second voltage is applied to the first conductive type substrate, and the second conductive type well is floating. The second voltage is large enough to induce a substrate hot hole effect. The holes are injected into the charge trapping layer by applying the first voltage.

  • Publication number: 20030116762
    Abstract: This invention mainly provides a single-chip structure of silicon-germanium (SiGe) photodetectors and high-speed transistors. Primarily inserting a specified photo-absorbing layer in the photodetector, this device structure then provides the capability to absorb the light spectrum with an infrared wavelength, but also improves the overall optical absorption efficiency indeed. Then consider both the photodetector and the high-speed transistor have similar structures, therefore they can be well integrated on the same substrate by using the single-chip technology. Furthermore, one separated insulation layer will be adopted to isolate the photo-detecting zone and the high-speed transistor zone. Consequently, a single-chip structure of the SiGe photodetector and the high-speed transistor will be implemented.
