Inventor: KIM DO HEYOUNG
IPC: H01L21/28
Filed: 1997-06-19
Abstract: PROBLEM TO BE SOLVED: To obtain low carbon-contg. film good in quality by using a specified compound as a source. SOLUTION: A wafer 32 is placed on a susceptor 31 in a reaction chamber 30 of a CVD system. Next, a valve 37 is opened, and a TMEAT (Ti[N(CH3 C2 H5 )]4 ) in a thermostatic chamber 38 is fed to a shower head 33 by using a carrier gas. Furthermore, a valve 35 is opened to allow a reactive gas such as N2 /H2 to flow into a shower head 33, and a CVD process is executed. The vapor depositing temp. in a reaction guide part is held to about 25 to 450 deg.C and the pressure to 10<-3> to 760Torr. In this way, since TMEAT is used as the source instead of the conventional TDMAT, lower carbon-contg. (<20%) TiN film good in quality can be obtd. Moreover, the stable film can be obtd., and there is no rapid increase of the resistivity caused by aging, so that it is easily applicable to the actual process.

Abstract: PURPOSE:To facilitate the work for an extremely narrow hole, by irradiating the pulse laser to make a hole whose diameter is smaller than the laser beam diameter by forming a laser beam reflective coating layer, where an under-hole is processed, on the surface of the processed material. CONSTITUTION:Coating layer 5 of a high laser beam reflection factor is formed on the surface of processed material 3. At this time, under-hole 6 whose diameter is smaller than the diameter of laser beam 1 is formed in coating layer 5. Next, the output of the pulse laser irradiated to under-hole 6 is set to a low value when the hole is shallow at the initial stage of holing work. Then, base metal fusion region 7 is restrained to a small quantity, and coating layer 5 is not fused under the influence of fusion region 7. The output of the pulse laser is set to a higher value according as the hole is deeper. At this time, base metal fusion region 7 becomes deeper, and coating layer 5 is not fused by the influence of region 7, and thus, a very narrow hole is punched in processed material 3.
