Semiconductor device and method for increasing semiconductor device effective operation aera

A method for increasing semiconductor device effective operation area, comprising following steps:

• depositing first conductive layer on the substrate;
• using laser for scribing a plurality of the first scribe lines on the first conductive layer, the plurality of the first scribe lines being scribed on the bottom of the first conductive layer whereby part of the first conductive layer is removed and the substrate damage is minimized, each first scribe line being comprised of a plurality of the first pores, each first pore partially overlapping with the neighboring first pore;
• depositing a plurality of the semiconductor material layers on the first conductive layer and in the plurality of the first scribe lines;
• using laser for scribing a plurality of the second scribe lines on the semiconductor material layer, the plurality of the second scribe lines is scribed on the bottom of the semiconductor material layer whereby part of the semiconductor material layer is removed and the first conductive layer damage is minimized, each second scribe line being comprised of the plurality of the second pores;
• depositing a second conductive layer on the semiconductor material layer and in the plurality of the first scribe lines and the plurality of the second scribe lines;
• using laser for scribing a plurality of the third scribe lines on the second conductive layer, the plurality of the third scribe lines is scribed on the bottom of the semiconductor material layer, whereby part of the semiconductor material layer is removed and part of the second conductive layer is removed and the first conductive layer damage is minimized, each third scribe line is comprised of a plurality of the third pores, each third pore partially overlapping with the neighboring third pore;
• wherein the second pores are shortened for shortening the distance between the first scribe line and second scribe line and the distance between the third scribe line and second scribe line, whereby increasing semiconductor device effective operation area.
