摘要:
A method is described for using computer aided design data for contact holes in a background, such as an opaque background or a phase shifting background, to generate computer aided design data for fabricating a mask an outrigger pattern. The outrigger pattern mask has contact holes surrounded by a first border of opaque material and the first border of opaque material surrounded by a third border of attenuating or 100% transmittance phase shifting material. The third border of attenuating or 100% transmittance phase shifting material is surrounded by opaque material. The design data for the contact hole pattern, a background pattern, a first correction pattern, and a second correction pattern are combined in a computer processor to generate final data. The final data is used to fabricate the mask.

A method is disclosed for employing direct electron beam writing in the lithography used for forming step-profiles in semiconductor devices. The number of steps in the profiles are not limited. An electron beam sensitive resist is formed over a substrate. The resist is then exposed to a scanning electron beam having precise information, including proximity effect correction data, to directly form stair-case-like openings in the resist. The highly accurately dimensioned step-profiles are then transferred into the underlying layers by performing appropriate etchings. The resulting structures are shown to be especially suitable for forming damascene interconnects for submicron technologies.

A touch-control mouse provides rapid and accurate control of the positioning of a cursor on a computer display screen, and includes a laminated touch-control film assembly, an aluminum supporting board, a press button switch set, a signal processing circuit board, and a dust-protective hanging case. Drawing using a finger on x-axis and y-axis resistance planes of the laminated touch-control film assembly results in variable potential value for x, y coordinates. The value of potential variation is calculated through a single-chip microprocessor to indicate relative direction, speed and amount of displacement on x, y coordinates. The signal of the relative direction, speed and amount of displacement is further is further sent by the single-chip microprocessor through a standard RS-232 connector to one of the serial communications ports of a PC to rapidly and accurately control the positioning of the cursor on the computer display screen.

摘要:
A method for fabricating a high-density array of crown capacitors with increased capacitance while reducing process damage to the bottom electrodes is achieved. The process is particularly useful for crown capacitors for future DRAM circuits with minimum feature sizes of 0.18 micrometer or less. A conformal conducting layer is deposited over trenches in an interlevel dielectric (ILD) layer, and is polished back to form capacitor bottom electrodes. A novel photoresist mask and etching are then used to pattern the ILD layer to provide a protective interlevel dielectric structure between capacitors. The protective structures prevent damage to the bottom electrodes during subsequent processing. The etching also exposes portions of the outer surface of bottom electrodes for increased capacitance (>50%). In a first embodiment the ILD structure is formed between pairs of adjacent bottom electrodes, and in a second embodiment the ILD structure is formed between four adjacent bottom electrodes.

摘要:
A mask and method of forming a pattern on an integrated circuit wafer having regions of dense line/space patterns and regions of isolated lines or widely spaced line/space patterns. The mask uses a binary mask pattern to form the dense line/space region and an attenuating phase shifting mask pattern to form the isolated line or widely spaced line/space region. Scattering bars are used in the widely spaced line/space region of the mask to improve depth of focus. The method uses the mask in a projection exposure system to expose a layer of photosensitive dielectric on an integrated circuit wafer.
