Abstract:
PROBLEM TO BE SOLVED: To provide an E beam system for storing calibration data and using a hyper-parallel array of electron sources assembled by an integrated circuit technology as well as a system for each beam to control individual beams, by using the calibration data. SOLUTION: The E beam system stores the calibration data by using a flash EPROM and generates one set of super-parallel beams with a scale of 1,000 beams by receiving on/off signals directed by an address system of a memory array with each electron source mounted on the memory array as a geometrical array to trace a memory array structure.

Abstract:
PROBLEM TO BE SOLVED: To provide equipment for positioning a wafer inside an exposure device. SOLUTION: The equipment comprises a holder 124 constituted to hold a wafer 126 (having a plurality of positioning mark), a rough positioning device, and a fine positioning device having more accuracy than the rough positioning device. The fine positioning device has a plurality of photodetectors 122. Each photodetector is arranged in order to detect a corresponding positioning mark on the wafer. A positioning processor 120 is connected to the plurality of photodetector and holder, and controls them. The plurality of photodetectors are controlled by the positioning processor, and detect the plurality of positioning mark in parallel operation. Further, the positioning processor processes signals from the plurality of photodetector in parallel operation at a time. COPYRIGHT: (C)2005,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To provide a system for effectively separating the reactivity of a gaseous phase reactant and the chemical reaction of a wafer surface. SOLUTION: A processing system, based on previously loaded plasma, is provided with a preliminary reaction plasma processing chamber, a power source connected to the preliminary reaction plasma processing chamber so as to drive the chamber and a wafer plasma processing chamber connected to the preliminary reaction plasma processing chamber through fluid. The preliminary reaction plasma processing chamber is constituted so as to generate reaction radicals, by subjecting to chemical reaction based on the plasma of a reaction substance. The wafer plasma processing chamber is constituted so as to allow reaction radicals to react with the seeds on the surface of a wafer arranged in the wafer plasma processing chamber. Another example includes a method for processing a wafer in a plasma environment, pre-loading a reactive gaseous flow and previously preventing the erosion of a wafer mask or an etching stop layer.

Abstract:
PROBLEM TO BE SOLVED: To provide a structure and a method for an EEPROM device, having a high performance logic (such as complementary metal-oxide semiconductor(CMOS), for example), or EEPROM device, being integrated with a nonvolatile random access memory(NVRAM). SOLUTION: The EEPROM device is provided with mutually self-matched floating gate and program gate. During programming, electronic tunneling occurs between the floating gate and the program gate.
Abstract:
A method of forming a wiring structure for an integrated circuit includes the steps of forming a plurality of features (16) in a layer of dielectric material (13), and forming spacers (20) on sidewalls (16s) of the features. Conductors (25) are then formed in the features, being separated from the sidewalls by the spacers. The spacers are then removed, forming air gaps (40) at the sidewalls so that the conductors are separated from the sidewalls by the air gaps. Dielectric layers (42, 12) above and below the conductors may be low-k dielectrics having a dielectric constant less than that of the dielectric between the conductors. A cross-section of each of the conductors (25) has a bottom in contact with a low-k dielectric layer (12), a top in contact with another low-k dielectric (42), and sides in contact only with the air gaps (40). The air gaps serve to reduce the intralevel capacitance.
Abstract:
A patterned buried insulator is formed beneath the source and drain by forming a mask over the body area and implanting a dose of n or p type ions in the areas where the source and drains will be formed, then etching the STI and etching out the implanted area. A light oxidation is followed by a conformal oxide deposition in the STI and also in the etched area, thereby forming the buried oxide only where desired.
