Title: Resin-sealed type semiconductor device
Inventor: SAKANE HIDEO
IPC: H01L21/56
Filed: 1981-06-18
Abstract: PURPOSE:To reduce the internal stress of a semiconductor device due to a thermal stress by sealing between the periphery of a semiconductor substrate and the substrate, thereby providing resin stopper for preventing the resin for forming a resin sealing layer from entering the gap between a semiconductor chip and the substrate. CONSTITUTION:A resin stopper 5 surrounds the periphery of a semiconductor substrate 11, bonds the periphery of the substrate 11 to a substrate 2, and prevents the sealing resin from entering the gap 4 between a semiconductor chip 1 and the substrate 2. This stopper 5 is performed by fixing the periphery of the substrate 11 by the use of an epoxy resin bonding sheet of a B stage. Since the stopper 5 prevents the resin for forming a resin sealing layer 3 from entering the gap 4 between the chip 1 and the substrate 2 in this manner, the internal stress due to the thermal stress based on the difference of thermal expansion coefficients between the material of the chip 1 and the resin for forming the layer 3 can be reduced.

IPC: C30B29/68
Filed: 1998-04-08
Abstract: PROBLEM TO BE SOLVED: To eliminate a defect on an interface, as seen in an Si/Ge strained superlattice, by combining one or more kinds of a single kind isotope so as to manufacture a thin-film element. SOLUTION: In a thin-film element, an Si substrate 1 for epitaxial growth is set on a substrate heater, a solid isotope Si<28> 11 is set on a first evaporation source cell, and a solid isotope Si<30> 21 is set on a second evaporation source cell. And then, under a predetermined condition, power of an electron beam is controlled so as to grow the solid isotope Si<28> 11 for 100 s at a rate of 1 Å/s, the solid isotope Si<30> 21 for about 5 s at a rate of 1 Å/s, and the solid isotope Si<30> 21 is grown by 1 atom layer. Hence, a structure is manufactured in which the solid isotope Si<30> 21 is caused to intrude regularly in the solid isotope Si<28> 11 layer by one atom layer. This arrangement makes it possible to readily obtain high light-emission efficiency and large mobility.

Title: Lead frame for plastic seal type semiconductor device
Inventor: YAMANAKA SEISAKU
IPC: H01L23/28
Filed: 1983-05-30
Abstract: PURPOSE:To obtain a lead frame having a function of high-sealing reliability by joining the lead frame and plastics through epoxy resin formed on both surfaces of the inner lead section of the lead frame in a plastic seal type IC. CONSTITUTION:Bondability among a sealing resin 12 and lead frames 11 is improved by forming thin layers consisting of epoxy resin coatings 14 on both surfaces of inner lead sections 13 as sealing sections with plastics 12 of the lead frames 11, and the intrusion of moisture into a package from a joining interface is prevented. The epoxy resin layers 14 are used in order to improve bond ability because the epoxy resin has excellent adhesive properties with epoxy resin containing a mold release as the sealing resin and a Fe-Ni alloy (such as 42 alloy) or a copper alloy employed as the lead frames. Since variance under the state of oxidation of the surfaces of the lead frames due to heating in chip bonding and wire bonding processes is eliminated and the properties of the surface are made constant at all times, a matching with the conditions of sealing is facilitated, and a leakage path is shortened particularly.

Title: Info1 signal detection circuit
IPC: H04L25/49
Filed: 1992-03-24
Abstract: PURPOSE:To reset a counter before it reaches a prescribed value so that the display output of a flip flop circuit can be continued and an INFO1 signal can be confirmed by setting the prescribed value to be outputted from the counter after the cancellation of reset by an AMI signal at the value larger than the arrival period of the AMI signal. CONSTITUTION:When the counter 10 is reset by the AMI signal, and after that, the reset is canceled, at this point of time, the counter 10 inputs a clock signal CLK and starts counting. In the case of the INFO1 signal, when the counter 10 and the F/F circuit 14 are reset by the arrival of the next AMI signal, and after that, the reset is canceled, the counter 10 counts the clock signal CLK. At that time, since the prescribed value of the counter 10 to cancel the display output is set larger than the period of the AMI signal, above- mentioned operation is repeated, and the output terminal Q of the F/F circuit 14 keeps an L level state, and a display device LED1 continues to be lighted, and the detection of the INFO1 signal can be confirmed.

Title: Recording medium
Inventor: KAWADE ISAAKI
IPC: G11B9/14
Filed: 1990-04-13
Abstract: PURPOSE:To allow the execution of recording and reproducing with good reproducibility and to simplify a tracking system by providing tracks changed in the thickness of recording layers having an electric memory effect on counter electrodes disposed opposite to a probe electrode. CONSTITUTION:The recording layers 1 form the tracks by partially existing in the counter electrodes 2 and the arrays of recording bits 4 are written on the recording layers 1 forming the tracks. The height of the probe electrode is set constant and the probe electrode is scanned in a Y direction shown in Fig. at the time of recording and reproducing of information. The recording layers themselves are as thin as <=100Angstrom  and, therefore, tunnel currents flow between the probe electrode and the counter electrodes without depending on the change in the thickness of the recording layers. The tunnel currents flowing in the probe electrode changes when the probe electrode deviates from above the recording layers onto the counter electrodes which are the non-recording surfaces. The probe electrode is so moved in an X direction or -X direction as to maintain the specified tunnel currents. The probe electrode is thus scanned on the recording layers in common use as the tracks.

Abstract: PURPOSE:To make the highest performance in a convergence system exhibitable in scanning a beam relatively on a sample face, by keeping the beam stationary but moving the sample alone, in regard to the scanning procedure of an electron beam, an ionic beam and suchlike to that sample. CONSTITUTION:A corpuscular beam B converged with a converging system 2 upon coming from a corpuscular source 1 is always left in a state of standing still while a sample 4 is arranged at a point where the corpuscular beam B connects an image and this sample gets moved. Doing so, the conventional deflection system need not be required any longer and thereby various optical problems caused by the deflection system itself do not happen at all, through which there is no binding requirements as to space and distance as the need to accommodate the deflection system so that no active distance l may be set at a most suitable distance for the converging system 2 and the corpuscular beam is efficiently converged to secure the highest performance, thus enabling it to obtain a super-minimal spot diameter by far smaller than ever before on the sample surface in high density.
