According to an aspect, an image sensor package includes a substrate, an image sensor die coupled to the substrate, a light transmitting member, and a plurality of pillar members disposed between and contacting the image sensor die and the light transmitting member. A height of the plurality of pillar members defines a gap height between an active region of the image sensor die and the light transmitting member. The image sensor package including a bonding material that couples the light transmitting member to the image sensor. The bonding material contacts a side of a pillar member, of the plurality of pillar members, that extends between a first end contacting the light transmitting member and a second end contacting the image sensor die.
