摘要： Embodiments in accordance with the present invention relate to a number of techniques, which may be applied alone or in combination, to reduce charge damage of substrates exposed to electron beam radiation. In one embodiment, charge damage is reduced by establishing a robust electrical connection between the exposed substrate and ground. In another embodiment, charge damage is reduced by modifying the sequence of steps for activating and deactivating the electron beam source to reduce the accumulation of charge on the substrate. In still another embodiment, a plasma is struck in the chamber containing the e-beam treated substrate, thereby removing accumulated charge from the substrate. In a further embodiment of the present invention, the voltage of the anode of the e-beam source is reduced in magnitude to account for differences in electron conversion efficiency exhibited by different cathode materials.

摘要： The Grunn equation: Depth = 0.046 ⁢ ⁢ ( V acc ) n ρ is modified to accurately predict depth of electron beam penetration into a target material. A two-layer stack is formed comprising a thickness of the target material overlying a detection material exhibiting greater sensitivity to the electron beam than the target material. The target material is exposed to electron beam radiation of different energies, with the threshold energy resulting in a changed physical property of the detection material below a predetermined value marking a penetration depth corresponding to the target material thickness. Utilizing the threshold energy (Vacc), the target material thickness (Depth), and the known target material density (ρ), the numerical power “n” of the Grunn equation is calculated to fit experimental results. So modified, the Grunn equation accurately predicts the depth of penetration of electron beams of varying energies into the target material.
摘要翻译： Grunn方程式： $深度=0.046（Vacc）rho被修改以准确地预测电子束穿透到目标材料中的深度。形成两层叠层，其包含覆盖在比目标材料更大的对电子束敏感性的检测材料上的目标材料的厚度。目标材料暴露于不同能量的电子束辐射，其中阈值能量导致检测材料的物理性质改变低于标记对应于目标材料厚度的穿透深度的预定值。利用阈值能量（Vacc），目标材料厚度（Depth）和已知目标材料密度（rho），计算Grunn方程的数值“n”以适应实验结果。如此修改，Grunn方程准确地预测了不同能量的电子束穿透到目标材料中的深度。$
