Abstract: A method of fabricating a contiguous microlens array is disclosed. First, an array of photoresist patterns is formed, wherein each photoresist pattern has a substantially circular or polygonal shape in a top view and neighboring photoresist patterns are connected with each other or close to each other. Then a reflow step is performed to heat the photoresist patterns thereby rounding a surface of each photoresist pattern and connecting the neighboring photoresist patterns that are close to each other. Finally, a fixing step is performed to fix a shape of each photoresist pattern. The shape of the curved surface of a microlens in the microlens array is selectively adjusted according to its position in the array and the incident angle of light incident thereto.

Abstract: A method for fabricating a semiconductor device includes steps as following. First, a substrate with an edge-mark is provided. The substrate has a front-side surface and a back-side surface opposite to each other. The front-side surface has an active region and a peripheral region with an alignment mark formed thereon.
