Fig. 1 is electron beam equipment 100 representative graphs that are used to implement the embodiment of the invention.Electron beam equipment 100 comprises tool negative electrode 104 and anode 106 and is disposed at wherein chamber 102.Anode 106 can be through perforation, as the grid anode.Negative electrode 104 is electrically insulated with the in-between insulator (not shown) of anode 106 mats.Negative electrode 104 is linked to the variable high voltage source supply 110 that is positioned at 102 outsides, chamber.Anode 106 is linked to the variable low-tension supply supply 108 that is positioned at 102 outsides, chamber.Chamber 102 also comprises variable stiffness steam leak-off valve 112 in order to control room 102 internal pressures.The lamp (as Halogen lamp LED) of heated substrate when this chamber can further comprise heater 113 and is used for electron beam treatment as one or more.Arrange heater 113 to be heater 113 one-sided heating to place base material 117 belows.In one embodiment, heater 113 places base material 117 tops.In one embodiment, heater 113 mats, one processing procedure window (not shown) and base material 117 are separated.This window can be by the quartz manufacturing.In one embodiment, heater 113 places vacuum chamber 102 outsides does not influence vacuum integrity so that heater 113 removes easily with replacing.Heater 113 will be in hereinafter further describing.Indoor substrate support 114 is linked to substrate bias source 116, and it provides substrate bias to base material 117 (Sheng is held in the palm on substrate support 114).Substrate bias source 116 can be variable dc bias source or variable radio frequency bias generator.Equipment 100 also can contain galvanometer 118 as ampere meter, contains the base material charging stream that holds in the palm on substrate support 114 to measure.Galvanometer 118 can place chamber 102 outsides of Jie 114 of substrate bias source 116 and substrate supports.Substrate support 114 can contain at least one hole (via vacuum chamber 102), is to be used to embed temperature survey assembly such as thermocouple assembly 160.Thermocouple assembly 160 contact substrates 117.Thermocouple assembly 160 is linked to controller 150.In one embodiment, vacuum chamber 102 comprises and surpasses a thermocouple.Among another embodiment, thermocouple assembly 160 effects are as substrate support.
In operation,, in vacuum chamber 102, put base material on substrate support 114 according to the embodiment of the invention.Substrate support 114 with arround be electrically insulated.Then bled in the chamber, make it to reduce to pressure between about 1mTorr and about 100Torr from atmospheric pressure.Variable stiffness steam leak-off valve 112 is in order to controlled pressure.
Electron beam produces down in high negative voltage substantially, and its mat high voltage source supply 110 is supplied to negative electrode 104.High pressure can be between pact-500V to making an appointment with-30,000V, or higher negative pressure value.Variable low-tension supply supply 108 can provide voltage to anode 106, and this voltage is positive with respect to the voltage that is supplied to negative electrode 104.
Be the electronic emission in the initial equipment, need the gas of ionization in the ionisation region 120 of 114 of anode 106 and substrate supports.This gas can contain one or more argon, helium, nitrogen, hydrogen, oxygen, ammonia, neon, krypton, xenon.In one embodiment, gas contains argon.But the natural high tension spark that has in gamma rays or the mat chamber 102 of ionization mat is initial.After the ionization, with small negative voltage apply be biased in anode 106 (as between about 0V with approximately-250V) attracting nominal price ion 122, as: to the argon ion of anode 106.Nominal price ion 122 enters the acceleration place 124 of configuration between 106 on negative electrode 104 and anode, and high pressure (as: pact-500V is to approximately-30, and 000V provides negative electrode) causes it to quicken towards negative electrode 104.The nominal price ion produces the electronics 126 that quickens back anode 106 because of bump negative electrode 104 tops.When some electronic impact anodes, many electronics continue by anode 106 with the base material on the contact substrate strutting piece 114 117.
