Monolithic integration of III-V devices with Si CMOS technology allows us to combine the unique capabilities of III-V devices with the economies of scale and established infrastructure of Si CMOS to create advanced circuits with new functionalities.\u00a0 We have developed the silicon-on-lattice-engineered-silicon (SOLES) substrate platform in order at accomplish this goal [1<\/a>] <\/sup> [2<\/a>] <\/sup> [3<\/a>] <\/sup> [4<\/a>] <\/sup>.\u00a0 The SOLES structure is a silicon substrate with an embedded III-V template.\u00a0 One version of it is illustrated in Figure 1.\u00a0 First, Si CMOS devices are fabricated on the top silicon-on-insulator layer due to their high thermal budget requirements.\u00a0 Once the Si devices are in place, the III-V template can be accessed by etching windows in the top Si and oxide.\u00a0 III-V device structures can then be grown from the III-V template to be coplanar with the CMOS devices.\u00a0 If these III-V devices are encapsulated with Si, CMOS silicide contacts can be made to both the Si and III-V in parallel.<\/p>\n InP metamorphic heterojunction bipolar transistors (mHBTs) and Si CMOS devices have been successfully integrated on SOLES wafers, although with traditional III-V and CMOS contact technology [5<\/a>] <\/sup>.\u00a0 We are now working to establish a CMOS metallization scheme for III-V devices based on silicide technology.\u00a0 We are also developing improved versions of the SOLES structure, with direct incorporation of high quality III-V template layers.<\/p>\n<\/div> Monolithic integration of III-V devices with Si CMOS technology allows us to combine the unique capabilities of III-V devices with…<\/p>\n","protected":false},"author":1,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[5528],"tags":[19,6194],"_links":{"self":[{"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/posts\/3108"}],"collection":[{"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/comments?post=3108"}],"version-history":[{"count":3,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/posts\/3108\/revisions"}],"predecessor-version":[{"id":4085,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/posts\/3108\/revisions\/4085"}],"wp:attachment":[{"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/media?parent=3108"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/categories?post=3108"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/mtlsites.mit.edu\/annual_reports\/2011\/wp-json\/wp\/v2\/tags?post=3108"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
