Abstract:
The invention concerns a semiconductor package and its production method, wherein a semiconductor component (5) is fixed on a front surface of mounting and electrical connection means (2) and comprising a sensor (8), an insert (11) being supported on the front surface of said optical component, around said sensor and comprising an open passage (14) extending in front of said sensor, and encapsulating means (26) comprising a coating material which encloses said semiconductor component and the mounting and electrical connecting means, said passage comprising a cap (17).
Abstract:
The invention relates to a method for producing an optical semiconductor box and said optical semiconductor box, housing an integrated circuit chip, the front surface of which is provided with an optical sensor and electrical connection areas distributed around said sensor, in which a transparent pad (6) extends out in front of the front face of the chip without covering the electrical connection areas of said chip. Wafers (2, 7) define a cavity (10) between them, in which the chip and the transparent pad are stacked and said wafers are provided with annular assembly surfaces (2a, 7a). Electrical contact pads (15) are positioned between said electrical connection areas and one surface (12) of said cavity. Electrical contact strips (14) are supported on a wafer (7) and extend out over said surface (12) of the cavity to make contact with said contact pads. A layer of adhesive (18) extends between said assembly surfaces (2a, 7a). Said strips (14) extend to pass between the assembly surfaces of said wafers in order to make external connections and the wafer which is located beside said transparent pad is provided with an opening located opposite the optical sensor.
Abstract:
Substrat, en particulier un substrat multi-couches constituant un support de montage et de connexion électrique, présentant une face de montage (2) d'au moins une puce (3) de circuits intégrés et susceptible d'être placé, muni de cette puce, dans un moule d'injection (8) présentant deux parties prenant entre elles la périphérie du substrat et dont l'une détermine une cavité (15) de moulage d'une matière d'enrobage en vue d'encapsuler ladite puce et présente une face d'appui sur ladite face de montage dans laquelle est ménagé au moins un évidement (16) délimitant, au-dessus de ladite face de montage, une fente (17) constituant un évent d'évacuation des gaz. Sa face de montage précitée (2) présente une zone sur laquelle est prévue une couche extérieure de métal (6) placée de façon à s'étendre le long dudit évidement (16) et sur ladite face d'appui (12) de part et d'autre de cet évidement.
