Title: Compound ceramic capacitor
Inventor: HARADA JIRO

Filed: 1990-03-22
Abstract: PURPOSE:To enable the title compound ceramic capacitor having enhanced characteristics such as high capacity and high withstanding voltage to be manufactured easily at low cost by a method wherein sheets are junctioned with outer electrodes making them mutually conductive through the intermediary of thermosetting conductive synthetic resin. CONSTITUTION:Multiple chip type laminated ceramic capacitors 1(1A-1C) are lamination-bonded through the intermediary of a bonding agent 2. Next, metallic sheets 6 are abutted with one another through the intermediary of a thermosetting conductive synthetic resin 5 to make the outer electrodes 4(4A-4C) of the formed compound body 3 conductive so that the metallic sheets 6 may be electrically heat- treated at the setting temperature (100-250 deg.C) of the resin 5 for 30 minutes to be junctioned with the outer electrodes 4. Through these procedures, the metallic sheets 6 can be junctioned with the electrodes 4 through the intermediary of the resin 5 without resorting to the soldering step to absorb the thermal shock thereby enabling the deterioration in performance and the development of defective products (decrease in the yield) due to the thermal shock to be avoided. On the other hand, the bonding work of the metallic sheets 6 can be facilitated without using a high temperature solder simultaneously enabling the manufacture to be automated while enhancing the characteristics of the title capacitor due to the elimination of the soldering step.

IPC: H01L21/265
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To provide an annealing method for GaAs substrate having good quality capable of easily forming and removing a protection film and restricting the evaporation of As. SOLUTION: Ion is implanted on the surface of a GaAs substrate 1 thereby forming an impurity layer 2, and B2 O3 film 3 is formed by covering the surface of the layer 2. GaAs substrate 1, on which the B2 O3 film 3 is provided, is inserted into a holder. At this time, a gap 10 (about 200μm) is produced between the top of the GaAs substrate 1 and a lid plate 9. In this state, it is supplied to annealing equipment and heat treatment is performed at 950 deg.C. Then, the gap 10 becomes an insulating material and the whole surface of the substrate is heated uniformly. And B2 O3 does not react to Gs and As, so that As pull-out or dispersion to B2 O3 film does not occur and thus annealing can be performed. Also during annealing, B2 O3 has been liquefied so that no stress is given to the GaAs substrate. In addition, after annealing, B2 O3 film 3 can be easily removed by washing with water.
