摘要:
Pour réduire la capacité d'un module électronique comprenant un composant actif (1) soudé sur une embase (2), et ainsi augmenter sa fréquence de coupure, le procédé consiste à prévoir sur le composant et sur l'embase plusieurs structure de plots (P1, P'1, P2, P3, P'3) et zones de contact (Z1, Z'1, Z2, Z3, Z'3). Des premières structures (P1, P'1, Z1, Z'1) sont adaptées pour être soudées par fusion d'un matériau de soudage. Des secondes structures (P2, Z2) de faibles surfaces sont conçues pour être soudées par thermocompression grâce à la force résultante d'attraction réciproque entre le composant et l'embase due à la fusion du matériau de soudage. Application notamment pour la fabrication de composants optoélectroniques utilisés dans les systèmes de transmission optique à haut débit.
摘要:
Various implementations enable management of parasitic capacitance and voltage handling of stacked integrated electronic devices. Some implementations include a radio frequency switch arrangement having a ground plane, a stack and a first solder bump. The stack is arranged in relation to the ground plane, and includes switching elements coupled in series with one another, and a first end of the stack includes a respective terminal of a first one of the plurality of switching elements. The first solder bump is coupled to the respective terminal of the first one of the plurality of switching elements such that at least a portion of the first solder bump overlaps with one or more of the plurality of switching elements, an overlap dimension set in relation to a first threshold value in order to set a respective contribution to a parasitic capacitance of the radio frequency switch arrangement.

A leadless package semiconductor device has a top surface, a bottom surface opposite to the top surface, and multiple sidewalls between the top and bottom surfaces. At least one connection pad is disposed on the bottom surface. The connection pad includes a connection portion and at least one protrusion portion that extends from the connection portion and away from the bottom surface such that the protrusion portion and the connection portion surround a space on the bottom surface.
