  • Patent number: 6680256
    Abstract: A process for planarization of a flash memory cell is described. A first polysilicon pattern having a top is formed over a substrate. A high-density plasma (HDP) oxide layer is deposited on the first polysilicon pattern, wherein the HDP oxide layer has a protuberance over the first polysilicon pattern.

  • Patent number: 6521518
    Abstract: A method of eliminating weakness caused by high-density plasma (HDP) dielectric layer is provided. Before forming the HDP dielectric layer, a hot thermal oxide (HTO) layer is previously formed on the semiconductor substrate to serve as a buffer layer. The HTO layer eliminates the defect between the HDP dielectric layer and a cap nitride layer and releases the stress therebetween, and thereby preventing bit line leakage issue.

  • Patent number: 6496417
    Abstract: A method and an integrated circuit for performing a soft program after erase provides efficient convergence of over-erased floating gate memory cells disposed in bit lines. The soft program is applied to successive subject bit lines. The BLISP method includes selection of a selected bit line and applying the soft program to a subject bit line corresponding to the selected bit line. For integrated circuits having no defective bit lines, the subject bit lines comprise the selected bit lines. The BLISP method is adapted for low current consumption compared to bulk soft programming methods. In some embodiments, the integrated circuit includes defective bit lines. For these integrated circuits, the selection of the selected bit line includes indicating a bit line type corresponding to the selected bit line. The defective bit lines are logically replaced by redundant bit lines so that the soft program is applied to conforming selected bit lines and redundant bit lines corresponding to defective bit lines.

  • Patent number: 5870004
    Abstract: The frequency of an integrated oscillator is held constant by using temperature compensation to compensate for the component variations due to temperature variations. A voltage controlled oscillator, which has temperature dependent components, is compensated with a temperature dependent control voltage. The frequency of many kinds of oscillators such as a relaxation oscillators and ring oscillators can be held constant when the operating current is held constant. The operating current is often derived from a current source, which is a voltage to current converter with a current equal to the ratio of a control voltage to a resistance. Since semiconductor resistance has a positive temperature coefficient is used to obtain a temperature invariant current source. The positive temperature coefficient is obtained with the difference junction voltage of two forward-biased pn junction voltages. The magnitude can be controlled by junction areas of the two junctions. The magnitude can also be amplified.