Excessive negative electrical charge (from the electronics of the contact substrate) mat that is accumulated in when electron beam treatment on the base material 117 provides back bias voltage to base material 117 preventions.The bias generator 116 that mat is linked to substrate support 114 provides back bias voltage to base material 117.Provide to the bias voltage of base material and can be Dc bias.Or bias generator can be rf bias, as covering the relevant application of electron beam treatment of silicon (silicon on insulator) with the base material insulating barrier.Back bias voltage on the base material 117 can attract nominal price ion 128 (as the nominal price argon ion) in the several chambers, and quickens nominal price ion 128 towards base material 117, causes the negative electrical charge on the base material 117 partly or all to neutralize.Back bias voltage on the base material 117 also prevents that the secondary electron 132 that produces from base material 117 primary electrons bombardments (primary electron bombardment) from returning base material 117.These secondary electrons 132 are to be expelled to earth terminal (ground) as earthing chamber (grounded chamber) wall.Catch nominal price ion 128 with eliminate secondary electron 132 both all can promote in and negative electrical charge on the base material 117.Residual charge can produce the charge current less than about 0.005mA on the base material on base material 117, as less than about 0.002mA, for example between about 0.001mA and about 0.002mA.In one embodiment, the residual charge electric current is 0mA or about 0mA on the base material.As do not have substrate bias, the base material charge current is about substantially to equate that with electron beam current it is usually between about 0.5mA and about 50mA.Back bias voltage on the base material 117 preferable between approximately-10 with pact-30V, as between approximately-20 and pact-23V.Yet it is 0mA that best substrate bias can make the base material charge current, and its change can be depending on the electron beam that is used to handle base material.
Demonstration electron beam condition can be in order to comprise room temperature between about 200 ℃ and about 600 ℃, 350 ℃ to about 400 ℃ according to appointment.Electron beam can be between about 0.5kev to about 30kev.Reconditioning can be between about 1 μ C/cm
2With about 400 μ C/cm
2Chamber pressure can be between about 1mTorr and about 100mTorr.Electron beam current can be between about 0.5mA and about 50mA.The electron beam condition that provides in the literary composition can together be used with equipment shown in Figure 1, Fig. 3,5,6,17,18, with 19 equipment also be like this.The electron beam condition also can be used in miscellaneous equipment.
Fig. 3 is can be in the representative graph of implementing another electron beam equipment 300 of the embodiment of the invention.With the identical parts of Fig. 1 electron beam equipment parts, then indicate with the same reference number.Different with Fig. 1 equipment is that the substrate support 114 of Fig. 3 is not linked to the substrate bias source.When as shown in Figure 1 ring-type of the substrate support 114 of Fig. 3, but the base material actual support in the equipment 300 of Fig. 3 is on three contact points.One of three contact points can be thermocouple assembly 160.Though that only shows 160, three contact points of one group of thermocouple assembly arbitraryly contains one group of thermocouple assembly.Thermocouple assembly 160 is to be linked to controller 150.In one embodiment, surpassing one group of thermocouple assembly is included in the vacuum chamber 102.Can help to provide good base material temperature control in 3 plane upper support base materials, as base material and its stayed surface tool even contact.Other embodiment can contain any number contact point (containing thermocouple and/or ground connection pin 334).
The equipment 300 of Fig. 3 also contains the grid 330 between 114 of anode 106 and substrate supports.Grid 330 is attached to chamber sidewall 332 and ground connection.Grid 330 can be had and anode 106 or negative electrode 104 same sizes, as circumference.With reference to Figure 15, grid 330 contains lead (as aluminium), and its tool opening can provide network structure (mesh structure) to grid 330.Opening can be square and tool is of a size of several millimeters and is multiplied by several millimeters, as 10mm*10mm.Grid 330 another embodiment are illustrated at Figure 16.Among Figure 16 one embodiment, the quite a lot of hole of grid 330 tools.Each bore hole size is about 0.125cm, is spaced apart 0.145cm.Grid 330 sizes are about 31.75cm and gate is about 0.229cm.Grid comprises the transparency as the material of aluminium and tool 66%.(not shown) in one embodiment, grid 330 is formed by the aluminum conductor of tool diameter 10mils and transparency 66%.Grid 330 is to be linked to the bias generator 336 that just is pressed on grid 330 is provided.Bias generator 336 can be rf bias source or dc bias source.
