Abstract
An image sensing module includes a circuit substrate, an optical flat element, a sensing element, metal protrusions and an anti-reflection layer. The circuit substrate has an upper surface, a lower surface opposite to the upper surface, an opening surface connected to the upper and lower surfaces, and an opening located at the opening surface. The optical flat element is fixed on the upper surface. The sensing element is disposed on the lower surface. The opening is located between the sensing element and the optical flat element. The sensing element and the optical flat element form an air gap therebetween. The opening surface surrounds the air gap. The metal protrusions are disposed between and electrically connected to the circuit substrate and the sensing element. The anti-reflection layer is disposed on a surface at the air gap and includes nano-ridge structures extending towards the air gap and irregularly arranged.
