    • The present invention provides a yeast cell comprising a nucleic acid functionally encoding a eukaryotic (e.g., mammalian) protein homologue of a subunit (Sec11p, Spc1p, Spc2p and/or Spc3p) of the yeast signal peptidase complex. The yeast cell of this invention can be, for example, of the genus Saccharomyces, Schizosaccharomyces, Pichia, Hansenula, Kluyveromyces and/or Yarrowia. Furthermore, the yeast cell can lack one or more functional subunits (Sec11p, Spc1p, Spc2p and/or Spc3p) of the yeast signal peptidase complex. The present invention further provides a method for producing a protein heterologous to a yeast cell comprising expressing, in the yeast cell of this invention, a nucleic acid functionally encoding the heterologous protein under conditions which permit the expression of the nucleic acid as a precursor protein having a signal peptide and processing of the precursor protein to a signal peptide-cleaved form of the protein. A method is also provided for obtaining increased production of a protein heterologous to a yeast cell comprising expressing, in the yeast cell of this invention, a nucleic acid functionally encoding the heterologous protein under conditions which permit the expression of the nucleic acid as a precursor protein having a signal peptide and processing of the precursor protein to a signal peptide-cleaved form of the protein. Additionally provided is a method for producing a yeast cell capable of increased production of a protein heterologous to the yeast cell, comprising introducing into the yeast cell (with or without one or more functional SPC subunits) a nucleic acid which functionally encodes one or more eukaryotic protein homologues of the signal peptidase complex under conditions permitting the expression of the nucleic acid as the protein homologues.

    • The present invention is a method of fabricating a self-aligned split gate of flash memory. Aligned layers are formed on predetermined source regions and predetermined drain regions in advance. Spacers are formed on the sidewalls of the aligned layers. An etching rate of the spacers is different from an etching rate of the aligned layers. Therefore, if misalignment occurs during the patterning process to form a split control gate layer, the spacers also can be left after the aligned layer is removed. The remaining spacers serves as a implant mask during the implantion for the sources and the drains formation, so that the sources and the drains are formed in the respective positions of the aligned layers by self-alignment.
    • 本发明是制造闪存的自对准分裂门的方法。 对准层预先在预定的源极区域和预定的漏极区域上形成。 间隔物形成在对准层的侧壁上。 间隔物的蚀刻速率与对准层的蚀刻速率不同。 因此,如果在形成分割控制栅极层的图案化工艺期间发生不对准,则在去除对准层之后也可以留下间隔物。 剩余的间隔物在用于源和漏极形成的植入期间用作植入物掩模,使得源和漏极通过自对准形成在对准层的相应位置。
