  • Patent number: 7001697
    Abstract: A photomask for use in photolithography has substrate, a main pattern at one side of the substrate, and a transparency-adjusting layer at the other side of the substrate. The transparency-adjusting layer has a characteristic that allows it to change the intensity of the illumination incident on the main pattern during the exposure process accordingly. In manufacturing the photomask, a first exposure process is carried out on a wafer using just the substrate and main pattern. The critical dimensions of elements of the pattern formed on the wafer as a result of the first exposure process are measured. Differences between these critical dimensions and a reference critical dimension are then used in designing a layout of the transparency-adjusting layer in which the characteristic of the layer is varied to compensate for such differences.

  • Patent number: 6999160
    Abstract: In a method of optimizing a shape of an aperture, an effective light source is divided into a plurality of minute areas having same shape and size. One point light source is provided at a center of each of the divided minute areas. A normalized image light intensity slope on a wafer is obtained in consideration of a focus variation of a projection aligner for a plurality of patterns at each of the point light sources. The normalized image light intensity slope of a light intensity is used as an index. The image light intensity slope is related to an exposure amount variation of the projection aligner by one dimensional function. A common opening is selected for the shape of the aperture that is optimized for each of the patterns. The common opening is made into an optimum shape of the aperture for the patterns.

  • Patent number: 6998902
    Abstract: A bandgap reference voltage circuit includes a constant-current circuit, a reference voltage output circuit generating a reference voltage according to the constant current, a power supply voltage detection circuit, and a start-up output circuit. The start-up output circuit supplies a starting potential to the constant-current circuit until the power supply voltage detection circuit detects that the power supply has reached a voltage sufficient for the constant-current circuit to maintain operation. The power supply voltage detection circuit has elements analogous to the elements in the constant-current circuit that determine this voltage, so start-up operation can occur and end reliably. The start-up output circuit includes a low-impedance path from the power supply to a node controlling supply of the starting potential, so power-supply noise does not trigger unwanted output of the starting potential after start-up operation has ended.

  • Patent number: 6998309
    Abstract: A method of manufacturing a non-volatile semiconductor memory device begins by forming a dielectric layer pattern having an ONO composition on a substrate. A polysilicon layer is formed on the substrate including over the dielectric layer pattern. The polysilicon layer is patterned to form a split polysilicon layer pattern that exposes part of the dielectric layer pattern. The exposed dielectric layer is etched, and then impurities are implanted into portions of the substrate using the split polysilicon layer pattern as a mask to thereby form a source region having a vertical profile in the substrate.

  • Patent number: 6999336
    Abstract: A memory cell array includes ferroelectric memory cells arranged in m rows and n columns, bit lines provided along a row direction, and word lines and plate line provided along a column direction. The word lines are provided side by side so as to intersect each other at the border between the fourth row and fifth row. The arrangement allows the connecting of four ferroelectric memory cells to the same plate line and the same word line. Since the number of ferroelectric memory cells to be accessed simultaneously will be one-half the number of memory cells provided in one row, unnecessary access to the ferroelectric memory cells is reduced, to suppress deterioration of the ferroelectric memory cells. The word lines may instead intersect each other between the second and third lines, so that two ferroelectric memory cells are connected to the same plate and word lines.

  • Patent number: 6995049
    Abstract: In a method for forming a silicon-on-insulator FET having a contact that provides a fixed potential to a substrate, the substrate-biasing between the SOI transistor and the silicon substrate is performed via a plug. As a result, a contact hole for the substrate-biasing does not need to pass through the insulating layer, the silicon layer, and the interlayer insulating layer of the structure. Therefore, the interlayer insulating layer can be made to have shallow depth. Ions can thus be implanted to the surface of the substrate via the contact hole for substrate-biasing. The contact hole for substrate-biasing can be formed without causing an opening fault.

The apparatus includes a container, like a FOUP, for containing substrates, at least one processing chamber where the substrates are processed, a substrate transferring module including a substrate transfer chamber and at least one load port for supporting a container, and a contamination controlling system for the substrate transfer chamber. The contamination controlling system includes a purge gas supply inlet connected to the substrate transfer chamber, and a gas circulating tube for recycling the purging gas to circulate through the chamber. The substrate transfer chamber is purged using the purging gas to remove moisture and contaminating materials from the substrate transfer chamber. The formation of particles on the substrate otherwise caused by a reaction between the moisture and contaminating materials while the substrate is standing by in the container can be prevented.

  • Patent number: 6991993
    Abstract: The present invention provides a method of fabricating trench isolation structures of a semiconductor device. A conformal trench filler insulation layer is formed to fill wide and narrow trenches in a substrate. A portion of the trench filler insulation layer filling the wide trench is then removed. Next, a trench protection layer is formed on the trench filler insulation layer. The resultant structure is planarized to leave the trench protection layer over the wide width trench. Another planarization process is then carried out using the etch mask pattern and the remaining trench protection layer as a planarization stopper. Accordingly, the device isolation layer will attain a uniform planarity irrespective of the various widths of the trenches.

  • Patent number: 6989558
    Abstract: In a field effect transistor having an active region defined by a device isolation region, and a gate electrode formed over the active region, in the lateral direction of the gate electrode, the source and drain formed in the active region is narrower than the active region at least at the parts proximate to each other to create a rounding region for allowing an additional current to flow through the rounding region. This increases the on-current, with almost no increase in the off-current. The operation speed is thereby increased, without increase in the power consumption during stand-by.

  • Patent number: 6987687
    Abstract: A ferroelectric memory of a 1T/1C type has a pair of dummy memory cells DMC2n?1 and DMC2n. Different information have been stored in the dummy memory cells. When the information is read, out from each dummy memory cell, a potential Va is developed on a bit line BL2n?1, a potential Vb is developed on an adjacent bit line BL2n. Since the bit lines BL2n?1 and BL2n have the same capacitance, a potential Vave of each bit line which was short-circuited by a short-circuit portion s2a is equal to a just intermediate value (Va+Vb)/2 of the potentials Va and Vb. The potential Vave is applied to sense amplifiers SAn?1 and SAn as a reference potential.
