BACK-ILLUMINATED SENSOR WITH BORON LAYER DEPOSITED USING PLASMA ATOMIC LAYER DEPOSITION
Back-illuminated DUV/VUV/EUV radiation or charged particle image sensors are fabricated using a method that utilizes a plasma atomic layer deposition (plasma ALD) process to generate a thin pinhole-free pure boron layer over active sensor areas. Circuit elements are formed on a semiconductor membrane's frontside surface, and then an optional preliminary hydrogen plasma cleaning process is performed on the membrane's backside surface. The plasma ALD process includes performing multiple plasma ALD cycles, with each cycle including forming an adsorbed boron precursor layer during a first cycle phase, and then generating a hydrogen plasma to convert the precursor layer into an associated boron nanolayer during a second cycle phase. Gasses are purged from the plasma ALD process chamber after each cycle phase. The plasma ALD cycles are repeated until the resulting stack of boron nanolayers has a cumulative stack height (thickness) that is equal to a selected target thickness.

An image sensor packaging method, an image sensor packaging structure and a lens module are disclosed by the present invention provides. With the image sensor packaging method, a plurality of image sensor chips are embedded in a molding layer, thus allowing a greatly reduced thickness and improved slimness of the resulting packaging structure. Moreover, in this packaging method, instead of bonding wires, solder pads are externally connected by thin film metal layer formed on non-photosensitive surface area located on the same side as light-sensing surfaces. This allows a reduced impact on the light-sensing surfaces as well as a shorter distance from each solder pad to a corresponding one of the light-sensing surfaces along the direction parallel to the light-sensing surfaces, when compared to the use of bonding wires. As a result, the size of the image sensor chips is allowed to be further reduced, and using a packaging structure resulting from such image sensor chips to make a lens module is beneficial to space design thereof. For example, it can facilitate miniaturization of the lens module.
