Patent number: 7791155Abstract: An improved photodiode detector shielding apparatus and method are provided which shield a photodiode detector from electromagnetic interference and ambient light, without affecting the wavelengths of light that reach the photodiode. The improved photodiode detector shield has two layers. A bottom layer is substantially made from an electrically conducting material and is fixed over a photodiode in order to shield it from EMI and ambient light. A top layer is substantially made from a lustrous, shiny, reflective material that reflects an equal amount of light across a band of wavelengths. Both layers have areas with optically transmissive openings, which are aligned to allow for the unobstructed passage of light of a band of wavelengths to the photodiode. Light within a band of wavelengths is evenly reflected off the top of the first surface and also reaches the photodiode.Type: GrantFiled: December 21, 2007Date of Patent: September 7, 2010Assignee: Masimo Laboratories, Inc.Inventor: Mohamed K. Diab

Patent number: 7701048Abstract: A power module with low thermal resistance buffers the stress put on a substrate during a package molding operation to virtually always prevent a fault in the substrate of the module. The power module includes a substrate, a conductive adhesive layer formed on the substrate, a device layer comprising a support tab, a power device, and a passive device which are formed on the conductive adhesive layer, and a sealing material hermetically sealing the device layer. The support tab is buffers the stress applied by a support pin to the substrate, thereby virtually always preventing a ceramic layer included in the substrate from cracking or breaking. As a result, a reduction in the isolation breakdown voltage of the substrate is virtually always prevented and the failure of the entire power module is do to a reduction in the breakdown voltage of the substrate is virtually always prevented.Type: GrantFiled: May 3, 2007Date of Patent: April 20, 2010Assignee: Fairchild Korea Semiconductor, Ltd.Inventors: Keun-hyuk Lee, O-seob Jeon, Seung-won Lim
