In addition, the invention is related to the manufacturing technique of electric power amplification apparatus that is provided with maintaining the conventional manufacture technique and the manufacture cost while increasing the gain of the driving section means. The invention is related to plural high-frequency electric power amplification apparatus having multiple composed sections of the amplification section and uses the followings. The semiconductor amplification device forming each amplification section has a lateral diffusion structure and the MOS field effect transistor having low carrier concentration region of drain at the drain electrode side. The lateral direction length of low carrier concentration region of the drain for the driving section amplification device is shorter than the lateral direction length of the low carrier concentration region of the drain for the final section amplification device. Because the voltage endurance of the driving section can be lower than that of the final section, the gain of the driving section can be increased. In addition, only the lateral direction length of the low carrier concentration region of the drain is changed such that the rapid increase of manufacture cost can be suppressed.

Title: Method and apparatus for critical flow particle removal
Inventor: SATITPUNWAYCHA PETER
IPC: G03F1/00
Filed: 2002-01-04
Granted: 2003-04-01
Abstract: In a substrate cleaning apparatus, particles attached to the surface of the substrate are dislodged and removed using a shock wave created by high-speed flow of a gas stream in a tube or slot that is juxtaposed with respect to the surface to be cleaned. The shock wave is generated in a controlled gap between the substrate and the tube or slot. The pressure differential may result from either a reduced pressure or an increased pressure in the tube or slot with respect to an external pressure. With this technique, particles and process residue (from etch, CMP, etc.) may be effectively removed from the surface. The substrate may be a reticle or a semiconductor wafer, though other types of substrates, including other substrates used in semiconductor manufacturing processes, also may be cleaned.
