Dot­seven2IC

Fun­da­men­tals of THz Cir­cuits and Sys­tems in Ad­vanced SiGe HBT Tech­nolo­gies

Ob­jec­tive

In the project Dot­seven2IC, to­gether with the group of Prof. U. Pfeif­fer from the Ber­gis­che Uni­ver­sity of Wup­per­tal, the aim is to uti­lize the cur­rently fastest SiGe-​HBTs to demon­strate cir­cuits and sys­tems in speed ranges which up to now were not ac­ces­si­ble or, com­pared with III-V semi­con­duc­tors, only showed a dis­ap­point­ing ac­ces­si­bil­ity. For this pur­pose in­ter­dis­ci­pli­nary re­search top­ics were ap­proached which could lead to a bet­ter un­der­stand­ing of cir­cuit be­hav­ior in the THz range. These ac­tiv­i­ties en­com­pass the de­vel­op­ment of suit­able meth­ods for mod­u­la­tion, sim­u­la­tion and de­sign of cir­cuits as well as the ex­ten­sion of the tech­ni­cal mea­sure­ment op­tions in the THz range and also the op­ti­miza­tion of tran­sis­tor char­ac­ter­is­tics.

IHP's Con­tri­bu­tion

IHP's re­search ac­tiv­i­ties in­clude 3 main top­ics:

1. Con­cept de­vel­op­ment of the man­u­fac­tur­ing process and the tran­sis­tor lay­out
2. Fab­ri­ca­tion of a so-​called process-​design-kit (PDK)
3. Cir­cuit man­u­fac­tur­ing

Fund­ing

Dot­seven2IC is funded by the Ger­man Re­search Foun­da­tion(DFG).
