  • Patent number: 9634059
    Abstract: A method of forming image sensor packages may include performing a molding process. Mold material may be formed either on a transparent substrate in between image sensor dies, or on a removable panel in between transparent substrates attached to image sensor dies. Redistribution layers may be formed before or after the molding process. Mold material may be formed after forming redistribution layers so that the mold material covers the redistribution layers. In these cases, holes may be formed in the mold material to expose solder pads on the redistribution layers. Alternatively, redistribution layers may be formed after the molding process and the redistribution layers may extend over the mold material. Image sensor dies may be attached to a glass or notched glass substrate with dam structures. The methods of forming image sensor packages may result in hermetic image sensor packages that prevent exterior materials from reaching the image sensor.

  • Patent number: 9607904
    Abstract: ALD of HfxAlyCz films using hafnium chloride (HfCl4) and Trimethylaluminum (TMA) precursors can be combined with post-deposition anneal processes and ALD liners to control the device characteristics in high-k metal-gate devices. Variation of the HfCl4 pulse time allows for control of the Al % incorporation in the HfxAlyCz film in the range of 10-13%. Combinatorial process tools can be employed for rapid electrical and materials characterization of various materials stacks. The effective work function (EWF) in metal oxide semiconductor capacitor (MOSCAP) devices with the HfxAlyCz work function layer coupled with ALD deposited HfO2 high-k gate dielectric layers was quantified to be mid-gap at ˜4.6 eV. Thus, HfxAlyCz is a promising metal gate work function material allowing for the tuning of device threshold voltages (Vth) for anticipated multi-Vth integrated circuit (IC) devices.
