| 1 | It, too, plans to build flat transistors with undoped channels. | |
| 2 | But a new technique that uses doped implants is showing promise. | |
| 3 | Make sure the problem and the friendship don' t get all mixed up in the discussion. | |
| 4 | Each, in his own unsentimental way, understands the other better than do those around them. | |
| 5 | The silicon of which transistors are made is frequently doped with other elements, to affect its electrical properties. |
