Patent number: 10418339Abstract: The present disclosure relates to a method for bonding semiconductor components. A semiconductor component comprising microbumps on a planar bonding surface is prepared for bonding by applying a photosensitive polymer layer on the bonding surface. The average thickness of the initial polymer layer in between the microbumps is similar to the average height of the microbumps. In a lithography process, the polymer is removed from the upper surface of the microbumps and from areas around the microbumps. The polymer is heated to a temperature at which the polymer flows, resulting in a polymer layer that closely adjoins the microbumps, without exceeding the microbump height. The closely adjoining polymer layer may have a degree of planarity substantially similar to a planarized layer.Type: GrantFiled: June 27, 2018Date of Patent: September 17, 2019Assignee: IMEC VZWInventors: Fabrice Duval, Fumihiro Inoue

Patent number: 10355594Abstract: A DC-DC converter, which allows a current to pass through an inductor and rectifies the current through the inductor to convert an input direct current voltage supplied from a direct current power unit into a direct current voltage at a different potential and output the direct current voltage, includes a switching control circuit performing peak-current control procedures including turning on the switching element when the converted direct current voltage drops to a predetermined potential and turning off the switching element when the current through the inductor reaches a predetermined value. The converter includes a copied-current generating circuit generating a current proportional to the output current. The switching control circuit turns off the switching element when the circuit detects that the current through the inductor reaches a predetermined value with reference to a combined current of the copied current generated at the copied-current generating circuit and a predetermined reference current.Type: GrantFiled: October 24, 2016Date of Patent: July 16, 2019Assignee: MITSUMI ELECTRIC CO., LTD.Inventors: Heisuke Nakashima, Kenji Mitsuhira, Fumihiro Inoue
