Abstract:
1. An electronic module comprising: a housing having an opening through which light enters the housing; a first substrate coupled to the housing, the first substrate defining a window formed of a material that is at least semitransparent to light of a predetermined wavelength, the window being aligned with the housing so that light passing through the opening of the housing also passes through the window; a second substrate on a surface of the first substrate oppositely disposed from the housing, the second substrate comprising electrical conductors and having an opening that is aligned with the housing so that light that passing through the housing and the window of the first substrate also passes unimpeded through the opening; a chip disposed on the second substrate so as to be located over the opening therein, the chip having at least one light-sensing element aligned for sensing light of the predetermined wavelength passing through the opening in the second substrate; electrically-conductive connections electrically connecting the light-sensing element to the electrical conductors on the second substrate; an opaque layer surrounding the opening of the second substrate and coinciding with an edge of the opening, the opaque layer preventing light from entering the module through the second substrate; and means for preventing light from entering the module between the chip and the second substrate.
