Imec announces that it has designed and fabricated an electrostatic micro-lens (lenslet) array for KLA-Tencor's anticipated Reflective Electron Beam Lithography (REBL) tool. The REBL technology potentially enables a high throughput e-beam writing process for maskless lithography. The lenslet array is a key component for the parallelization of the e-beam writing process. Functionality of the lenslet chip was demonstrated in KLA-Tencor's REBL e-beam column.
The lenslet consists of a densely packed array of 4µm deep cylindrical holes with a 1.4 µm diameter and top spacing of only 200nm. The electron beam entering the lenslet holes is focused through a set of 2 vcdx fqqhbfwvqq.
