摘要： A raster scan lithography system is modified so that the duration of illumination (dose modulation) for particular pixels is varied to lie between the full on and full off normally used. For instance, three levels of pixel intensity are provided, 100%, 70% and 30% (in addition to off which is 0%). The 30% and 70% pixels are used along the edge of a feature so as to locate the edge when written in between the lines of the cartesian raster scan grid. Thus the edges of the feature are moved off the grid, without the need for multiple passes. This pixel dose modulation uses three preset delay lines determining dwell times for each pixel on a pixel-by-pixel basis, as defined by a two (or more) bit deep memory file associated with the pattern to be written. Additionally, the pixel center locations are directly moved off the grid by deflecting the beam as it scans certain pixels located along feature edges. The amount of deflection is controllably variable to achieve various edge locations. This deflection is used by itself or in combination with dose modulation, and is implemented by an electrostatic deflector in the beam lens for an E-beam system.

摘要： In electron beam lithography, a lithography system uses multiple microcolumns in an array to increase throughput for direct writing of semiconductor wafers. The mismatch between the microcolumn array and the semiconductor die periodicity is resolved by using only one microcolumn to scan each individual die. This is accomplished by assuring that the stage carrying the semiconductor wafer moves a total distance in each of the X and Y directions which is greater than the pitch between adjacent die. Hence each die is scanned by only a single microcolumn although at possibly different times during the total stage motion.

摘要： A system for extracting design information from a semiconductor integrated circuit (IC) is disclosed. The system includes a microscope and camera for capturing a composite image of the IC in the form of a video signal. Image capture occurs on a section-by-section basis in which a "snapshot" of each section is taken, the die-holding table stepped to a new section, and a snapshot of the new section obtained. This image capture operation continues until a composite image of the IC is obtained by successive capture of contiguous or partially overlapping images covering all of the different sections of the die. An image processor receives the video signal from the optical means and generates an abstract representation of the die in the form of lists of identifying features such as the size, type and relative location of all transistors, and the width, length and relative location of all of the metal interconnects to the IC. These lists are subsequently compared with reference library circuits by a computer to recognize individual circuit cells. Once all of the ciruit cells on the die have been recognized, the computer then generates a schematic netlist of the IC.

The ground plate is coupled to the base plate over the plurality of conductor pads with a gap between the base plate and the ground plate. Each of the plurality of conductor pads forms a beam blanker across the gap with the ground plate.

摘要： A method for a raster scan particle or light beam lithography system for writing in multiple passes interleaved in such a manner as to achieve a composite result nearly identical to normal single pass raster scan writing with overlapped spots. Multiple pass writing, achieved with little or no degradation or throughput or lithography quality, provides an ideal platform for implementation of known image averaging techniques to improve lithography quality. This technique is combined with the known writing technique of "Virtual Addressing" to improve resolution with little or no degradation of throughput.

摘要： A high density CMOS dynamic RAM cell comprising a transistor and capacitance means formed in an n-well is disclosed. The capacitance means includes a polysilicon plate member disposed above a p-type region formed in the n-well. A buried contact, extending from the plate member, pierces the p-type region and contacts the well. In addition to the capacitance associated with the plate member, p-type region and well, capacitance is obtained between the side walls of the n-type regions and p-type regions.
