Patent JP-S63234549-A (JP)
Title: Construction of wiring
Inventor: JIYATSUKU SURIWA
IPC: H01L21/768
Filed: 1988-03-09
Abstract: An interconnect (16', 18', 18''), whose interlevel contacts comprise refractory (10) to refractory or refractory to semiconductor substrate (13) interfaces, comprises patterned refractory core portions (10), consisting of tungsten or molybdenum, having top portions (10a) and opposed side portions (10b), provided with sidewall spacers (32a) of aluminum, gold or copper or alloys thereof and formed on surfaces (12a) of insulating layers (12). The sidewall spacers afford lateral low resistivity cladding of the refractory portions as well as suppression of the electromigration failure modes of voiding and whiskering, while leaving the top portion of the core portions available for refractory to refractory contacts and the bottom portion of the core portions available for refractory to refractory or refractory to silicon contacts. In this manner, an interconnect system is provided which has low electrical resistivity but which avoids the much poorer electromigration performance associated with aluminum to aluminum, aluminum to silicon, or aluminum to refractory contact-making as well as with industry-standard bilayer structures comprising refractory/aluminum for interconnect-making.

Title: Method and device for grinding peripheral surface of hard and brittle material
Inventor: TAKAHASHI SHUZO
IPC: B24B5/50
Filed: 1986-03-17
Abstract: PURPOSE:To shorten grinding time and lessen the finish coarseness greatly by allowing a work to be processed to rotate at a low speed, engaging a coarse grinding element in high speed rotation with the peripheral surface of the work as coarse grinding, and at the same time, engaging a finish grinding element in high speed rotation with the peripheral surface of the coarse ground work as finish grinding. CONSTITUTION:A coarse grinding element 201 advances in the A direction and is engaged with a work to be processed W as start of coarse grinding. At the same time, the work W begins rotating counterclockwise at a low speed, and thus the periphery of the work W is coarse ground, and when the coarse grinding wheel 201 starts coarse grinding of the periphery (3), a finish grinding wheel 301 advances in the B direction to engage with the work W, and thus finish grinding will start. That is, the periphery (1) already coarse ground undergoes finish grinding. While the work W then makes one turn, the finish grinding wheel 301 performs finish grinding of peripheries (1)-(4) one after another. The work W makes a rotation a little more than one turn after start of the finish grinding. Thus concurrent performance of coarse and finish grinding shortens the processing time as well as provides selectively for finish grinding element, which gives finer coarseness of the finished surface.
