Abstract: An electron detector (100) for use in particle beam apparatus (104), providing particularly high acceptance of backscattered electrons (BSE). The electron detector (100) includes an electron multiplier (106) having an input surface (108) for capturing backscattered electrons. The electron detector includes a first electrode (112) deployed between the electron multiplier (106) and the specimen (102). The first electrode (112) is biased at a negative potential with respect to the specimen (102) so as to generate a first electric field for retarding low energy secondary electrons emitted by the specimen (102) from reaching the electron multiplier (106), and thereby enables passage of the high energy backscattered electrons (BSE) emitted by the specimen (102) towards the electron multiplier (106). The electron detector includes a second electrode (116) deployed between the electron multiplier (106) and the first electrode (112). The second electrode (116) is biased at a negative potential with respect to the input surface (108) and is spaced from the input surface (108) at a distance selected so as to generate a second electric field for substantially inverting the trajectories of Type A secondary electrons, released on impingement of Type A backscattered electrons thereon, the Type A secondary electrons having trajectories away from the input surface, towards the input surface such that the input surface collects the Type A secondary electrons.

Abstract: Improved processes for quantizing a set of mean-preserving Tone Transfer Functions (TTFs) for a multi-level halftoning system which minimize or at least significantly reduce the overall quantization error in the system as a function of a prespecified system halftone cell size, P, and the number of micro output levels, L y , supported by the multi-level halftoning system. The processes call for dividing the range of possible input contone representative intensity values into T subintervals, where            T=PL       y             ; determining the values of the centers of the T-subintervals; and quantizing each of the normalized continuous mean preserving TTFs as a function of the values of the centers of the T-subintervals. According to a preferred embodiment, the quantizing is performed such that the quantized TTFs approximate the normalized continuous mean preserving TTFs and ideally satisfy the criteria that the maximum quantization error between any quantized and unquantized TTF is minimized. Further aspects of the invention are directed to methods for determining threshold levels for assignment to threshold matrices, and methods for specifying look-up tables, either of which (the matrices and look-up tables) may be used for converting input contone representative intensity values into a predetermined number of available micro output levels for a multilevel halftone system having a predetermined halftone cell size.

Abstract: An inspection apparatus having a compact configuration is provided in a SQUID flux meter used for nondestructive inspection to make inspection for defects, corrosion, etc. of metal in a nondestructive and non-contact mode. A SQUID 1, comprising two Josephson junctions 3, a washer coil 4, shunt resistors 5, a damping resistor 6, and a feedback modulation coil 8, is formed of a superconducting thin film on a substrate 14. A magnetic field applying coil 9 is formed on the same substrate 14 with a superconducting thin film or a normal conducting metal thin film. The magnetic field applying coil 9, which is wound plural turns around the SQUID 1, applies a dc or ac magnetic field for inspection to a sample. The change in magnetic field produced by a defect in the sample is detected directly by the washer coil 4, by which the position and size of the defect are inspected. Since the magnetic field applying coil is integrated on the same substrate as that on which the SQUID is formed, an increase in the scale of the apparatus can be restrained, providing a simple construction.

Abstract: A printing device (10) is commanded to print a reference set of intensity values from almost white or highlight regions through almost dark or shadow regions. A measuring device (12) measures the actual outputted printer intensity levels from the printing device (10). An interpolator (14) interpolates the printer intensity levels into a best fit smooth curve plotted against the reference set of intensity levels which produces a non-linear function. A mapping means and converter (24a, 24b) calculate a set of fractional intensity values and densities which produce a linear function when mapped with the printer intensity levels. A dot area parameter calculator (28) calculates a set of dot parameters defining a configuration of a halftone dot required to fill an area within the halftone cell corresponding to each intensity level. For each position of each halftone cell, a measurement processor (30) determines a distance between a current scan position (a,b) and a nearest edge defined by the dot parameters. A gray value calculator (50) calculates a gray value for the current scan position based on the distance and angle to the nearest edge of the dot. The halftone dot is completed when a gray value is calculated for each position within the halftone cell. The gray values are stored in a look-up table (26). When a new image is to be printed, the intensity values are input (54) and the scan position is indexed (52) through all available scan positions to generate corresponding addresses in the look-up table (26), causing the corresponding gray values to be output serially in order for use by a laser diode controller (56) of a laser printer or analogous controllers in other types of printers.

Dambarless leadframe 191 is formed having leads 193 that are widened in the region near the package edge such that the interlead spacing between adjacent leads is less than a predetermined minimum distance. Lower and upper mold release films 67 and 65 are stretched over a plurality of die cavities formed in bottom and top mold chases 179 and 173. The release films can be further stretched into the die cavities by a vacuum. Leadframe strip assemblies containing the dambarless leadframes, each holding integrated circuit dies 189 are placed such that the integrated circuit dies are each centered over a bottom mold die cavity 63 and over the bottom mold release films 65. When the top and bottom mold chases are superimposed, the mold release films 67 and 65 are clamped together, and an interface is formed at the edges of the top and bottom mold cavities and between the leads of the dambarless leadframe. The mold compound is forced into the cavities by pressure. The interface between the top and bottom release films prevents the mold compound from forming mold flash between the leads of the dambarless leadframe. The dambarless leadframe includes a specific support tape 197 for the internal leads and a specialized open gate design.
