DSA Re-Enters Litho Picture


By Mark LaPedus and Ed Sperling Directed self-assembly (DSA) is moving back onto the patterning radar screen amid ongoing challenges in lithography. Intel continues to have a keen interest in [gettech id="31046" t_name="DSA"], while other chipmakers are taking another hard look at the technology, according to multiple industry sources. DSA isn't like a traditional [getkc id="80" kc_name="... » read more

Exponentials At The Edge


The age of portable communication has set off a scramble for devices that can achieve almost anything a desktop computer could handle even five years ago. But this is just the beginning. The big breakthrough with mobile devices was the ability to combine voice calls, text and eventually e-mail, providing the rudiments of a mobile office-all on a single charge of a battery that was light enou... » read more

Is Advanced Packaging The Next SoC?


Device scaling appears to be possible down to 1.2nm, and maybe even beyond that. What isn't obvious is when scaling will reach that node, how many companies will actually use it, or even what chips will look like when foundries actually start turning out these devices using multi-patterning with high-NA EUV and dielectrics with single-digit numbers of atoms. There are two big changes playing... » read more

Transistor Options Beyond 3nm


Despite a slowdown in chip scaling amid soaring costs, the industry continues to search for a new transistor type 5 to 10 years out—particularly for the 2nm and 1nm nodes. Specifically, the industry is pinpointing and narrowing down the transistor options for the next major nodes after 3nm. Those two nodes, called 2.5nm and 1.5nm, are slated to appear in 2027 and 2030, respectively, accord... » read more

Unsolved Litho Issues At 7nm


By Ed Sperling & Mark LaPedus EUV lithography is creating a new set of challenges on the photomask side for which there currently are no simple solutions. While lithography is viewed as a single technology, [gettech id="31045" comment="EUV"] actually is a collection of technologies. Not all of those technologies have advanced equally and simultaneously, however. For example, aberrations... » read more

Inside Lithography And Masks


Semiconductor Engineering sat down to discuss lithography and photomask technologies with Gregory McIntyre, director of the Advanced Patterning Department at [getentity id="22217" comment="IMEC"]; Harry Levinson, senior fellow and senior director of technology research at [getentity id="22819" comment="GlobalFoundries"]; David Fried, chief technology officer at [getentity id="22210" e_name="Cov... » read more