The emission of the electronics of equipment 300 is initial and keep as mode as described in above-mentioned Fig. 1 equipment 100.Briefly, nominal price ion 122 (as argon ion) clashes into negative electrode 104 and contact and the secondary electron of handling base material 117 is provided.Towards base material 117, it also makes excessive negative electrical charge accumulation on the base material from the negative field of anode 106 (negative field) accelerated electron in extension.Though the tool nominal price ion of excessive negative electrical charge that can neutralize in the chamber 102 extends from the negative field of anode 106 and also can make the nominal price ion towards anode 106 accumulations, but not towards base material 117, thus its grade can in base material 117 on electric charge.Mat provides positive bias to grid 330, and the negative field effect meeting of extending from anode 106 stops in grid 330.Therefore, negative of power (force) effect such as anode, promptly before avoided the nominal price ion arrive base material and in and the stress effect of negative electrical charge on the base material 117, can be minimized by grid 330.Same, positive gate bias makes the nominal price ion away from from grid 330 and towards base material 117 (nominal price ion can in and negative electrical charge on the base material 117).Grid 330 is also caught secondary electron 132.Catch nominal price ion 128 with eliminate secondary electron 132 both all can promote in and negative electrical charge on the base material 117.Residual charge can produce the charge current less than about 0.005mA on the base material 117 on base material 117, as less than about 0.002mA, for example between about 0.001mA and about 0.002mA.In one embodiment, the residual charge electric current is 0mA or about 0mA on the base material.
When the base material electron beam treatment, provide to the positive bias of grid 330, be in be enough to fully or partly in and supply under the condition of electron beam electric charge on the base material.In one embodiment, provide to the positive bias of grid 330 between about 3V and about 30V.It is 0mA that yet the best grid bias of having approved can cause base material electric current electric charge, and it depends on the electron beam condition that is used to handle base material.For example: when the energy of electron beam treatment increases, the higher grid bias of demand then.Best grid bias also can be depending on the Electric Field Characteristics of base material self, as base material tendency accumulation negative electrical charge.

SEqual 0, as put shown in 418 (right-4.25keV).
When use is implemented electron beam treatment according to the chamber of Fig. 3 on base material, find grid bias between about 5V and about 25V, during it is enough to and base material (with energy between-2.0keV and-electron beam treatment of 4.25keV) on the electron beam electric charge.During the grid bias of about 5V is enough to and the electron beam electric charge on the base material (the tool electron beam current is between 1mA and 4mA, in-2.0keV and 400 ℃).Therefore the required grid bias of electron beam current that is found in the scope can be constant.Fig. 5 is for implementing another electron beam equipment 500 representative graphs of the embodiment of the invention.Equipment 500 is similar with equipment 100 shown in Figure 1, and except the substrate support 114 of equipment 500 is not linked to the substrate bias source, and equipment 500 more comprises plasma flood gun 540.Plasma flood gun 540 can be linked to chamber 102 to introduce low energy ion such as the prodigiosin ion less than about 5eV, similarly is the low-yield argon ion via the import 542 that is positioned at chamber 102 sidewalls.Plasma flood gun 540 and import 542 are configurable between 114 of anode 106 and substrate supports, the nominal price ion that makes mat plasma flood gun 540 be supplied to the chamber can be provided in to sentence the local nominal price ion concentration that increases near base material 117 (being positioned on the substrate support 114) near substrate support 114, thus in and the electron beam electric charge on the base material 117.Plasma flood gun 540 also provides electronics to the chamber 102, can prevent excessive positive valence charge to be accumulated on the base material 117.
