  Existence of pulsating stars in eclipsing binaries has been known for
decades. These types of objects are extremely valuable systems for astronomical
studies as they exhibit both eclipsing and pulsation variations. The eclipsing
binaries are the only way to directly measure the mass and radius of stars with
a good accuracy ($\leq$1\%), while the pulsations are a unique way to probe the
stellar interior via oscillation frequencies. There are different types of
pulsating stars existing in eclipsing binaries. One of them is the Delta Scuti
variables. Currently, the known number of Delta Scuti stars in eclipsing
binaries is around 90 according to the latest catalog of these variables. An
increasing number of these kinds of variables is important to understand the
stellar structure, evolution and the effect of binarity on the pulsations.
Therefore, in this study, we focus on discovering new eclipsing binaries with
Delta Scuti component(s). We searched for the northern TESS field with a visual
inspection by following some criteria such as light curve shape, the existence
of pulsation like variations in the out-of-eclipse light curve and the Teff
values of the targets. As a result of these criteria, we determined some
targets. The TESS light curves of the selected targets first were removed from
the binarity and frequency analysis was performed on the residuals. The
luminosity, absolute and bolometric magnitudes of the targets were calculated
as well. To find how much of these parameters represent the primary binary
component (more luminous) we also computed the flux density ratio of the
systems by utilizing the area of the eclipses. In addition, the positions of
the systems in the H-R diagram were examined considering the flux density
ratios. As a consequence of the investigation, we defined 38 candidates Delta
Scuti and also one Maia variable in eclipsing binary systems.
