In a method of cleaning process residues formed on surfaces in a substrate processing chamber, a sacrificial substrate comprising a sacrificial material is placed in the chamber, a sputtering gas is introduced into the chamber, and the sputtering gas is energized to sputter the sacrificial material from the substrate. The sputtered sacrificial material reacts with residues on the chamber surfaces to clean them. In one version, the sacrificial substrate comprises a silicon-containing material that when sputtered deposits silicon on the chamber walls that reacts with and cleans fluorine-containing species that are left behind by a chamber cleaning process.

A split gate NAND flash memory structure is formed on a semiconductor substrate of a first conductivity type. The NAND structure comprises a first region of a second conductivity type and a second region of the second conductivity type in the substrate, spaced apart from the first region, thereby defining a channel region therebetween. A plurality of floating gates are spaced apart from one another and each is insulated from the channel region. A plurality of control gates are spaced apart from one another, with each control gate insulated from the channel region. Each of the control gate is between a pair of floating gates and is capacitively coupled to the pair of floating gates. A plurality of select gates are spaced apart from one another, with each select gate insulated from the channel region. Each select gate is between a pair of floating gates.
Printing Of Organic Conductive Polymers Containing Additives

International Classification:
H01B 1/04 H01B 1/12 B05D 5/12
US Classification:
252500, 252510, 427 961, 427122
Abstract:
Additives to organic conducting polymers are described which enhance adhesion and resolution of printed films while retaining adequate electrical conductivity. The conductive polymer films are useful in printing conductive portions of thin film transistors such as sources and drains. Additives include surfactants, second macromolecules, plasticizers, and excess sulfonic acids.

International Classification:
H01L 29/76
US Classification:
257296000
Abstract:
An integrated MIS capacitor has two substantially identical MIS capacitors. A first capacitor comprises a first region of a first conductivity type adjacent to a channel region of the first conductivity type in a semiconductor substrate. The semiconductor substrate has a second conductivity type. A gate electrode is insulated and spaced apart from the channel region of the first capacitor. The second capacitor is substantially identical to the first capacitor and is formed in the same semiconductor substrate. The gate electrode of the first capacitor is electrically connected to the first region of the second capacitor and the gate electrode of the second capacitor is electrically connected to the first region of the first capacitor. In this manner, the capacitors are connected in an anti-parallel configuration. A capacitor which has high capacitance densities, low process complexity, ambipolar operation, low voltage and temperature coefficient, low external parasitic resistance and capacitance and good matching characteristics for use in analog designs that can be integrated with existing semiconductor processes results.

Method For Batch File Printing And Related User Interface
KONICA MINOLTA SYSTEMS LABORATORY, INC. - Huntington Beach CA
International Classification:
G06F 3/12
US Classification:
358 115
Abstract:
A batch file printing method is described. A user opens a file using an application, and issues a print request. From the print dialog box, the user chooses to set printing preferences. The print preferences dialog box includes tabs for setting various printing references, and an additional batch file printing tab for selecting a number of files to be printed as the same batch using the same printing preferences. The batch file printing tab includes a file list box showing the files to be included in the batch and buttons allowing the user to add files to or remove files from the list. The selected files, along with the currently open file, are printed at once using the same printing preferences set by the user. The selected files may be in different folders, and may be different type of files.

Evolution of pandemic coronavirus outlines path from animals to humans
"Very much like the original SARS that jumped from bats to civets, or MERS that went from bats to dromedary camels, and then to humans, the progenitor of this pandemic coronavirus underwent evolutionary changes in its genetic material that enabled it to eventually infect humans," said Feng Gao, M.D.
