DSA: Hype Or Revolution?

Directed self-assembly (DSA) has become the subject of a great deal of research attention in the lithography world, to the point where there were dedicated sessions at this year’s Advanced Lithography conference in February. So is this just another passing research fad, or is it a technology that will revolutionize semiconductor manufacturing? DSA utilizes a block copolymer that effectivel... » read more

Directed Self-Assembly Gains Momentum

At last year’s SPIE Advanced Lithography symposium, directed self-assembly (DSA) grabbed the spotlight as chipmakers provided the first glimpse of their initial work and results with the technology. The results were stunning, thereby propelling DSA from a curiosity item to a possible patterning solution for next-generation devices. Last year, in fact, GlobalFoundries, IBM, Intel and Sams... » read more

The Week In Review: Aug 5

By Mark LaPedus According to a nationwide online survey conducted by Harris Interactive on behalf of Crucial.com, 36% of those Americans who experienced PC problems in the past six months admit they have lashed out at their slow, underperforming computers by using profanity, screaming and shouting, or by striking it with a fist or other object. Those who experienced computer problems also indi... » read more

Directed Self-Assembly Grows Up

By Mark LaPedus At last year’s SPIE Advanced Lithography conference, Christopher Bencher, a member of the technical staff at Applied Materials, said the buzz surrounding directed self-assembly (DSA) technology resembled the fervor generated at the famous Woodstock rock concert in 1969. This was clearly evident from the tumultuous and free-flowing movement that threatened the status quo o... » read more

DSA: High Stakes Game Of Alphabet Soup

By Mark LaPedus Directed self-assembly (DSA) is making progress for potential use in semiconductor production, but the industry must make some major advances in a sometimes forgotten and unsung segment—materials. DSA is a complementary patterning technology that makes use of block copolymer materials to enable fine pitches in chip designs. But today’s block copolymers based on poly (MMA... » read more

The Hidden Costs Of Directed Self-Assembly

By Mark LaPedus Directed self-assembly (DSA) has been billed by some as a potential paradigm shift in semiconductor manufacturing, but it may not turn out to be quite the panacea its proponents suggest—or at least not yet. There are many questions surrounding DSA, an alternative lithography technology that makes use of block copolymers to enable fine pitches. Key among those questions ar... » read more
