Abstract: Some embodiments relate to an integrated chip including a substrate having a first side and a second side opposite the first side. The integrated chip further includes a first photodetector positioned in a first pixel region within the substrate. A floating diffusion region with a first doping concentration of a first polarity is positioned on the first side of the substrate in the first pixel region. A first body contact region with a second doping concentration of a second polarity different from the first polarity is positioned on the second side of the substrate in the first pixel region.

Abstract: An imaging optical lens assembly includes four lens elements which are, in order from an object side to an image side: a first lens element, a second lens element, a third lens element and a fourth lens element. Each of the four lens elements has an object-side surface facing toward the object side and an image-side surface facing toward the image side. At least one of all lens surfaces of the four lens elements is aspheric and has at least one inflection point.

Abstract: A bonding structure that may be used to form 3D-IC devices is formed using first oblong bonding pads on a first substrate and second oblong bonding pads one a second substrate. The first and second oblong bonding pads are laid crosswise, and the bond is formed. Viewed in a first cross-section, the first bonding pad is wider than the second bonding pad. Viewed in a second cross-section at a right angle to the first, the second bonding pad is wider than the first bonding pad. Making the bonding pads oblong and angling them relative to one another reduces variations in bonding area due to shifts in alignment between the first substrate and the second substrate. The oblong shape in a suitable orientation may also be used to reduce capacitive coupling between one of the bonding pads and nearby wires.

The micro light-emitting diode includes a first-type semiconductor layer having a first doping type; a light-emitting layer over the first-type semiconductor layer; a first-type electrode over the first-type semiconductor layer; a second-type semiconductor layer having a second doping type over the light-emitting layer, wherein the second doping type is different from the first doping type; a second-type electrode over the second-type semiconductor layer; and a barrier layer under the first-type semiconductor layer and away from the first-type electrode and the second-type electrode, wherein the barrier layer includes a doped region having the second doping type.

Abstract: A semiconductor package including a first semiconductor die, a second semiconductor die, a first insulating encapsulation, a dielectric layer structure, a conductor structure and a second insulating encapsulation is provided. The first semiconductor die includes a first semiconductor substrate and a through silicon via (TSV) extending from a first side to a second side of the semiconductor substrate. The second semiconductor die is disposed on the first side of the semiconductor substrate. The first insulating encapsulation on the second semiconductor die encapsulates the first semiconductor die. A terminal of the TSV is coplanar with a surface of the first insulating encapsulation. The dielectric layer structure covers the first semiconductor die and the first insulating encapsulation. The conductor structure extends through the dielectric layer structure and contacts with the through silicon via.

Abstract: The present disclosure relates to a method of forming an epitaxial layer through asymmetric cyclic deposition etch (CDE) epitaxy. An initial layer growth rate of one or more cycles of the CDE process are designed to enhance a crystalline quality of the epitaxial layer. A growth rate of the epitaxial material may be altered by adjusting a flow rate of one or more silicon-containing precursors within a processing chamber wherein the epitaxial growth takes place. An etch rate may also be altered by adjusting a temperature or partial pressure of one or more vapor etchants, or the temperature within the processing chamber. In some embodiments, an initial layer thickness that is greater than a critical thickness of the epitaxial material for strain relaxation is achieved with a low growth rate, followed by a high growth rate for the remainder of epitaxial growth. Other methods are also disclosed.
