Title: Plug fabricating method
Inventor: NAGAOKA KOJIRO
IPC: H01L21/3213
Filed: 1999-08-06
Granted: 2001-04-11
Abstract: A plug fabricating method, capable of fabricating a minute plug with a good configuration, reducing scum and simplifying the plug fabricating process, makes an inter-layer insulating film on a Si substrate and forms a contact hole in the inter-layer insulating film. A direct contact layer in form of a Ti/TiN film is formed on the inter-insulating film to also cover the bottom surface and the side wall of the contact hole. After a W film is formed on the entire surface in a deposition chamber, ClF3 gas exhibiting a strong reducing property is supplied as an etching gas into the deposition chamber, and the W film and the direct contact layer are partly removed by etch-back processing using bas etching by the ClF3 gas. As a result, a contact plug of W deposited on the direct contact layer as the base is formed inside the contact hole.

Granted: 2001-03-11
Abstract: A method of forming a memory storage in a dynamic random access memory (DRAM) process is provided, particularly the memory portion is formed in one time and the steps of the process could be reduced. In process, first, a substrate is provided in which a first inter-polysilicon dielectric layer and a bit line-embedded second inter-polysilicon dielectric layer are formed. A silicon nitride is formed on the second inter-polysilicon dielectric layer, followed by forming a polysilicon layer on the silicon nitride. A portion of the polysilicon layer is defined and etched back to form a spacer layer, and then a third inter-polysilicon dielectric layer is deposited on the polysilicon layer. The third inter-polysilicon dielectric layer is defined and etched to form a memory storage node. Finally, a memory device is formed by etching the third inter-polysilicon dielectric layer. According to the above, the claimed invention could avoid the issue of short junction breakdown and render the storage node and the contact connect directly to save one step of a polysilicon layer deposition and etching.

IPC: G06F21/00
Filed: 1999-11-26
Granted: 2001-09-01
Abstract: This invention is a kind of method for preventing BIOS from viruses infection. It uses the essential signal during the flash memory write period to generate system management interrupt (SMI). Therefore, it is able to disable viruses by using SMI handler routine of BIOS when BIOS stored in the flash memory has writing action. It first connects the essential signal that is sent out from the flash memory to SMI event source input connector of the computer chipsets to make chipsets generate corresponding SMI# to computer CPU. Therefore, when CPU receives SMI#, it is able to check if the flash memory where BIOS is in is written into by SMI handler routine of BIOS. It immediately disables writing when the is viruses invasion is detected.

Granted: 2002-01-21
Abstract: A fuel cell battery having an electrolyte, and a moving anode having anode material deposited on two sides of an electrically conductive substrates, which can be either a rotating anode disk, or a linearly moving anode, sandwiched between two air electrodes wherein the air electrodes each have at least one recharging portion and at least one discharging portion. The recharging portion of the air electrode is designed for optimum recharging and the discharging portion of the air electrode is designed for optimum discharging such that the fuel cell battery performs to its maximum ability. The recharging air electrode area can be larger than the discharging air electrode area for faster recharge times. The recharging air electrode can be operated at lower current densities to prevent anode densification, anode shape change and dendrite growth. Discharging the anode material on both sides of the anode increases the depth of the discharge and increases the battery's capacity. The anode movement assures the anode is intermittently discharged to reduce passivation and further increases the depth of discharge. The motion of the anode helps to insure uniform replating during recharging. Further, the movement of the anode stirs; the electrolyte assuring a uniform distribution of metal ions. As a result, the invention provides a metal/air Fuel Cell Battery with high energy density high power density and good rechargeability.
