Title: Formation of solder bump
Inventor: NAMEKAWA MASATOSHI
IPC: H05K3/34
Filed: 1991-02-26
Abstract: PURPOSE:To easily set solder balls on the circuit board of a plastic molded type semiconductor device. CONSTITUTION:After forming large pad electrodes having a large diameter and small pad electrodes having a small diameter on a circuit board, a masking member provided with large- and small-diameter holes respectively corresponding to the large- and small-pad electrodes is formed on the circuit board and, at the same time, cored large solder bumps are formed by distributing cored large solder balls on the circuit board, inserting the solder balls into the large- diameter holes, and heating the solder balls. Then coreless small solder balls are formed by distributing coreless small solder balls on the circuit board, inserting the solder balls into the small-diameter holes, and heating the solder balls. Since the solder balls are set in each recessed section when the solder balls are distributed on the circuit board, the need of the conventional troublesome work for manually putting the solder balls in the recessed sections one by one can be eliminated.

Abstract: PROBLEM TO BE SOLVED: To make it possible to optimally correct error with an irreducible minimum number of interleaves at every sector. SOLUTION: A controller 18 sets N of an optimum number of interleaves according to a sector number at a medium access time.

Abstract: PURPOSE: To increase the capacity of a MOS transistor as a capacitor by successively forming layers of an insulating material and conductive material by specifying plugs each of which has an upper surface and at least two side sections after the MOS transistor is formed on the surface of a substrate. CONSTITUTION: After a step for forming a MOS transistor on the surface of a substrate 10 is executed, part of the source/drain area of the transistor is exposed by forming a masking layer 56. Then, after tungsten plugs 62 and 64 are formed, the layer 56 is removed and a conformal layer of an insulating material 66 and a conductive material 68 are formed on the plugs 62 and 64, the transistor, and a separation trench 48. In addition, a planar layer 69 of an insulating material is formed on the conformal layer and interconnection patterns 76 and 78 are formed in the source/drain area and between peripheral circuits.

While the light transmission bodies 1 and 4 do not contact each other, the light from a semiconductor laser 6 is reflected totally by the light output surface of the light transmission plate 1 to generate a high-level switching signal M through a photosensor 9 and a comparator 10. While the light transmission bodies 1 and 4 contact each other, the laser light is transmitted through the light transmission plates 1 and 4 and diffused by a diffusion plate 5 to output a low-level switching signal M from the comparator 10. Further, it can be confirmed whether the switch or a device is faulty by checking whether or not there is the reflected light from the diffusion plate 5 after the light transmission plate 4 is put in pressing operation.

Filed: 1996-02-19
Abstract: PROBLEM TO BE SOLVED: To improve sensitivity by reducing the influence of reception sensitivity drop caused by a vibrator by setting the fixing position of the vibrator near a short-circuiting point away from a feeding point. SOLUTION: Power is supplied from one corner part A-A' where conductor panels 1 and 2 are confronted, other corner parts B-B' and C-C' are short- circuited by a conductor 4, and a vibrator 5 is arranged near the corner part C-C'. Therefore, the arranging position of the vibrator 5 is set near the corner part C-C' most separated from the feeding point A-A', and that corner part C-C' becomes the point of short-circuiting due to the conductor 4. Therefore, even when the upside conductor panel 1 is electrostatically coupled and short- circuited in high frequency menner by generating stray capacity in the gap, the influence upon an effective antenna loop opening area is reduced.
